Definitions

  • the present invention relates to a method for assembling and making a basin assembly for washing machines, and also relates to the basin assembly made thereby.
  • washing machines usually comprise a basin assembly for holding washing water and supporting the rotary basket, which is substantially made by coupling its component elements by using screws or bolts.
  • the document GB 2096649 discloses a method for making and assembling a basin for washing machines in which the tubular element forming the basin body is closed at the front by a front wall which is perimetrically clamped with the corresponding axial end of the tubular element and at the rear by a rear wall, a sealing gasket being arranged between the tubular element and front wall near the clamping zone; the tubular element further comprises a rear flange and a front flange therethrough there is defined the linen loading opening of the washing machine, the bottom flange being affixed to the rear wall and front flange being affixed by longitudinal tie plates to the front wall.
  • the aim of the present invention is to overcome the above mentioned drawbacks, by providing a basin assembly, for washing machines, which comprises a very reduced number of multi-functional component elements.
  • a main object of the present invention is to provide such a basin assembly for washing machines, which can be easily and quickly assembled.
  • Another object of the present invention is to provide such a basin assembling method which affords the possibility of mutually coupling the several basin component elements without using bolts or screws.
  • the method for assembling a basin assembly or unit, for washing machines provides that the tubular element 1 and rear wall 2 jointly forming, together with an annular element or front flange 3, the basin for the washing water, which basin has been generally indicated at the reference number 4, are mutually coupled by seaming, at 5, their corresponding perimetrical portions.
  • the above mentioned rear wall is moreover provided, as shown, with a perimetrical recess, in which is engaged a peripheral portion 7, of like shape, of a rear flange 8 including bearing members for supporting the shaft of a rotary basket 9.
  • the rear flange is perimetrically fixed by a pair of coupling elements, that is a top coupling element 10 and a bottom coupling element 11 which encompass the corresponding end portions of said flange.
  • the rear flange 8 is coupled to said coupling elements 10 and 11 by means of a plurality of rivets 15 which are applied at an end portion of said flange (figure 2) or at corresponding end portions of said coupling elements (figure 3) which, in this case, are suitably extended on the flat surface of said flange.
  • the disclosed coupling elements are so designed and arranged as to support corresponding weight members 16 which operate to properly balance and weigh the basin assembly.
  • weight members preferably consist of a sheet metal plate embedded in a concrete block and are provided with suitable projecting perimetrical lugs for anchoring the plate to the corresponding coupling elements.
  • the top coupling element 10 is so designed as to lock bearing spring members 17 and, as it is used in drying-washing machines, it will be also provided with an attachment or fitting for the heating and fan assembly (without the need of using bracket members).
  • the bottom coupling element 11 is so designed and arranged as to support, without the use of bracket members, the electrical motor 18, the bottom balancing weight 16 and the plates of the dampers.
  • the disclosed coupling elements operate to structurally bind the rear flange, basin and front flange by means of the closure ring member 14 thereby providing an integral and very rigid and strong unit.
