Definitions

  • ABSTRACT The present invention relates to a roller bearing device for a small linen washing machine.
  • the device is constituted by a flat ring provided at its periphery with a plurality of rollers and interposed between the linen agitating wheel and a removable plate mounted at the tub bottom of the machine.
  • Circular guiding grooves for the rollers are provided in the mutually confronting faces of the plate and the wheel, the latter thus resting upon the rollers during its rotation in the tub of the machine, so as to prevent friction between the said agitating wheel and the tub bottom.
  • the present invention has precisely for its purpose to remove this drawback by using a roller bearing device interposed between the agitating wheel and the tub bottom so as to prevent friction between these two elements.
  • Such a device remains very simple, can be manufactured at a low cost and additionally improves the good operating characteristics of the machine.
  • the roller-carrying ring is a flat member whose outer periphery is provided with supporting lugs on which the said rollers are mounted.
  • the latter may for instance be made through moulding from a suitable plastics and have a slightly conical rolling surface.
  • a line agitating turbine-wheel 2 provided with ribs 3 is adapted to be moved slowly in rotation through the medium of a shaft (not shown) driving a pinion 4 meshing with teeth 5 provided at the periphery of the agitating wheel 2.
  • the shaft driving the pinion 4 is located in a compartment formed by the wall 6 of the machine tub and a wall 7 provided within the tub.
  • a device for progressively driving the pinion 4 and, therefore, the agitating wheel 2 may be provided. Such a device is not illustrated since it is not within the scope of the present invention.
  • a ring 10 provided at its periphery with a plurality of rollers or the like 1 I is interposed between the agitating wheel 2 and the bottom of the tub I.
  • the agitating wheel 2 comprises a rotary shaft 16 (FIG. 1) penetrating into the rolling plate, so that the plate 13, the ring 10 with its rollers 11 and the agitating wheel 2 can be assembled to one another by means of a clip or the like 17 mounted in proximity to the end of the shaft 16 of the agitating wheel 2, the latter together with the plate 13 advantageously forming a rolling cage.
  • a washing machine in particular a linen washing machine, comprising a tub, a wheel constituting a large-diameter turbine and extending over the greater part of the tub bottom, gear means for slowly driving the said wheel in rotation, and plate means removably fastened at the bottom of the tub and on which the said wheel is pivotally mounted
  • the improvements consisting in that the said machine further includes rolling means interposed between the said wheel and the said plate as well as circular guiding means provided in the wheel and the plate, and engaging the said rolling means during the rotation of the wheel in the tub.
  • washing machine according to claim 1, wherein the said wheel is provided with a shaft penetrating into the plate means and retained in the latter by a clip.
