Definitions

  • a washing machine comprises a drum containing the laundry, immersed in a tank and a device for driving the drum (or basket) in rotation in this tank.
  • the drum is driven in rotation, particularly during spinning, the mass of irregularly distributed laundry forms an imbalance which causes strong vibrations of the assembly.
  • the tank - basket - drive device assembly is mounted mobile, suspended or placed (or both at the same time) on the machine structure .
  • the vibration damping device according to the invention is fixed on one side to the tank of a washing and / or drying machine and on the other side to an immobile part of the machine and is characterized in that '' it comprises at least three degrees of freedom, a first linear damping means cooperating with second damping means in ro tation comprising an articulation with at least two degrees of freedom.
  • This device thus allows positioning of the plate in all directions of space.
  • the forces on the plates can be directed in all directions and the various friction forces can be dosed independently, this makes it possible to significantly reduce the horizontal components of the forces at the foot of the washing machine.
  • the reduction of vibrations of the whole machine allows a gain in acoustic comfort for the user.
  • the cost price is lower than the device of the tube shock absorbers of the first solution mentioned and its reliability higher.
  • a first example of a device according to the invention and as shown in FIG. 1 comprises a damping means consisting of a spring element, here a fi 1 spring 1 in the shape of a U, the base of which is fixed to the mobile element, not shown. , that is to say the tank, and of which the two ends 2 and 3 of the arms are each mounted articulated on sliding shoes 4 and 5.
  • These shoes 4 and 5 are pressed on either side of the plate 6 by the clamping force of the spring wire 1.
  • These pads are guided on the plate 6 thanks, for example, to the edges 7 and 8 formed by the folding down on one of the faces of the plate 6 which delimits a corridor in which the shoe 4. Only one shoe (shoe 4 in the figure) can be guided, the elastic rigidity of the spring wire 1 guiding the other shoe (shoe 5).
  • This linear depreciation constitutes the first degree of freedom of depreciation achieved by the invention.
  • a second example of an embodiment of the invention is shown in section along the axis of symmetry of the plate 6 in Figure 2a.
  • the spring wire 1 fixed to the mobile or fixed part of the machine has not been shown.
  • the particularity of this second embodiment compared to the first resides in the characteristics of the articulation with at least two degrees of freedom of the device.
  • the plate 6 on which the pads, not shown, rub is articulated on a ball joint 21.
  • This ball joint is fixed to the fixed or mobile part of the machine and comprises a spherical part 22 on which the plate 6 is articulated.
  • plate 6 may have at its end two tabs 23 and 24 which enclose the part spherical 22 of the ball joint 21.
  • the plate 6 is fixed to a spherical part 31 rotating around a first axis 32 and around a second axis not shown, for example, perpendicular to the previous one and to the plane of Figure 3.
  • the spherical part is placed between two jaws 33,34 fixed for example on a base 35 fixed to the fixed or mobile part of the machine.
  • a rod 36 passes through the jaws 33, 34 and the spherical part 31 along the first axis 32.
  • the rod 36 is locked at a first end against a first jaw 33 by means of a crimping washer for example.
  • a spring system 37 is placed for example between a washer fixed to the latter and the second jaw 34 so that the two jaws 33, 34 clamp the spherical part 31.
  • a material 38 with a given coefficient of friction is placed between the jaws 33, 34 and the spherical part 31.
  • Conical openings 39 are made in the spherical part 31 around the rod 36 from the axis of symmetry of the plate 6 of so as to allow rotation of the spherical part 31 around the second axis not shown.
  • the plate 6 can therefore rotate around the two aforementioned axes with a friction force, these two rotations constituting the two degrees of damping in rotation.
  • Figures 1, 2a, 2b and 3 show two possibilities of articulation with at least two degrees of freedom, but it is obvious that a device according to the invention using any other articulation of this type does not depart from the scope of the present invention.
  • one of the devices according to the invention 20 is fixed in the direction (Z), that is to say vertically.
  • the articulation B fixed to the structure of the machine is placed in the plane (z, y) parallel to the ground and the articulation A in the plane (x, z) so that the plate 6 and the rod spring out 1 U-shaped are vertical, that is to say parallel to the axis (Z).
  • the plates 6 will, thanks to the articulations A and B, make it possible to direct the friction forces in the direction of the movements of the tank and this whatever the direction in the space (x, y, z) of its movements.
