    VIBRATION AMORTIGUATION DEVICE AND DOMESTIC APPLIANCE INCLUDING THE VIBRATION AMORTIGUATION DEVICE
    DESCRIPTION
    The present invention refers to a vibration damping device and a household appliance comprising the vibration damping device.
    Through the prior art, household appliances are known for the treatment of garments, such as washing machines, which comprise a washing drum mounted to rotate about a horizontal axis, which can also oscillate in the frame . Vibration damping devices connected to the floor of the frame can be linear dampers, for example, oil dampers, or the like. In these embodiments, two components of the vibration damping device are coaxially aligned in their respective longitudinal axes, and can move towards each other along these longitudinal axes.
    Also, radial vibration damping devices are known, which are vibration damping devices. These usually have two articulated bars, which are joined together. This design is known, for example, from DE 1 842 817 U.
    However, in the case of this type of vibration damping device, situations in which the oscillating system and, in particular, also the washing drum, are exposed to relatively variable oscillations may occur during operation of the domestic appliance. intense and, thus, oscillation amplitudes can occur that undesirably tilt the work orientation of the articulated bars in relative manner to each other. This means that these articulated bars can no longer move in the desired working orientation relative to each other and relative to the washing drum, but are arranged in an unwanted non-working orientation. In such a non-working position of the articulated bars relative to each other, the behavior against the oscillations of the articulated bars is limited and, therefore, the damping effect of the vibration damping device is also limited. In this design, strong unwanted oscillations can then occur in the
    5

    35
    final positions of the articulated bars, which can cause damage to the components. In particular, by such a non-working orientation of the articulated bars, the entire oscillating group also then remains with limited functionality, so that the damping effect is restricted. As a consequence, unwanted imbalances of the washing drum can also occur, so that, here too, a corresponding deterioration can occur.
    The present invention solves the technical problem of providing an improved vibration damping device and, therefore, preventing articulated bars from tilting towards each other in an undesirable manner, and a domestic apparatus for treating garments comprising This vibration damping device.
    This technical problem is solved by a vibration damping device and a household appliance for the treatment of garments comprising a vibration damping device according to the independent claims. In the dependent claims, preferred embodiments of the invention are disclosed.
    A home appliance vibration damping device according to the invention is configured comprising a first articulated bar, which comprises a first end and a second end opposite the first end, and a second articulated bar, comprising a first end and a second end. opposite the first end, where the first end of the second articulated bar is connected to the first end of the first articulated bar by a first joint, where the articulated bars can be moved relative to each other about a first axis of rotation of the first joint; where the second end of the first articulated bar is joined to a frame of the domestic appliance by means of a second articulation defined by a second axis of rotation and the second end of the second articulated bar is joined to a vat of the domestic apparatus by a defined third joint by a third axis of rotation; and the articulated bars are arranged in such a way that their complete rotation around the first axis of rotation is prevented, where, in addition to preventing their complete rotation, the vibration damping device comprises a device limiting the movement of rotation by means of which the movement of rotation of the two bars articulated relative to each other around the first axis of rotation of the first joint is limited such that, the range of rotation movement limited in this way is smaller than the interval in which the rotation

    complete is limited, the articulated bars can only be arranged in a work orientation relative to each other.
    In this way, it is possible to prevent the articulated bars from rotating relative to each other around 360 ° thanks to the construction design, and a greater limitation of the rotation movement of the articulated bars relative to each other is achieved, thereby which avoids an unwanted adjustment and a non-working orientation of the articulated bars.
    The vibration damping device comprises at least one joint that provides resistance to frictional rotation, also called friction joint. In a vibration damping device, the expression "joint that provides resistance to frictional rotation" or "friction joint" includes the concept of a joint in which the friction values during a rotation thereof exceed 10 N, oscillating the values preferably between 20 N and 120 N and, more preferably, between 30 N and 60 N.
    The joint that provides resistance to frictional rotation comprises a bushing that is traversed in the axis of rotation by a bolt fixedly arranged next to at least one lug, so that a friction element is disposed while being clamped between the bushing and the cap screw. Preferably, the bolt is fixedly attached to two lugs preferably arranged in a "U" shaped configuration, one on each side of the bushing, which makes the joint structure more rigid. Another possibility is that the joint that provides frictional rotation resistance comprises a bushing that is traversed on the axis of rotation by a bolt attached to at least one lug, so that a friction element is disposed while being clamped between the bushing and the At least one lug. Preferably, the bolt is attached to two lugs preferably arranged in a "U" shaped configuration, one on each side of the bushing, which makes the joint structure more rigid. The two lugs can pinch the bushing tightly and can have a friction element between the bushing and them. Obviously, the joint that provides resistance to frictional rotation can have the friction element between the bushing and the bolt, and between the bushing and the at least one lug at a time. In this way, the friction surface is increased if necessary.
    The bushing can be arranged at one end of one of the articulated bars, and then the lugs are arranged at one end of the other articulated bar and / or in the vat and / or in the frame, or the bushing can be arranged in the bowl and / or frame and lugs may be arranged at one end of one of the bars

    articulated With this, the articulation that offers frictional resistance to rotation in any of the three, that is, first, second and third articulation, of the vibration damping device can be arranged. The friction element is preferably of a high compression material, in particular, an expanded polyurethane sponge, for example from Cellasto ®.
    In particular, the rotation movement limiting device is configured such that, in the working orientation of the articulated bars, the relative rotation movement between the two articulated bars is limited to a maximum angle of 180 ° relative each. In this way, the advantages mentioned above are improved again.
    In particular, it is envisaged that, in the working orientation of the articulated bars, the relative rotation movement between the two articulated bars is limited to a maximum angle of 180 ° relative to each other. 180 ° is the limitation for the maximum value of the smallest angle defined by two articulated bars. It is clear that two articulated bars create two angles on their axis of rotation, which are conjugate angles. This means that the sum of the two amounts to 360 °. Therefore, when the smallest angle is, for example, 130 °, the largest will be 230 ° (both angles are conjugated). In this way, the inclination of the articulated bars to the non-work orientation is also safely avoided, since this lower angle in an initial position is limited to a maximum value of 180 °.
    In a particular embodiment of the invention, the vibration damping device comprises a rotation movement limiting device, which is a first rotation movement limiting device disposed in the first joint and comprises a rotation movement limiting element, which is arranged at a first end of the second articulated bar, for limiting the rotation movement of the articulated bars relative to each other depending on the rotation position of the two articulated bars, which collides against the first articulated bar , or the limiter of the rotation movement is arranged at a first end of the first articulated bar, for the limitation of the rotation movement of the articulated bars relative to each other depending on the rotation position of the two articulated bars, the which hits the second articulated bar. The limiting element of the rotation movement can be arranged in any part of the articulated bar and can collide with any part of the other articulated bar.

    This limiting element of the rotation movement arranged in one of the two articulated bars collides with the other articulated bar, limiting the movement between both articulated bars around the first articulation of the vibration damping device. This embodiment has the advantage of having a rotational movement limiting device on the articulated bars of the shock absorbing device itself, creating a robust design. The functionality of the rotation movement limiting device is ensured in the vibration damping device itself, and does not depend on the system in which the vibration damping device is to be mounted.
    In a particular embodiment of the invention, in the mounting position in the home appliance, the vibration damping device comprises a rotation movement limiting device, which is a second rotation movement limiting device arranged in the second and / or third articulation, which comprises a limitation element of the rotation movement arranged in the first and / or second articulated bar limiting the rotation around the second and / or third articulation by means of its collision with the frame and / or the tank.
    The vibration damping device of this embodiment has additional alternatives to limit rotation by including a rotation limiting device in the second and / or third joint that offers many alternatives to ensure the correct working orientation of the vibration damping device.
    In this way, it is possible to arrange multiple rotation limiting devices on the vibration damping device. This creates a much safer vibration damping device, which ensures correct working orientation through additional rotational movement limiting devices that act in the event that the first rotation movement limiting device fails or is damaged.
    In a particular embodiment of the invention, the vibration damping device has a rotational movement limiting element protruding from the second end of the first or second bolt-shaped articulated bar, in particular, it is oriented on the longitudinal axis. of the first or second articulated bar in the opposite direction to the second end, so that the rotation movement of the first articulated bar rotating around the second axis of rotation is limited when stopping against the frame, or of the second articulated bar rotating around The third axis of rotation is limited when stopping against the tank.

    The main advantage of this particular embodiment is that the limitation of movement can occur in a simple and economical way by the collision of two parts. The rotational movement limiting element may be integrated in the articulated bar or in the articulated bar receptacle, or it may be an additional part attached to the articulated bar or the frame or the tank. If the limiting element of the rotational movement is an additional part, it can be joined by any known method, for example, glued, welded, screwed, molded, riveted, or injected.
    The rotation of the articulated bars of the vibration damping device can be very simply limited around the second and / or the third joint in order to ensure that the vibration damping device is always operating in the desired working orientation. .
    The limiting element of the rotation movement can also protrude from the frame or the tank so that it collides with any of the articulated bars of the vibration damping device in order to limit the rotation around the second and / or third axis of rotation.
    In a particular embodiment of the invention, the vibration damping device comprises a first articulated bar receptacle that can be attached to the frame, to which the second end of the first articulated bar is attached, and / or the third joint comprises a second receptacle. of articulated bar joined to the tank, to which the second end of the second articulated bar is attached.
    This embodiment has the advantage of a much simpler calibration of the vibration damping device in the event that the friction joint is arranged on the second and / or the third joint. The vibration damping device can be measured and calibrated in the production line of the vibration damping device and can be supplied with the desired friction force.
    In a particular embodiment of the invention, the rotation movement limiting device is a second rotation movement limiting device arranged in the second and / or third joint with a rotation movement limiting element at the second end of a bar articulated, which stops against the articulated bar receptacle for limiting the rotation movement of the articulated bars relative to each other depending on the rotation position of the two articulated bars and / or with a limiting element of the movement of

    30
    rotation in the articulated bar receptacle, which stops against the second end of an articulated bar for limiting the rotation movement of the articulated bars relative to each other depending on the rotation position of the two articulated bars.
    The main advantage of this configuration is that the rotational movement can be limited more easily thanks to the fact that the shock occurs between the articulated bar receptacles and the articulated bars, being easier to design a configuration that ensures the rotation limitation around the axes of rotation.
    An articulated bar receptacle can have different embodiments. One of the preferred embodiments for the articulated bar receptacle is a "U" shaped articulated bar receptacle. The "U" articulated bar receptacle has two lateral lugs and a part that joins both lugs.
    The "U" shaped articulated bar receptacle has the advantage of being a robust and easy to produce articulated rod receptacle.
    In a particular embodiment of the invention, the rotational movement limiting element protrudes from the second end of the first or second bolt articulated bar, in particular, it is oriented on the longitudinal axis of the first or second articulated bar in the opposite direction to the second end, so that the rotation movement of the first or second articulated bar rotating around the second or third axis of rotation is limited when stopping against the articulated bar receptacle.
    In a particular embodiment of the invention, the second rotation movement limiting device comprises at least one rotation movement limiting element, which is configured on at least a first lug of the articulated bar receptacle, to which the first or second articulated bar, and is oriented in the direction of a second lug of the articulated bar receptacle, so that the rotational movement of the first or second articulated bar rotating around the second or third axis of rotation and between the lugs is limited when hitting the limiting element of the rotation movement.
    The second rotation movement limiting device may comprise a rotation movement limiting element arranged in one of the lugs and directed in the opposite direction to it, in the direction towards the opposite lug. This
    5

    30
    Rotational movement limiting element can even join both lugs in order to reinforce the "U" shaped structure.
    The invention also makes reference to a domestic apparatus for the treatment of garments, which comprises a frame in which an oscillating system with a tank is mounted, where the oscillating system comprises at least one vibration damping device that is configured for damping the vibrations of the oscillating system against the frame, and the vibration damping device is a vibration damping device according to any of the claims set forth above.
    In this case, even in the very rare case of strong oscillations, the desired working orientation of the vibration damping device is always achieved and ensured.
    The desired work orientation in the case of a household appliance for the treatment of garments is the orientation in which the first joint is on the nearest side of the side of the nearest frame.
    The invention also refers to a domestic apparatus for the treatment of garments, where the frame comprises an articulated bar receptacle and / or the tank comprises an articulated bar receptacle, where the rotation movement limiting device additionally creates a coding assembly to define the position of the vibration damping device assembly in the articulated bar receptacle.
    If the articulated bar receptacle is included in or is part of the frame and / or the tank, the rotational movement limiting device, which is limiting the movement around the second and / or third axis of rotation in a dynamic situation, helps also to the assembly line worker to assemble the vibration damping device correctly in the domestic appliance. The rotational movement limiting device is also a barrier to prevent the vibration damping device from being mounted in the non-working orientation. The rotational movement limiting device collides with the vibration damping device in the event that the assembly line worker tries to mount it in a position in a non-working orientation, preventing this assembly and ensuring correct assembly. Therefore, it creates this assembly coding for the correct assembly of the vibration damping device in the desired working orientation in the domestic appliance.

    In figure 1, a domestic apparatus 1 for the treatment of garments is shown in a simplified front view, which is in particular a washing machine, although it can also be a washer-dryer. It can be seen that the domestic appliance 1 comprises a frame 2, where, in figure 3, a view of its interior is shown and components present therein can be observed. Here, the domestic appliance 1 comprises an oscillating system 3, which comprises a tank 4 and a washing drum 5. In the washing drum 5, clothes garments 6 are to be disposed as examples, which are to be washed. The washing drum 5 is rotatably mounted around a rotation axis 7 which is perpendicular to the plane of the figure, a drive motor 8, for example, a belt drive motor, can be provided for this purpose.
    In the embodiment, the oscillating system 3 further comprises two springs 9 and 10, whereby the tank 4 and the washing drum 5 are movably mounted on the frame 2, specifically, in the upper area.
    Likewise, a damping arrangement 11 is provided, which comprises in the embodiment at least two vibration damping devices 12 and 13. The tank 4 is supported on this damping arrangement 11. For the damping itself of large amplitudes, dampers are used vibration damping devices 12 and 13.
    The vibration damping device 13 is different from the vibration damping device 12, since it comprises at least one articulated bar receptacle that can be attached to a frame or to a tank. Both offer similar functionality relative to the disclosed invention.
    In Figure 1, vibration damping devices 12 and 13 are shown in their work orientation. In the corresponding continuation of the explanation, reference is made to Figure 2. In this, it can be seen that the vibration damping device 12, 13 comprises a first articulated bar 14 and a second articulated bar 15. The two articulated bars 14 and 15 are separate parts and are each made so that they are rigid in themselves. The first articulated bar 14 is connected by the first joint 16 with the second articulated bar 15 in an articulated manner. The axis of rotation 17 of the first joint 16 is oriented perpendicularly to the plane of the figure. The two articulated bars 14 and 15 can be rotated around the axis of rotation 17, which is oriented perpendicularly to the longitudinal axes A and B. Likewise, the articulated bars 14 and 15 are guided one inside the other in the joint 16, so that the
    5
    10
    fifteen
    twenty
    25
    30
    35
    Rotational movement of the articulated bars 14 and 15 relative to each other is already limited to an interval less than 360 °.
    Likewise, the first articulated bar 14 is articulated together with an articulated bar receptacle 18 by means of a second joint 19, where a rotation axis 20 of this second joint 19 is also oriented perpendicularly to the plane of the figure. The second articulated bar 15 is connected with the tank 4 at its end 15b (figure 1) away from the first articulated bar 14. With a first end 15a, the second articulated bar 15 is connected with the first articulated bar 14 in an articulated manner.
    In this work orientation, the two articulated bars 14 and 15 are oriented with their longitudinal axes A and B at an angle that differs 180 ° relative to each other. Likewise, the first articulated bar 14 is oriented such that it is oriented with an end 14a connected with the second articulated bar 15 directed towards a frame wall 2a adjacent to the vibration damping device 12, 13. This means that, in this work orientation, this first articulated bar 14 is directed with its end 14a in the opposite direction to the opposite vertical frame wall 2b. This is the vertical wall of the frame 2 that is furthest from the vibration damping device 12.
    In this working orientation, the two articulated bars 14 and 15 can move relative to each other, so that the angle a between the longitudinal axes A and B changes correspondingly during the oscillation. As can be seen, the first articulated bar 14 is rotatably mounted and distanced from the floor 21 of the articulated bar receptacle 18. In this working orientation, this end 14a of the first articulated bar 14 is arranged inclined so that it is directed in the opposite direction to the washing drum 5 and also to the tank 4. At the second end 14b of the first articulated bar 14, whereby the first articulated bar 14 is coupled with the second joint 19, a first limiting element of the Rotational movement 22 is formed integrally, which extends away from the second end 14b as a pin or pin. In the embodiment shown, it is provided that this limiting element of the rotation movement 22 is oriented in the direction opposite to the first end 14a and that it extends along the longitudinal axis B.
    By means of this limiting element of the rotation movement 22, the rotation movement of the first articulated bar 14 around the axis of rotation 20 is limited. By this limiting element of the rotation movement 22 is
    5
    10
    fifteen
    twenty
    25
    30
    35
    A component of a rotation limitation device 28 'is configured, whereby, going beyond the avoidance of complete rotation of the articulated bars 14 and 15 as explained above, a defined rotation limitation is configured which limits the movement of rotation in a smaller interval than the interval of avoidance of complete rotation and in which the articulated bars 14, 15 are maintained in a work orientation relative to each other. In particular, this limiting element of the rotation movement 22 is configured and arranged such that the maximum rotational movement around the axis of rotation 20 is possible at an angle less than or equal to an inclination angle. This angle of inclination defines the position of the rotational movement of the first articulated bar 14 from which the articulated bars 14, 15 would be inclined from the work orientation to a non-work orientation. In this non-work orientation, the first articulated bar 14 would then be oriented towards the inside of the frame 2, as indicated in Figure 4 by way of example. In this non-work orientation shown in Figure 4, the damping effect of this vibration damping device 12 is restricted. By providing at least the first limiting element of the rotation movement 22, this inclination of the articulated bars 14 and 15 of the work orientation shown in Figure 2 to the non-work orientation shown in Figure 4 can be avoided.
    In figure 3, the embodiment according to figure 2 is shown, where the articulated bars 15 and 14 are shown in their working orientation, in a relative position relative to each other that differs from that of figure 2, in which angle a is greater. In Figure 3, another position of the articulated bars 14 and 15 has been reached relative to each other, which is now the limited end position, since the limiting element of the rotation movement 22 has stopped against the floor 21 and therefore, it is no longer possible to continue the rotation movement clockwise of the articulated bar 14 around the axis of rotation 20.
    In Figure 5, an embodiment of a first articulated bar 14 is shown in perspective view. With two lugs 14c and 14d, the first articulated bar 14 is grasped by its other end 14b.
    In figure 6, another embodiment is shown in a perspective view, in which, unlike in the explanations made so far, a limiting element of the rotation movement 23 is configured. Therefore, in this form of embodiment, the limiter of the rotation movement 22 is not present next to the first articulated bar 14. The limitation of the movement of
    5
    10
    fifteen
    twenty
    25
    30
    rotation around the axis of rotation 20 is achieved by these limiting elements of the rotation movement 23. Here, the limiting element of the rotation movement 23 is integrally formed on a lug 25, 26 of this articulated bar receptacle 18 and is folded in the direction of the opposite lug 25, 26 of this articulated bar receptacle 18. Thus, the rotational movement limiting element 23 extends in a rotation path that is traversed by the first articulated bar 14 rotating around the axis of rotation 20, and also serves here as a corresponding stop to limit the rotation movement clockwise of the first articulated bar 14. In particular, it is envisaged that, by means of the limiting element of the rotation movement 22 or at least one limiting element of the rotation movement 23, the angular position between the two articulated bars 14 and 15 is limited in its orientation n work to a maximum of 180 ° relative to each other. Therefore, the longitudinal axes A and B of these two articulated bars 14 and 15 are displaced by a maximum of 180 ° relative to each other in the work orientation. In this case, the articulated bar receptacle 18 is another piece of the vibration damping device 13, but it could be a part integrated in the frame 2, as shown in Figure 7, or it could be an additional piece that joined the vibration damping device 12 and the frame 2.
    Figure 6 shows the connection of the vibration damping device 13 to the lower side of the frame 2, but a similar configuration is possible to join the vibration damping device 13 to the side side of the frame 2, even to the front / rear side of the frame 2.
    A similar configuration is possible for joining the vibration damping device 12, 13 to the tank 4 at the top. Therefore, the limiting element of the rotation movement 23 can limit the rotation movement in the counterclockwise direction of the second articulated bar 15 around the third axis of rotation 35 of the third joint 32.
    In figure 7, another embodiment is shown, in which the components according to figure 6 are shown. In this embodiment, the articulated bar receptacle 18 is integrated in a part of a frame 2, and the lugs 25 and 26 have been created by die cutting and bending. In this embodiment, a vibration damping device 12 is used without any additional parts as an articulated bar receptacle 18.

    In Fig. 8, an embodiment is shown in which a combination of the limiting elements of the rotation movement is realized, and both the limiting element of the rotation movement 22 and the limiting element of the rotation movement 23 are present. The articulated bar receptacle 18 is configured here by way of example in accordance with the embodiment of Figure 6.
    In figure 9, another embodiment is shown, in which, preferably, the limiting elements of the rotation movement 22 and 23 are also present, although the articulated bar receptacle 18, unlike in figure 8, is made in accordance with the embodiment of figure 7.
    In figure 10, another embodiment of the vibration damping device 12, 13 is shown in a front view. In this embodiment, the first rotation movement limiting device 28 comprises a rotation movement limiting element 29, which is configured at the first end 15a of the second articulated bar 15. Another limiting element of the rotation movement 30 is configured next to the first articulated bar 14. In the position of the articulated bars 14 and 15 relative to each other shown In Figure 10, these two limiting elements of the separate rotation movement 29 and 30 are not yet in contact. However, in Figure 11, these are in contact and the continuation of the rotation clockwise of the articulated bars 14 and 15 relative to each other is prevented.
    Also in this embodiment, the rotation movement of the articulated bars 14 and 15 relative to each other is limited to a range less than or equal to 180 °. Here, the angle a is less than or equal to 180 °. In this way, the inclination angle is given.
    In both positions, as shown in Figures 10 and 11, the articulated bars 14 and 15 are in a work orientation.
    Additionally or alternatively, the second end 15b of the articulated bar 15 next to a third joint 32 (see Figure 1) can be articulatedly connected with a component of the domestic appliance 1, in particular, of the oscillating system 3. The component is the tank 4. At this end 15b and / or on the tank 4 a limiting element of the rotation movement 22, 23 can be configured. Thus, the rotation movement of the articulated bar 15 relative to
    this component is limited and, thus, is the rotational movement of the articulated bars 14 and 15 relative to each other.
