Definitions

  • This invention relates to a combined machine for washing laundry and subsequently drying it by continuously circulating heated air therethrough.
  • Machines of this type are conventionally provided with a washing assembly and in addition with at least one fan and associated heater elements for generating a stream of hot air flowing within the drum of the washing assembly and the laundry contained therein.
  • the washing assembly itself is provided with at least one dampening mass for its equilibration during rotation of the drum, particularly during the centrifuging phases.
  • the assembly formed by the fan and the heater elements is enclosed in a separate housing mounted within the frame of the machine and provided with suitable heat-insulation for ensuring efficient heating of the air employed for drying.
  • a combined washing and drying machine comprising a tub, a drum mounted for rotation within said tub and adapted to contain the laundry to be washed and dried, a dampening mass for equilibrating the oscillating system formed of said tub and drum, a fan, and heater elements for generating a flow of heated air and for circulating the heated air through said laundry.
  • a machine of the above specified type is characterized in that said dampening mass consists of a plate of a material having a high specific weight and designed to form a seat for mounting said fan, and provided with an opening for receiving a first duct communicating with said tub, the plate also comprising a heat-insulated chamber for containing said heater elements, said chamber communicating with the outlet of said fan on the one side, and with a second duct connected to said tub on the other.
  • a combined washing and drying machine shown in Fig. 1 generally comprises a frame 3, a wash tub 4 resiliently mounted within said frame in a per se known manner, a drum 5 adapted to contain the laundry disposed within the tub and adapted to be rotated by a (not shown) motor, and conventional functional components (not shown) for controlling the operation cycles of the machine.
  • the machine shown in the drawings is in addition provided with a dampening mass in the form of a plate 6 formed of a material having a high specific weight, preferably cast iron, and mounted fixedly on said tub 4 for equilibrating the assembly formed of the tub and the drum.
  • a dampening mass in the form of a plate 6 formed of a material having a high specific weight, preferably cast iron, and mounted fixedly on said tub 4 for equilibrating the assembly formed of the tub and the drum.
  • plate 6 is designed to carry at least one fan 7 and associated electric heater elements 8 for generating a flow of heated air to be supplied to drum 5 via a conduit 9 connected to plate 6 for drying the laundry contained in drum 5.
  • plate 6 is formed with a bottom wall 10 surrounded by a peripheral wall 11.
  • Bottom wall 10 itself includes two planar portions 12 and 13 connected to one another in parallel relationship and formed each with a through-opening 14 and 15, respectively.
  • Fan 7 is mounted in a per se known manner on planar portion 12, so that its inlet 16 is aligned with opening 14, while its outlet 17 is directed towards planar portion 13.
  • a panel 18 Disposed on planar portion 13 is a panel 18 formed of a thermally insulating material so as to cover the entire surface of planar portion 13 as well as the interior surface of the peripheral wall portion 11 surrounding it. Panel 18 is further formed with a through-opening 19 aligned with opening 15.
  • Heater elements 8 are disposed above planar portion 13 with their terminals 20 and 21 extending through peripheral wall 11 for connection to electric leads (not shown). Heater elements 8 are retained in position by suitable spacers 22 and 23 disposed between heater elements 8 and panel 18 on the one hand and a further panel 24 formed of a heat-insulating material and removably attached to plate 6, so that heater elements 8 are retained at a suitable distance from both panels 18 and 24.
  • the provision of the heat-insulating panels permits efficient heating of the air flow generated by the fan and prevents the generated heat to be transmitted to other functional components of the machine located adjacent plate 6.
  • the heater elements 8 are enclosed in a protective sheath 26 of stainless steel or another suitable material, to prevent incandescent scales possibly set free by the heater elements from being carried into the drum and from damaging the laundry therein.
  • the plate forming the dampening mass thus provides seats for the fan and for the heater elements, eliminating the necessity of the formerly employed separate housing for this purpose.
  • the construction of the washing and drying machine is accordingly simplified, so that the mounting of the remaining functional components of the machine can be carried out in a simple and economical manner.
  • the fan and the heater elements are readily accessible in case of damage or malfunction and for normal maintenance work. It is of course possible to mount the fan and heater elements on the dampening plate, or the dampening plate itself with respect to the tub, in a different manner without leaving the scope of the present invention.
