    VIBRATION DAMPING DEVICE, ELECTRICAL APPLIANCE AND MANUFACTURING PROCEDURE FOR
    SUCH DEVICE
    DESCRIPTION
    OBJECT OF THE INVENTION
    The present invention is directed to a radial type vibration damping device for damping the oscillation that takes place in an oscillating element, being particularly suitable for damping the vibrations of the washing tank of a washing machine or dryer.
    BACKGROUND OF THE INVENTION
    Document AT218995 shows a vibration damping device for oscillation in a washing machine. This device makes it possible to dampen the oscillation generated by the drum of the washing machine, by means of a device comprising a support element, an articulation piece and a rotating joint. This configuration is intended to achieve a way of damping the oscillations by means of a rotary damping device. However, this configuration is conditioned by the mechanical and thermal properties of the parts that compose it, as well as by the friction values that can be predetermined in each of the possible friction joints.
    DESCRIPTION OF THE INVENTION
    The present invention proposes a solution to this problem by means of a damping device, a manufacturing process, and a washer or dryer machine. Preferred embodiments of the invention are defined in the dependent claims.
    A first inventive aspect of the invention relates to a vibration damping device for a washing tank of a washing machine or dryer which also comprises a housing. Said device comprises a first articulation piece, with a first end and a second end, the first end of the first articulation piece being provided to be joined in an articulated manner to the reservoir of

    washed by means of a first joint that allows the rotation around a first axis of rotation, a second articulation piece, with a first end and a second end, the first end of the second articulation piece being articulated jointly to the second end of the first articulation piece, by means of a second articulation that allows the rotation around a second axis of rotation, and the second end of the second articulation piece being provided to join the housing by means of a third articulation that It allows the rotation around a third axis of rotation, in which the first joint, the second joint and / or the third joint is a joint that offers resistance to frictional rotation that has a sleeve which in the axis of rotation is traversed by a bolt can be connected to at least one lug, so that a friction element can be arranged between the bushing and the at least one lug, in that the friction element is integrally connected to one of the bushing and lug.
    In a radial damping device, it is considered a joint that offers resistance to friction rotation, or friction joint, that in which the friction values during the rotation thereof exceed 10 N, being preferably between 20 N and 120 N and more preferably between 30 N and 60 N.
    Having the friction element fixed in solidarity, either to the lug or to the bush, offers the advantage of being able to predetermine the friction forces in the friction joint through parameters such as the friction surface or the friction coefficient of the materials, obtaining controllable values in the desired operating ranges in front of a joint in which the friction element is located freely between both elements (the lug and the bushing), in which case it is not possible to control the friction forces caused by said joints due to the uncontrolled relative rotation between the elements. When the friction element is integral with the lug, it exerts friction against the ferrule while when the friction element is integral with the ferrule, it exerts frictional force against the lug.
    Its use in devices such as washing machines or dryers allows to limit the movement of elements that generate oscillations due mainly to the high inertia that occur in phases of acceleration and deceleration of the drum inside the washing tank together with the non-uniformity in the distribution of the laundry load inside the wash tank and the diameter of said laundry tanks in order to increase the amount of laundry load in a single wash cycle.

    The articulation that offers resistance to friction rotation comprises a bushing which, in the rotation axis, is crossed by a bolt connected to at least one lug, so that a friction element is arranged between the gland and the at least one lug. Preferably the bolt is connected to two lugs preferably arranged in a U shape on each side of the bushing which makes the structure of the joint more rigid. The two lugs can pinch the bushing tightly and both can have a friction element between the bushing and the bushing.
    The bolt is connected to the at least one lug. This connection can be made by different joining means such as threading, by nut, by welding, using adhesive means or similar fixing means.
    The bushing can be arranged at one end of one of the articulation pieces and then the lugs are arranged at one end of the other articulation piece and / or in the washing tank and / or in the housing. Or, the bushing can be arranged in the washing tank and / or in the housing and the lugs are arranged at one end of one of the articulation pieces. With this, the articulation that offers frictional resistance to rotation in any of the three, first, second and third articulation can be arranged. The friction element is preferably of a high compression material, in particular an expanded polyurethane sponge, for example from Cellasto ®.
    In a particular embodiment the friction element is attached to the bushing or to the lug by shape drag. This form of union has the advantage of being very cheap and very easy to industrialize. The simplest and easiest way to industrialize is to make a housing in the lug or the bushing where the drag friction element is fixed without the possibility of movement, thus not needing any additional fixing element.
    Shape drag is the simplest way to join the friction element either to the lug, or to the bushing, however if necessary and if the joint requires it, additional fixing means can be added between the friction element and the component where it is fixed (lug or bushing) such as adhesive means, or other equivalent fixing means.

    In a particular embodiment, the friction element is disk-shaped with a hole pierceable by the bolt. In the friction joint there is a bolt-like element that performs the function of clamping the bushing of one of the joints against the at least one lug of the other joint. The advantage of this embodiment is that the friction element is already prepared to be able to be pierced by the bolt and in addition the fact of having a disk shape and therefore being substantially flat facilitates the accommodation, the clamping and the fixing thereof, either either to the lug, or to the bushing, in the friction joint.
    In a particular embodiment the perimeter of the friction element is polygonal. The advantage of this embodiment is that by arranging the friction element of edges and angles it is easier to immobilize it by taking advantage of its own geometry in the lug or the bushing without the need of any additional attachment element to the lug or the bushing in the articulation of friction. In addition, not requiring additional elements reduces the cost and makes the process of industrialization much easier.
    In a particular embodiment, the perimeter of the friction element is square, triangular or hexagonal. The friction element can be produced industrially in the form of a plate from which the friction elements with the geometry and sizes suitable for friction joints are cut by cutting. The advantage of using geometries such as the square, the triangle or the hexagon is that you can take advantage of almost the entire plate from which the friction element is obtained by reducing the amount of material that cannot be used and reducing the total costs and cushions of the damping device.
    Preferred are those embodiments in which both the lug and the bushing are made of thermoconductive material, but in case the lug or the gland are not made of thermally conductive material it is advantageous to fix the friction element in the element, either the lug or the bushing, made of non-thermoconductive material and that is the other element, the bushing or the lug respectively, made of thermoconducting material which has relative movement in front of the friction element and rubs against it. This configuration offers the advantage of providing a heat evacuation path generated by the friction that occurs in the joint that offers resistance to friction rotation avoiding the risk of overheating due to a prolonged operation over time of said device that could damage or even destroy the friction element of

    same.
    By thermoconductive material is meant a material having a thermal conductivity greater than 5 W / (mK), preferably greater than 10 W / (mK) and more preferably greater than 40 W / (m-K).
    In a particular embodiment, the thermoconductive material is a metal such as steel, aluminum, zinc, copper, zamak, stainless steel, bronze, brass and / or titanium or alloys of the foregoing or of any material having a suitable thermal conductivity.
    In a particular embodiment, the first articulation piece and / or the second articulation piece is made of a metallic material and comprises the integrated bushing. This device offers the advantage of providing an articulation piece with better mechanical properties, allowing the device to withstand greater loads and decrease the volume of the elements that make up the device. The use of this damping system in a washer or dryer machine frees up space inside it that can be used for different uses. Furthermore, the fact that the bushing is integrated in one of the articulation pieces offers the advantage of reducing the number of parts of the damping device as well as reducing the costs thereof and the number of operations necessary for the manufacture of the damping device.
    In a particular embodiment, the articulation piece made of metallic material comprises the at least one integrated lug. The integration of the lug into one of the articulation pieces offers the advantage of reducing the number of parts of the damping device as well as reducing the costs thereof and the number of operations necessary for the manufacture of the damping device.
    In a particular embodiment, the second articulation piece is made of plastic material with the integrated bushing which, in the third joint, can be connected to the at least one metal material lug of the washer or dryer machine housing and the element of friction is draggedly attached to the bushing. The advantage of this configuration is that the entire surface of the housing can be used as a radiating element to dissipate the heat generated in the friction joint. .

    In a particular embodiment, the second joint is a joint that offers resistance to frictional rotation where the bolt connects at least one ear with the predetermined force to the bushing with the friction element between them. This embodiment offers the advantage of making it easier to determine the friction force of the damping device in the same manufacturing line as it can be verified if the device exits with the desired friction force and can even be adjusted if necessary. in the manufacturing facility itself.
    In a particular embodiment, the first and / or third joint is a joint that offers resistance to frictional rotation where the bolt connects at least one lug with the predetermined force to the bushing with the friction element disposed between them and the At least one lug is attached to a lug holder and the lug bracket is fixed to the housing or the washing tank. This embodiment offers the advantage of a much simpler determination or setting of the nominal friction force of the damping device. The damping device can exit the manufacturing line with a fixed nominal friction force. This friction force can be measured and verified in the manufacturing line itself and adjusted, if necessary, to an objective value that is the nominal value at which you want to work. This is not easily achievable in the case where the adjustment through the bolt has to be made when mounting the damping device on the oscillating element in which it will work.
    In a second inventive aspect of the invention, it relates to a method of manufacturing a vibration damping device with at least one friction joint that is manufactured following the steps of arranging at least one friction element between the bushing and a lug, joining the friction element to the bushing or to the lug, cross the previous assembly with a bolt pressing the lug against the bushing with a preset pressure.
    The advantage of such a procedure is that it is possible to preset the friction force in the manufacturing line of the damping device itself. In addition to prefixing this friction force, quality control and verification of the same can be done, which ensures the production process of the damping device.
    Said friction joint can be fixed in the case of washing machines or dryers on any of the walls of the housing and / or in the washing tank.

    A third inventive aspect of the invention relates to a washer or dryer machine comprising at least one vibration damping device according to the first inventive aspect.
    The vibration damping devices may be fixed to the sides of the housing, or be fixed to the bottom of the housing or they may be fixed in parallel to the suspension elements at the top or bottom of the wash tank. Said washer or dryer machine may contain a plurality of damping devices located on one or both sides of the wash tank.

    DETAILED EXHIBITION OF THE INVENTION
    Figure 1 shows a particular embodiment of a vibration damping device 1 according to the invention in a use situation, installed in a washing machine or dryer 44. In this figure the following elements, which are part of this damping device, are observed. of vibrations 1:
    - A first articulation piece 2, with a first end 21 and a second end 22. The first end 21 of the first articulation piece 2 is connected in an articulated manner to the washing tank 10, by means of a first articulation 4 which allows the rotation around a first axis of rotation.
    - A second articulation piece 3, with a first end 31 and a second end 32. The first end 31 of the second articulation piece 3 is articulated to the second end 22 of the first articulation piece 2, by means of a second joint 5 that allows the rotation around a second axis of rotation, and the second end 32 of the second joint piece 3 is connected to the housing 11 by means of a third joint 6 which allows the rotation around a third axis rotation.
    In this particular example of a damping device 1 of the invention, the first articulation piece 2 and the second articulation piece 3 are made of a metallic material. In other embodiments, only one of the first articulation piece 2 and the second articulation piece 3 is a metal part.

    In this particular example, both the joint between the first end 21 of the first articulation piece 2 and the reservoir 10 and the junction between the second end 32 of the second articulation piece 3 and the housing 11 are articulations provided by means of two pieces of plastic that pass through holes comprised at the ends of the pieces to be joined, said plastic pieces having stops at their ends intended to prevent the plastic parts from leaving the holes.
    In this particular embodiment shown in Figure 1 the second joint 5 is the joint that offers resistance to frictional rotation. This joint comprises a bushing 7 integrated in the first end 31 of the second articulation piece 3, which in the axis of rotation is crossed by a bolt 8 integral with the lugs 12, so that between the bushing 7 and the lugs 12 is disposed a friction element 9 locked. The friction element 9 opposes the rotation between said elements. The friction element 9 must be integral with the bushing 7 so that friction is carried out on the lugs 12 or with the solidarity 12 with the lugs 12 for friction to occur in the sleeve 7.
    Figure 2 shows the detail of the second joint 5 of Figure 1 which is a joint that offers resistance to frictional rotation. This second joint 5 comprises a bushing 7 corresponding to the first end 31 of the second articulation piece 3 which in the rotation axis is crossed by a bolt 8 connected to the lugs 12 located at the second end 22 of the first articulation piece 2 , so that a friction element 9 is disposed between the bushing 7 and the lugs 12.
    Figure 3 shows a friction joint variant, in which the third joint 6 is the joint that offers resistance to frictional rotation. In this case, this third joint 6 comprises lugs 12 arranged fixed to the housing 11 and a bushing 7 corresponding to the second end 32 of the second articulation piece 3 which in the rotation axis is crossed by a bolt 8 connected to the lugs. 12, so that a friction element is arranged between the bushing 7 and the lugs 12
    9. This is an alternative configuration to that presented in Figure 2, the general operation of the system being the same except that the joint that offers resistance to frictional rotation is in this case the third joint 6 and in Figure 2 is the second joint 5 which offers resistance to frictional rotation.

    In order to increase friction if necessary, it is provided that the friction element between bushing and bolt and between bushing and lug can be arranged at the same time. In this case, the friction element can be made in one piece.
    Figure 4 shows a perspective view of the third joint 6 and the second joint piece 3. In said figure the third joint 6 is a joint that offers resistance to frictional rotation. The second articulation piece 3 is observed with a bushing 7 integrated in each of its ends 31, 32. The bushing 7 is trapped by the lugs 12. The lugs 12 are in this case integral with the lugs holder 20. Both the bushing 7 as the lugs 12 are crossed by a bolt 8 and also between the lugs 12 and the bushing 7 the friction elements 9 which in this case have a hexagonal perimeter are trapped, are substantially flat and have a through hole in the center to be able to be through the bolt 8. The lugs could be fixed to the lugs holder 20 through joining elements such as rivet screws, or by processes such as bonding, welding or equivalent. This construction allows to fix the friction joint of the damping device 1 at any point of the oscillating element to be damped. In the case, for example, of washing machines, the lug support 20 can be fixed at any point of the housing 11 or of the washing tank 10.
    Figure 5 shows a section of a particular embodiment of a third joint 6 and of the second joint piece 3 that joins said third joint 6.. It is observed how the bushing 7 integrated in the second end 32 of the second articulation piece 3 is clamped between the lugs 12 integrated in this case in the lugs holder 20. Both the lugs 12 and the bushing 7 are pierced by the bolt 8 In this case, the friction element 9 has a disk shape and is partially housed in the housing 13 of the bushing 7 of the second articulation piece 3. It can also be seen in Figure 5 that in this case the friction joint 6 It has 2 disk-shaped friction elements 9, one on each side of the bushing 7. The friction element 9 could also be fully housed in the housing 13 of the bushing 7.
    To increase the friction surface the friction element 9 can be located both between the lugs 12 and the bushing 7 (as shown in Figure 5) as well as between the bushing 7 and the bolt 8. The friction element 9 can be in that case in one piece to reduce the assembly costs of the damping device 1 or they can be several independent friction elements. .

    Figure 6 shows an exploded view of a friction joint according to the invention. In this case the third joint 6 is the joint that offers resistance to frictional rotation. The second articulation piece 3 has a bushing 7 integrated in its second end 32. Said bushing 7 has a housing 13 for fixing the friction element 9. The friction element 9 has a hexagonal perimeter intended to be fixed by dragging in the housing 13 of the bushing 7 of the second end 32 of the second articulation piece 3 exerting frictional resistance to rotation in this case against the lug 12. The friction element 9 also has a circular through hole in its center to be pierced by the bolt 8. Bolt 8 passes through both lugs 12, as well as bushing 7 and friction elements 9 and is integral with lugs 12. Lugs 12 are integrated in lugs holder 20.
    Figure 6 is representative of the claimed manufacturing process. A damping device 1 can be manufactured through a lug holder 20 which includes two lugs 12 substantially parallel between which the bushing 7 of the second end 32 of the second articulation piece 3 can be housed. The bushing 7 has a housing 13 in each of its sides where the friction element 9 is housed by dragging. Subsequently, the lugs 12 clamp the bushing 7 by the force exerted by the bolt 8.
    Figure 7 shows a side view of a particular embodiment of second articulation piece 3 according to the invention. In it, the bushing 7 integrated in both the first end 31 and the second end 32 can be seen in more detail. The bushing 7 of the second end 32 also contains a hexagonal perimeter housing 13 to facilitate the drag-in housing of an element. of friction 9 with hexagonal perimeter too. In this case, a rib is also seen to reinforce the connection between the inner and outer part of the bushing 7. This part could also be solid instead of ribbed in another particular embodiment.
    Figure 8 shows a pattern of a particular embodiment of a hexagonal perimeter of a friction element 9. It is observed how the friction element can be manufactured in substantially flat sheets and hence the friction elements 9 can be cut. The hexagonal perimeter allows maximum use of the material to make the friction elements 9 thereby reducing the scrap resulting in a reduction
    of the price of the friction element 9 and the damping device 1 therefore.
    Figure 9 shows a possible configuration of washer or dryer machine 44 containing at least one vibration damping device according to the invention. In this particular example, a wash tank 10 is shown comprising
    a drum 28 which is driven by a motor 25 that transmits movement to the drum through a pulley mechanism 29 integral with the drum 28 and connected to the driving element by a belt 27. Said washing tank is attached to the housing 11 by suspension elements 17 and by two vibration damping devices 1 according to the invention. As shown in Figure 9, the vibration damping devices 1 are fixed to the sides of the housing 11 but could be fixed to the bottom of the housing 11 or could be fixed in parallel to the suspension elements 17 in the part upper or lower wash tank 10.
    A preferred embodiment comprises three damping devices 1 preferably located two of them on one side of the wash tank 10 and a third on the other
    side of said wash tank 10.
    Four damping devices 1 preferably located two on each side of the washing tank 10 can also be arranged.
