Definitions

  • the present invention relates to a support structure for the washing tub of a washing machine.
  • the washing tub is connected flexibly to the frame of the machine itself by means of springs or shock absorbers, or by means of a combination of springs and shock absorbers, so as to be suspended.
  • Fixed masses are also provided, integral with the washing tub and acting as counterweights, distributed in such a way as to balance the machine, above all during the centrifugation phase.
  • Another known solution provides a support axle or cradle in sheet metal rigidly connected to the washing tub, a cradle which is then connected flexibly to the frame by means of shock absorbers.
  • the masses acting as counterweights are mounted, by means of bolts, to the support cradle, forming in any case parts which are separate from the cradle itself.
  • the object of the present invention is that of providing a support structure for the washing tub of a washing machine which does not require the assembly of separate parts with counterweight functions.
  • a support structure for the washing tub of a washing machine comprising a support cradle for the washing tub, integral with the latter and connected flexibly to a frame of the washing machine, characterised in that said support cradle is shaped so as to comprise parts of considerable mass, suitable for acting as balancing counterweights.
  • FIGS 1 and 2 show a washing machine of the so-called top-loader type.
  • Such a machine comprises, in a manner in itself known, an external framework 1 enclosing a washing tub 2, inside whereof a loading drum 3 is mounted freely rotatably.
  • the washing tub 2 is attached by means of screws 4, and hence rigidly, to a pair of arched brackets 30 in sheet metal, which are in turn attached by means of screws 5 to a support cradle 6.
  • the brackets 30 are in turn provided with a circumferential series of holes 10 coinciding with the holes 8 of the flanges 7, and a central hole 11 for the passage of the hub 9.
  • a reinforcement of a ball bearing 12 is keyed inside each hub 9, the other reinforcement whereof being keyed to a hub 13 integral with the loading drum 3. In this way the drum 3 is supported, freely rotating, inside the tub 2 (Fig. 2).
  • the support cradle 6, shown in Figures 3-6, has a substantially rectangular plan (Fig. 3) and an upper profile raised at the two smaller sides, and lowered in the centre, to allow housing of the washing tub 2, without increasing the overall dimensions (Fig. 4).
  • the support cradles are made by means of bent sheets, and counterweights in concrete or cast iron are mounted thereon by screws to perform balancing functions.
  • the cradle 6 is made in cast iron or concrete, by means of moulds, and is shaped in such a way as to have parts of significant mass which act as counterweights.
  • the support cradle 6 has two parts 14 and 15, placed along the two smaller sides of the cradle 6, where the thickness of the material constituting the cradle 6 itself is considerably greater compared to the remaining parts of the cradle 6. These parts 14 and 15, positioned opposite to a transverse axis of the cradle 6, form blocks of material which act as counterweights.
  • the block 14 is distributed in an essentially symmetrical manner in relation to a longitudinal axis of the cradle 6, and two undercuts of material 16 and 17 are provided at its sides, at which two respective holes 18 (Figs. 3 and 6) are formed for assembly of the rod of two respective telescopic shock absorbers 19 (Figs. 1 and 2), whose cylinder is attached below to the frame 1.
  • two respective, smaller, holes 20 are provided for assembly by means of screws of the brackets 30.
  • a hole 21 is provided for assembly of the rod of an additional telescopic shock absorber 22, also attached below to the frame 1.
  • an additional telescopic shock absorber 22 is attached below to the frame 1.
  • two holes similar to the holes 20 are formed, likewise for assembly of the brackets 3.
  • a hole 23 is also formed in the lowered part of the cradle 6 for connection of a drain pipe (not shown in the drawings) to the tub 2, and four holes 25 for the attachment, below the cradle 6, of a pair of flanges 26 which support, by screws, an electric motor 27 for moving the drum 3.
  • the support cradle 6 in addition to being produced as mentioned previously in cast iron or concrete, can usefully be made according to a patented system, comprising a shell acting as an external casing in plastic for a solidified compound injected in the fluid state in said shell.
  • shock absorbers 19 and 22 which in the example shown connect the cradle 6 flexibly to the base of the frame 1, could also be of a different number, and could be connected to the frame 1 above, instead of below, the cradle 6.
