Definitions

  • the invention relates to an oscillatory support for drum washing machines according to the preamble of claim 1.
  • an elastic support in which an elastic body is arranged above and below the base plate at a distance from the strut axis, two aligned elastic bodies being connected to one another via clamping bolts, and to the Clamping bolts are attached to the top and bottom plates, with the lower end of the shock absorber screwed onto the upper plate.
  • this elastic support has proven extremely successful.
  • This known support has the disadvantage that, on the one hand, it is very complex and, on the other hand, the rubber part does not exert sufficient restoring forces on the strut when the strut is inclined.
  • the dome part and the spherical dome-shaped recess only have the function of a friction damper.
  • the invention has for its object to provide a support of the generic type, which is simple in construction and easy to assemble and has good vibration and damping properties.
  • the assembly can be carried out in a simple manner, since the shock absorber can only be inserted by simply pushing it in, ie by means of a plug connection. to be connected to the base plate on the one hand and the washing unit on the other. No further manipulations are required.
  • the construction of these parts is correspondingly simple.
  • a damping, elastic plug connection between the shock absorber and base plate is achieved in a particularly simple manner, as a result of which restoring forces are at the foot of the shock absorber, ie directly between the base plate and shock absorber. attack.
  • Claim 4 specifies a particularly simple receptacle for the vibration and damping elements.
  • the elasticity and damping properties of the vibration and damping elements are not only in the case of deflections of the shock absorber, but also when compressive forces occur, i.e. exploited when moving the shock absorber, each over the full height of the entire vibration and damping element.
  • the measures according to claim 6 ensure that, on the one hand, the pin can penetrate the entire length of the respective vibration and damping element, that is to say is optimally guided and held, but that, on the other hand, compressions of the vibration and damping elements are possible.
  • the measures according to claim 7 ensure that, to a limited extent, tensile forces from the articulations can be taken, although it is purely plug connections.
  • the measures according to claim 8 ensure that pitching or wobbling vibrations are largely suppressed, while unbalanced vibrations can develop freely - albeit damped - when passing through the critical speed.
  • a drum washing machine has a washing unit 1, which is supported by spring struts 2 against a base frame or a base plate 4 standing on the floor 3.
  • the washing unit 1 has a tub 5, in which a washing drum 8 is arranged, which can be driven about a horizontal axis of rotation 6 by a drive motor 7 flanged to the tub 5.
  • the input and removal of laundry into the washing drum 8 takes place through a flap lo arranged on an end face 9 of the tub 5.
  • the transmission of the drive from the drive motor 7 to the washing drum 8 takes place in the usual way by means of a V-belt drive 11.
  • the struts 2 each have a cylindrical tube 12, in which a plunger 13 is guided coaxially.
  • a guide piston 14 is formed, which can be provided with annular recesses 15 in which friction elements 16 are arranged.
  • the plunger 13 and the guide piston 14 are injection-molded in one piece from plastic.
  • the friction elements 16 can consist of foamed, closed-cell polyurethane.
  • a prestressed helical compression spring 18 is arranged between the guide piston 14 and the bottom 17 of the tube 12.
  • the tube 12 is provided at its tappet outlet end with an inwardly drawn edge 19 which radially overlaps the guide piston 14, so that the tappet 13 cannot be pulled out of the tube 12 unintentionally.
  • the strut 2 shown is a so-called damped strut. If the friction elements 16 are not present, the shock absorber is undamped. Both types of struts - as far as they are described up to here - are generally known and commercially available (see DE-OS 25 34 65o corresponding to GB-PS 1 52o 383).
  • a flange-like, thrust washer-shaped thrust bearing 2o is attached, from which in turn a cylindrical pin 22 extends coaxially to the central longitudinal axis 21 of the spring strut 2.
  • a thrust bearing 23 is also formed, from which a corresponding pin 24 extends upwards coaxially to the longitudinal axis 21.
  • a support element 25 is attached to the base plate 4 for each strut 2, which essentially consists of a support sleeve 26 which is open at the top and extends along the longitudinal axis 21.
  • the support sleeve has in its base 27 a through opening 28 concentric with the longitudinal axis 21, the diameter of which is in any case larger than the diameter of the pin 22.
  • a support element 29 is also attached to the tub 5 for each strut 2, which has a support sleeve 3o which is of identical design with the support sleeve 26 and which is open at the bottom.
  • the bottom 31 of this support sleeve 3o is thus also provided with a passage opening 32, the diameter of which is larger than the diameter of the pin 24.
  • the support sleeves 26 and 3o have - as can be seen from FIG. 4 - an approximately rectangular cross section, whereby - as in the present case - this cross section is formed by a circle which is formed by two mutually parallel and symmetrically arranged secants.
  • the respective (longer) main axis 33 extends perpendicular to the longitudinal axis 21 and perpendicular to the axis of rotation 6 of the washing drum 8.
  • the minor secondary axis 34 also extends perpendicular to the longitudinal axis 21 and parallel to the axis of rotation 6.
  • rubber vibration and damping elements 35, 36 are arranged, the cross-section of which corresponds to the cross section of the support sleeves 26, 3o, and each around a section a in the direction of the longitudinal axis 21 over the respective edge 37, 38 of the corresponding support sleeve 26, 3o protrude.
  • Each element 35, 36 has a cylindrical recess 39, 40 adapted to the respective pin 22, 24, into which the corresponding pin 22 or 24 is fitted with a press-friction fit. In the relaxed state, the diameter of the recess 39, 40 is therefore slightly smaller than the diameter of the pin 22 or 24. The pin 22 or 24 penetrate the elements 35 or 36 approximately to their full length.
  • the elements 35, 36 is also seated with a press-friction seat in the respective supporting sleeve 26 and 3 0th
  • the washing unit 1 can thus swing out relatively far in the vertical according to the directional arrow 41 and in the horizontal perpendicular to the axis of rotation 6 according to the directional arrow 43.
  • the vibration and damping elements 35, 36 also serve as suspension elements and as damping elements with respect to the vertical vibration. Slipping out of the pins 22 and 24 from the associated elements 35 and 36 is out of the question due to the described press-friction fit, especially since the spring struts 2 are dimensioned in such a way that a stop of the guide piston 14 on the edge 19 also beneath extreme operating conditions does not occur.
  • the embodiment according to FIG. 5 differs only in that the spring strut 2 'is articulated at its upper end in a non-elastic but damping manner on the support element 29' of the tub 5.
  • the plunger 13 'of the spring strut 2 has a ball 45 instead of the pin 24, which is connected to the plunger 13' via an intermediate pin 46.
  • An abutment 47 is fixed on the support element 29 'by means of a locking ring 48.
  • This abutment 47 has a spherical segment-shaped recess 49 whose inner periphery extending over more than 18 0 °, namely preferably above 22 0 ° to 24 ° 0.
  • the inside diameter of this recess corresponds approximately to the diameter of the ball 45.
  • this recess 49 has an insertion inclined surface 51 towards its lower opening 50 so that - since the abutment 47 consists of elastically deformable plastic - the ball 45 through the Opening 5o can be snapped into the abutment 47 with elastic expansion.
  • the ball 45 polyamides are considered, as are commercially available.
  • the mechanism of action in this embodiment is in principle the same as in the embodiment with the shock absorber according to FIGS. 3 and 4. The difference is that there are no restoring forces in the upper linkage. but only vibrations in the horizontal direction according to the directional arrows 43 and 44 damping forces.
  • Both versions are a pure plug connection, in which either the pin 22 or 24 is inserted into the recesses 39 or 40 or the ball 45 into the recess 49.
  • the vibration and damping elements 35, 36 are designed to be relatively long.
  • the construction shown thus enables particularly good vibration and damping also in the direction of the central longitudinal axis 21.
