Definitions

  • the present invention relates to a spider specifically designed for washing machine baskets with high speed centrifugation operation.
  • the invention relates moreover to a washing machine basket including the inventive spider, as well as a method for making the basket.
  • the present invention relates to a method for making washing machine baskets, i.e. cylindric or drum vessels, in which are held cloth articles to be washed and dried.
  • the drying operation requires to operate the basket with a very high spinning rate or speed, thereby quickly and efficiently drying the washed articles.
  • Prior washing machine baskets conventionally made with the spider spokes coupled by rivets to the basket bottom, directly at their end portions, do not allow to exceed a rate limit of 1,000-1,200 RPM's.
  • the basket construction mainly if fully loaded, tends to be deformed, i.e. to deform the more stressed surfaces thereof.
  • the aim of the present invention is to provide a novel washing machine spider and basket, adapted to efficiently operate at spinning rates of the order of 1,000, 1,200, 1,400, 1,600 RPM's and more.
  • a main object of the present invention is to provide such a washing machine basket adapted to efficiently resist up to a spinning speed or rate of 1,600 RPM's, while having a construction much more simple and unexpensive than that of prior washing machine baskets.
  • Another object of the present invention is to provide an efficient method for making the inventive basket.
  • the inventive basket provides the advantage that it can resist against stresses generated at rate values of 1,000, 1,200, 1,400, 1,600 RPM's and more, while having a much more simple and unexpensive construction.
  • the washing machine basket according to the present invention has been generally indicated in Figure 1 by the reference number 1.
  • Said basket comprises a substantially drum-like body, including a stainless steel perforated sheet mantle 2, provided, on a side thereof, with a bottom 3 and, on the opposite side thereof, with an inlet 4 ( Figures 5 to 9).
  • a spider 5 On the side of the basket 1 closed by the bottom 3 a spider 5, clearly shown in Figure 2, is arranged.
  • Said spider made as a single-piece, comprises a ring element 6, coupled to a central hub 7 by a plurality of radially extending arms or spokes 8 (six spokes being shown in the considered embodiment).
  • a shaft 9 is provided at said hub 7, so as to connect said spider 5 and, accordingly, the basket 1, to a motor-reducing unit of the washing machine (not specifically shown).
  • the ring element 6 is provided, on a side thereof facing the basket bottom 3, with a plurality of projections or lugs 10, provided for engaging in corresponding elongated slots 11 of the bottom 3 (see Figure 4).
  • peripheral edges 12 of the mantle 2 and 13 of the bottom 3 are at the start overlapped in a raised position thereof, thereby providing at least a portion thereof transversely arranged with respect to said bottom 3. Owing to the disclosed arrangement, the peripheral edges will provide self centering means for self centering the ring element 6 of the spider 5 with respect to the axis 18 of the basket ( Figure 1).
  • connection of the ring element 6 to the bottom 3 and, accordingly, of the spider 5 to the basket 1, is made by clamping, by deforming the edges 12 and 13, at first by bending said edges under a recess 15 provided on the outer edge of the ring element 6 ( Figure 7) and then by forming a curled portion 16 of the overlapping edges 12 and 13 ( Figure 8) and, finally, by pressing the curled portion on itself and inside said recess 15, thereby providing a firm connection (Figure 9).
  • the inlet 4 is connected to the mantle 2 of the basket 1.
  • connection of the ring 6 at the elongated slots 11 of the bottom 3 is carried out at the level of the projections 10 of said ring element 6 ( Figures 6, 10 and 11).
  • Such a clamping operation is made by up-turning the edge 20 of the elongated slots 11 about the corresponding end portion 21 of said driving elements 19, which portion has a substantially L-shape configuration.
  • the driving or entrainment elements can be of any suitable desired type, as commercially available, or they can be provided at separate fittings, i.e. detached from the basket (for example of any suitable plastic materials) or they can be made as a single-piece on said basket.
