Definitions

  • the invention relates to a laundry washing machine equipped with a conventional laundering tub mounted in the housing of the machine in a novel manner.
  • Conventional laundry washing machines for domestic use are equipped with a metal laundering tub provided with suitable ballast weights and adapted to contain a rotatable drum.
  • the tub is mounted in the housing of the machine by upper suspension springs and lower vibration dampeners adapted to engage suitable metal brackets secured to the outer periphery of the tub and to the interior of the housing, respectively.
  • the conventional laundering tub is additionally provided with further brackets or lugs secured to its outer periphery for mounting a motor assembly required for rotating the drum, and a pressure-sensing outlet for the connection thereto of a pressure switch.
  • a laundry washing machine comprising a laundering tub adapted to contain a drum mounted therein for rotation by means of at least one electric motor of conventional type supported by associated lugs, said tub being mounted in the housing of the machine by means of suspension elements from above and vibration dampener elements of conventional type from below, said elements being adapted to be engaged with associated brackets, said machine being additionally provided with a pressure-sensing dome for the connection thereto of a pressure switch of conventional type, and being characterized by comprising at least one circular hoop of a plastic material adapted tc be removably secured to the outer periphery of the tub in intimate engagement therewith, said hoop being integrally provided with said lugs, said brackets and said bressure-sensing dome, and being additionally formed with two backwards folded end portions adapted to be connected to one another by resilient means.
  • a domestic laundry washing machine 3 of the front- loading type provided with a metal laundering tub 4 adapted to contain a rotatable drum 5 and mounted within the housing 7 of the machine by means of upper suspension springs 8 and lower vibration dampeners 9 or similar elements of conventional type.
  • tub 4 is accomplished by means of a circular hoop 10 made of a plastic material and being of a smaller width than said tub, said hoop 10 being adapted to be removably secured to tub 4 in intimate engagement with the outer periphery thereof.
  • Hoop 10 is formed with two backwarts bent end portions 11 and 12 adapted to be connected to one another by at least one tension spring 13 or the like for clamping hoop 10 in position on tub 4.
  • Integrally formed with hoop 10 are two pairs of brackets 14 and 15, two parallel lugs 16 and 17, and at least one pressure-sensing dome 18 for the connection thereto of a conventional pressure switch (not shown).
  • the pair of brackets 14 is adapted to be engaged by respective ends of suspension springs 8, the other ends of which are engaged with respective metal brackets 19 secured to upper portions of housing 7 of the machine.
  • the pair of brackets 15 on its part is adapted to have respective ends of vibration dampeners 9 hinged thereto, the other ends of vibration dampeners 9 being hinged to respective bearing brackets 20 secured to lower portions of housing 7.
  • Lugs 16 and 17 finally serve for supporting a conventional electric motor 21 required for rotating drum 5 by means of a belt transmission 22 in a per se known manner.
  • hoop 10 functioning as the carrying structure for the tub and drum assembly and for motor 21 and including pressure-sensing dome 18, it is thus possible to make the tub itself with a reduced wall thickness, resulting in a saving of material for its manufacture.
  • the hoop is a separately foremd unit adapted to be applied to the tub by an automatized process by means of a robot or a similar machine.
