Definitions

  • the present invention relates to a drum of a machine for the careful treatment of clothes, particularly of a washing machine, a washer-dryer, a tumble dryer or suchlike according to the pre-characterizing part of claim 1.
  • the invention also relates to a machine for the careful treatment of clothes with a drum of this type.
  • EP 1,568,812 A2 and EP 1,505,188 A2 describe such a drum (200 in Fig. 12 ) of a washing machine according to the pre-characterizing part of claim 1, with a drum casing (400) which is in principle cylindrical in its basic form, with a cylinder axis forming the axis of rotation (A), about which the drum casing (400) can rotate.
  • the drum casing (400) has a tubular main casing part (400a), with a first and second front wall (400b, 400c), which are connected to a first and second axial edge region of the main casing part (400a).
  • the drum (200) also has at least one reinforcing piece that surrounds the main casing part (400a) on the outside circumference of the drum and counteracts the bulging of the main casing part (400a) under the influence of the centrifugal force (indicated in Fig. 12 by a thick dashed line) during the rotation of the drum (200).
  • This ensures a reliable connection between the first and second front wall (400b, 400c) on the one hand, and the first and second axial edge region of the main casing part (400a) on the other hand, which could otherwise be damaged during a rapid rotation of the drum (200), with pronounced bulging of the main casing part (400a).
  • the reinforcing piece is respectively a reinforcing strip (500) or a reinforcing metal band, that is to say, a metal band in the form of a thin metal plate.
  • GB-A-841783 discloses a drum according to the preamble of claim 1.
  • the reinforcing strip (500) basically offers a high-quality solution
  • the production of the reinforcing strip (500) and the fitting of strip (500) in the drum are quite complicated and expensive as far as the production and fitting methods are concerned, and call for special tools and machinery.
  • the cross-section of the reinforcing strip (500) should almost always be slightly raised like an arc to ensure that the convex side of the strip can then be positioned in such a way that the edges of the strip (500) do not rub against the drum later.
  • the fitting of the pretensed reinforcing strip (500) to the drum requires a strong mechanical force, as well as special preventive measures or tensing components in said reinforcing strip (500).
  • Such reinforcing strips (500) therefore cannot be adapted to drums of different shapes and sizes, or can only be adapted to them by the use of extremely strong forces, for example in different washing machines or machines for the careful treatment of clothes.
  • the task or technical problem of the present invention is to provide a drum with a reinforcing piece of the type mentioned at the beginning, which can be produced simply and effectively, can be fitted to the main casing part, and even so reliably counteracts the bulging of the main casing part during the rapid rotation of the drum, and can also be used in drums of different shapes and sizes.
  • a machine for the careful treatment of clothes with a drum of this type should also be available.
  • This task is accomplished according to a first aspect of the invention by a drum according to the invention, with characteristics set out in claim 1.
  • This drum of a machine for the careful treatment of clothes is provided with a drum casing that is essentially cylindrical in its basic form, with a central cylinder axis that forms an axis of rotation about which the drum can rotate, where the drum casing has a tubular main casing part with a first and a second front wall, which are connected to a first and second axial edge region of the main casing part, and it also has at least one reinforcing piece that surrounds the main casing part over the outside circumference of the drum and counteracts the bulging of the main casing part during the rotation of the drum under the influence of the centrifugal force, characterized in that the reinforcing piece is at least one cord-like component, which encircles the outside circumference of the main casing part at least once.
  • the drum is characterized in that the reinforcing piece is at least one cord-like component that is passed around the circumference of the main casing part at least once.
  • the term "cord-like component” is used to denote any type of component made at least with one wire and at least one fiber or at least one filament or similar elongated and ductile (and therefore also flexible) component for the transmission of forces of traction.
  • the cord-like component is made of a number of separate wires, cords, fibers or filaments, which are for example twisted, braided or grouped together to form one or more strands by some optional other means.
  • the cord-like component also has a certain elasticity.
  • the cross-section of the cord-like component or the profile of its cross-section is preferably essentially circular, elliptical or at least round.
  • the reinforcing piece is a cord-like component
  • the cord-like component can be simply unwound during the manufacture of a reel, cut to the required length, passed around the drum and fixed to it. No special tools or machines are needed for this operation.
  • the cord-like component can also be a standard one, such as for example normal stainless steel wires and suchlike. These have by nature a circular or round cross-section that ensures that the cord-like component, in the final state of fitting and working in the drum, does not rub against the outside surface. Unlike in the case of the prior art described above, there is no need in this case for any treatment or deformation of the reinforcing piece.
  • the cord-like component can also be encircled in the pretensed state, around the outside circumference of the main casing part and fixed in this state in a relatively simple way without costly procedures. Due to the ductility of the cord-like component, it can also be easily mounted around the main casing part in several turns or passes and at one or more angles of tilt, and in this way it can reach, if necessary, different points on the outside circumference of the main casing part. This makes it possible to reinforce the drums in a simple and effective form and manner at the points that are subjected to particularly strong forces.
  • the cord-like component can also be used for reinforcing drums of different sizes and/or drums of different types of machines for the careful treatment of clothes, without calling for an essential adaptation or modification of the cord-like component or for tools for fitting it.
  • the production of the drum according to the invention is therefore simpler, more effective and more economic than that of known drums.
  • the component acts by securely and reliably counteracting the undesirable bulging of the main casing part during the rapid rotation of the drum (for example at a speed of 1400 rpm or more).
  • the machine for the careful treatment of clothes in particular a washing machine, a washer-dryer, a tumble dryer or suchlike, has a drum according to one or more of claims 1-26.
  • the machine for the careful treatment of clothes basically makes it possible to achieve the same technical advantages as those set out above in connection with the drum according to the invention.
  • Fig. 1 shows a diagrammatic longitudinal cross-section, not drawn to scale, taken across a drum (2) according to the invention in a first embodiment, the drum being the drum of a washing machine here.
  • This drum (2) has a drum casing (4), which is essentially cylindrical in its basic form and has a central cylinder axis that forms an axis of rotation (A), about which the drum (2) can rotate.
  • the drum casing (4) has a tubular main casing part (4a), with a first and a second front wall (4b, 4c), which are connected to a first and second axial edge region (RB 1 , RB 2 ), these being shown in the drawing by a dot-and-dash circle.
  • the connection is achieved in this example by a folded joint (6). Welded joints, the integral coupling of said parts, or any other suitable optional forms of coupling are also possible.
  • the drum (2) also has at least one reinforcing piece, which encircles the main casing part (4a) on the outside circumference of the drum (2) and which counteracts the bulging of the main casing part (4a) that occurs during the rotation of the drum (2) under the influence of the centrifugal force (this bulging is indicated in Fig. 1 by a thick dashed line).
  • the reinforcing piece is at least one cord-like component (8) (called simply "cord (8)” in the following), which encircles the outside circumference of the main casing part (4a) at least once. In the embodiment under discussion, a single turn is envisaged. In the final, mounted state of the cord (8), the latter preferably encircles the main casing part (4a) in the pretensed form.
  • the cord (8) is arranged centrally with respect to the axial extension of the main casing part (4a).
  • the cord (8) used in this embodiment is a standard steel cable that is made of stainless steel and is corrosion-proof.
  • the cord (8) has a diameter of about 2.5 mm and basically a round cross-section. Other diameters are of course also possible in any application, depending on the size of the drum (2) and on the planned speed of rotation.
  • the cord (8) is preferably made of a number of separate elements that are twisted, stranded together or combined in another way. However, in a very simple embodiment, it can also be a single length of wire or suchlike.
  • the cord (8) can thus also be made of a number of non-metallic fibers, a number of filaments or a composite fibrous material.
  • FIGs. 2 and 3 show further details of the drum (2) according to the invention.
  • Fig. 2 shows in this case a diagrammatic external perspective view of a first site of the drum (2) according to the invention illustrated in Fig. 1 , with a view taken in the direction along its longitudinal axis or axial direction (compare the reference symbol A).
  • Fig. 3 shows a diagrammatic external perspective view of a second site of the drum (2) according to the invention illustrated in Fig. 1 , again with a view taken in the direction along its longitudinal axis or axial direction.
  • the tubular main casing part (4a) is made from a basic sheet material (here a stainless steel plate), which is deformed to obtain a tubular structure with two edges of the sheet. These correspond to each other and are inserted over an extended inserting region (B F ) that extends lengthways, basically parallel to the cylinder axis (A).
  • the inserting region (B F ) extends over the whole width of the main casing part (4a).
  • the two edges of the sheet are connected together with the aid of a folded joint (V F ).
  • the latter is provided with several grooved elbows (10) beyond the inserting region (B F ), where the longitudinal axes (10 A ) of the grooved elbows extend essentially in the direction of the circumference of the main casing part (4a).
  • the main casing part (4a) has on its outside circumferential surface several slot-like elbows (12), which extend essentially parallel to the axis of rotation (A) and form a type of blade-like breaker inside the main casing part (4a).
  • the transition zone of the slot-like elbows (12) toward the outside circumferential surface of the main casing part (4a) is rounded.
  • the cord (8) is in the form of a finite length of cord whose ends (8a, 8b) are joined together by a cord-joining component (14) in the mounted state, that is to say, in a state in which it is fixed to the main casing part (4a).
  • the cord (8) can also be an infinite cord, for example in the form of a ring.
  • the cord-joining component (14) is preferably a cord-joining component that is chosen from a group of cord-joining components comprising: a shape-based joint, a joint working by friction, an adhesive or glued joint, in particular a knotted joint, a plaited joint, an interlacing joint, a spliced joint, a (strong) welded joint, a soldered or brazed joint, a cast joint, a joint working by clamping or pressure (for example, also in the form of two screwed pieces or partially riveted elements), an interlocking joint, a hooking joint, or a combination of at least two of the above-mentioned cord-joining components.
  • the cord-joining component (14) is a clamping joint or a pressure joint, as described later in detail.
  • the cord-joining component (14) is arranged on the first site of the drum (2) according to the invention, in the area of one of the slot-like elbows (12). Depending on the number of slot-like elbows (12) distributed along the circumference of the drum (2), this is the first site (see Fig. 2 ), with respect to the basically circular cross-section of the drum (2), separated from the second side (see Fig. 3 ). In three elbows, the first side is facing the second site continuously at about 120°, in two, four, eight, etc. The elbows (12) are preferably facing continuously at 180°.
  • the cord-joining component (14) is arranged, at least in part (here, with interior side), inside the elbow (12).
  • the cord-joining component (14) in this embodiment is then arranged in a region of the circumference of the main casing part (4a), separate from (preferably exactly opposite to) the extended inserting region (B F ).
  • the cord (8) preferably runs through one of the grooved elbows (10), so that the latter secures the cord (8) in the axial direction (compare with A) of the drum (2) against lateral slippage.
  • Fig. 4 shows a diagrammatic longitudinal view taken across the cord (8) and illustrates further technical details of the cord (8) and the cord-joining component (14).
  • the cord-joining component (14) has at least one first coupling element (14a), which is, or can be, fixed to the first end (8a) of the cord, and at least one second coupling element (14b), which is, or can be, fixed to the second end (8b) of the cord.
  • Each coupling element (14a, 14b) has a cord-joining region (14a1, 14b1) where the corresponding end (8a, 8b) of the cord (8) is inserted.
  • the corresponding cord-joining region (14a1, 14b1) is pressed with the appertaining end (8a or 8b), respectively.
  • the two coupling elements (14a, 14b) are so shaped that they can be inserted into each other.
  • the coupling element (14b) is made in the form of a capsule and has a tubular receiving region (14b3) with a deformation zone (14b2).
  • the coupling element (14a) is shaped like a bolt.
  • the coupling element (14a) has a head (14a2) whose outside diameter is insignificantly smaller than the inside diameter of the receiving region (14b3) of the corresponding capsule-like coupling element (14b), so that the two coupling elements (14a, 14b) can be easily inserted into each other.
  • the head (14a2) is combined with a cylindrical section that extends lengthwise, passing through a step or a projection, whose diameter is smaller than that of the head (14a2) and which forms the cord-joining region (14a1).
  • this region (14a1) can have on its outside circumference for example also several annular protuberances or other suitable pieces for a form-locking joint.
  • the coupling element (14b) has a limiter (16) for the head (14a2) of the coupling element (14a).
  • the cord (8) is prefabricated as a single mounting unit, with a cord-joining component (14) or its separate components, which mounting unit has a predetermined mounting length (L M ).
  • L A is the length of the outside circumference of the main casing part (4a) in the region where the cord (8) is to be located
  • D X is a length of considerable magnitude for the reversible elastic tensing of the cord (8) in a later step.
  • the actual length of the cord (L S ), to which the cord (8) should be cut for making said mounting unit, is somewhat smaller than the mounting length (L M ), since the coupling elements (14a, 14b) themselves have a predetermined length.
  • Fig. 5a shows a diagrammatic longitudinal view taken across the cord (8) or across the mounting unit shown in Fig. 4 in a first, unmounted state, in which the cord (8) loosely encircles the main casing part (4a), which is not shown.
  • Fig. 5b shows a diagrammatic longitudinal view taken across the cord (8) shown in Fig. 4 in a second state, in which it is mounted, and its cord ends (8a, 8b) are firmly joined together with the aid of the cord-joining component (14), and in which the cord (8) encircles the main casing part (4a) in the pretensed state.
  • the head (14a2) of the coupling element (14a) is located a predetermined distance (D X ) in front of the limiter (16).
  • D X a predetermined distance in front of the limiter (16).
  • the cord (8) is tensed until the head (14a2) reaches the limiter (16) (see Fig. 5b ).
  • the receiving region (14b3) similarly serves as a guide for the head (14a2).
  • the tensing can be carried out with a relatively simple tool, applied to both coupling elements (14a, 14b).
  • the second state see Fig.
  • the cord (8) or the reversible elastic mounting unit is then extended to a second predetermined encircling length, which is somewhat greater than the first predetermined encircling length and which corresponds basically to the length of the outside circumference (L A ) of the main casing part (4a).
  • the cord (8) in the mounted state encircles the main casing part (4a) in the pretensed state.
  • the cord-joining component (14) or the combined action of its coupling elements (14a, 14b) and the limiter (16) define the length of the second turn and the pretensing magnitude of the cord (8).
  • the cord-joining component (14) also acts as a cord-tensing element and a safety element.
  • the cord-joining component (14) therefore forms a kind of pressure terminal, in which the two coupling elements (14a, 14b) have a form-locking shape in the pressed state as regards the longitudinal direction of the cord (8).
  • the joining of the cord is therefore ensured in a reliable way, so the cord cannot become detached even during the rapid rotation of the drum (2).
  • Fig. 6 shows a longitudinal diagrammatic view taken across a cord-joining component (18) for the cord (8).
  • This cord-joining component (18) is similar to the cord-joining component (14) shown in Figs. 4, 5a and 5b . Unlike the latter, however, it has two coupling elements (18a, 18b) shaped like the coupling element (14a) of the variant shown in Figs. 4, 5a and 5b .
  • the construction shown in Fig. 6 has a separate capsule (18c) in the middle, with one opening for insertion on the left and one on the right - into which can be inserted the first and second coupling element (18a, 18b) each of which is coupled to an end of the cord (8a, 8b).
  • the capsule in the middle (18c) has an internal separating wall (18c1) whose lateral surfaces act as a limiter (16) for the heads (18a2, 18b2) of the two coupling elements (18a, 18b).
  • the capsule in the middle (18c) therefore acts as a separate limiter for the cord-joining component (18) to which are assigned at least a first coupling element and then a second coupling element (18a, 18b).
  • the application of the coupling elements (18a, 18b) to the capsule in the middle (18c) and with it the joining of the ends of the cord, as well as the tensing of the cord (8) take place in the same way as in the case of the variant shown in Figs. 4, 5a and 5b .
  • the heads (18a2 and 18b2) are drawn together, and the capsule regions (18c2) are pressed over the cord-joining regions (18a1, 18b1) of the coupling elements (18a, 18b), and they surround the heads (18a2, 18b2) in the radial and axial direction.
  • the capsule in the middle (18c) also acts as a tensing and safety element for the cord and the coupling elements (18a, 18b).
  • D X1 and D X2 can be identical or different. As far as possible, the sum of D X1 + D X2 should be equal to the value of D X in the example illustrated in Figs. 4, 5a and 5b in order to be able to obtain relations for the tension in the cord (8) when the latter is in the second state mentioned above.
  • Fig. 7 shows a diagrammatic side view, not drawn to scale, of a drum (2) according to the invention, and specifically a second embodiment.
  • the cord (8) encircles the outside circumference of the main casing part (4a) several times, i.e. in a number of turns ranging from W 1 to W X ,

  • the turns W 1 to W X of the cord (8) can lie at the same angle of tilt and/or at different angles of tilt around the main casing part (4a).
  • Figs. 8a-8c show preferred examples of cord-joining components, which can be used in the type of drum (2) according to the invention, where the cord (8) encircles the main casing part (4a) several times, and its turns extend side by side and/or one over the other (for example in the drum shown in Fig. 7 ).
  • the cord-joining component can be made for example as a flat coupling element operating by clamping or pressure (20) (see Fig. 8a , with deformed regions in the form of folds running in the longitudinal direction, which increase the mechanical strength of the cord-joining component) like a metal band (22) ( Fig.
  • Fig. 9 shows a diagrammatic side view, not drawn to scale, of a drum (2) according to the invention, and specifically a third embodiment.
