Definitions

  • the present invention relates to a laundry basket with axes or incorporated shafts, and a washing machine provided with such a basket.
  • washing machines with horizontal basket usually comprise a line basket rotatably mounted around the axes or aligned horizontal shafts rotating in bearings fixed on opposite flanges of their tank. Being in contact with a more or less corrosive washing liquid, these shafts or shafts are frequently made of a material insensitive to corrosion, such as metals or stainless metal alloys which are usually relatively expensive.
  • these axes or shafts have bases fixed to the opposite end walls of the basket, by means of counter-cups and fixing rivets, staples or screws.
  • FR-A 2 493 885 a washing machine with drum is described rotating in a tank around two axially aligned removable shafts.
  • This laundry drum is in fact provided, at each of its two flanges and concentrically with its axis of rotation, with an aluminum base permanently fixed by crimping, receiving one end of a removable aluminum shaft, the other of which end is integral with a bearing mounted on the tank, this removable shaft being blocked on this base by an axial screw which crosses its entire length.
  • Such a structure is long and expensive to manufacture and assemble.
  • the aim of the present invention is to avoid these drawbacks and makes it possible to produce a laundry basket made of economical sheet metal with incorporated aligned axes or horizontal shafts, securely held in position on the end walls of the basket and resistant to corrosive washing liquid, all by presenting a simple structure easy to manufacture and comprising a relatively small number of component parts compared to a sheet metal laundry basket of known type with axes or shafts fixed by rivets, screws or staples.
  • the invention also relates to a washing machine provided with such a laundry basket.
  • a laundry basket with aligned axes or shafts, supported by bearings in a tank of a washing machine comprises in each of its sheet metal end walls, a tubular shaft of mechanically resistant metal, - an opening formed concentrically with the axis of rotation of the basket and intended to receive an end fixed permanently by crimping, of this tubular shaft, - bordered holes being formed spaced apart and regularly distributed around this opening, - a base overmolded in a synthetic material resistant to the temperature and corrosion of the washing liquid.
  • a washing machine 1 produced according to the invention and partially illustrated in FIGS. 1 to 3, comprises in a tank 2, a horizontal basket of sheet metal laundry 3 rotatably mounted around its two aligned horizontal axes or shafts, schematically represented in 4 and 5.
  • These shafts 4 and 5 of the basket 3 are carried according to a known technique by bearings of known types not shown respectively fixed in a known manner on the two corresponding flanges 6 and 7 of the tank 2, one 4, of these shafts projecting towards the outside of the tank 2.
  • a pulley 8 which, under the drive of a motor 9, communicates a rotational movement to the laundry basket 3.
  • the shafts 4 and 5 are made of metal tubes sensitive to the corrosive action of the washing liquid, inexpensive, capable of being shaped by shrinking and having good mechanical strength.
  • the axes or tubular shafts 4 and 5 are incorporated into the sheet metal laundry basket 3 and form an integral part of the opposite end walls made of sheet metal of the latter, in other words these shafts cannot be separated from these walls by sheet of this basket without causing damage to this assembly, unlike riveted, screwed or stapled shafts or shafts which can be removed by diverting, unscrewing or stapling.
  • the horizontal sheet metal basket 3 for this purpose comprises, in each of its end sheet walls 19 and 20, a tubular shaft 4 or of mechanically resistant metal, - an opening 10 formed concentrically with the axis of rotation of the basket 3 and intended to receive one end of this tubular shaft 4 or 5, which is fixed there permanently by crimping, - protruding rim holes 11 hereinafter bordered holes 11, formed spaced apart and regularly distributed around this opening 10 , and a base 12 molded in a synthetic material resistant to the temperature and corrosion of the washing liquid.
  • tubular shaft 4 or 5 is crimped onto a metal base, itself crimped onto the corresponding end wall 19 or 20 of the basket 3 at the level of the bordered holes 11 and by the projecting edges of these.
  • the base 12 performs three functions, that of assembly, that of protecting the parts of the tubular shaft 4, 5 exposed to the corrosive washing liquid and that of sealing.
  • the base 12 molded onto the inner face and the outer face of the sheet metal end wall zone of this basket 3 surrounding the opening 10, and through towards bordered holes 11, - on a section 13 of the outer surface of the end of the shaft crimped at the edge of this opening 10, - and on the crimped end and the wall of the bore of this shaft, this which reinforces the rigidity of the assembly and protects the part of the shaft normally in contact with the corrosive washing liquid.
  • the base 12 which closes the crimped end of the tubular shaft at 14 contributes to ensuring a seal of the washing machine at this shaft in cooperation with a known system of rotary seal not shown, mounted in a manner known on the section 13 of the shaft protected by the base 12. By filling the bordered holes 11 and covering the section 13 of the shaft adjacent to the laundry basket 3, the base 12 strengthens its anchoring in this basket 3 and ensures good cohesion of the assembly of the shaft to this basket.
  • the base 12 further comprises stiffening ribs distributed on its outer face, namely in the illustrated example of the radial ribs 15, 16 angularly spaced and a circular rib 17 concentric with the shaft which contribute to securely hold this shaft in position.
  • a sheet metal laundry basket 3 which is thus produced with incorporated shafts 4 and 5 proves to be economical and easy to manufacture and assemble, while ensuring great structural solidity, good mechanical resistance to operation and excellent resistance to liquid. corrosive to washing and helping to lower the cost price of the washing machine.
