Definitions

  • a machine having a unidirectional or reciprocating rotary motion such as a washing machine, wherein a container is provided which can be charged with a ballast material, preferably water, in order to dampen the oscillations and vibrations transmitted to the whole machine during its operation, the ballast material being dischargeable to facilitate the transport and the handling of the machine.
  • a ballast material preferably water
  • the object of this invention is that of obviating the drawbacks mentioned above by providing a means able to limit the oscillations and vibrations of the machines-or of their members during their operation by increasing their weight, the said weight being easilyeliminated for any eventuality.
  • the advantages ofleied by the invention derive principally from the fact that the container or containers can be filled (and naturally emptied) with ballast material, water for preference because it is more easily obtainable, more easily introduced and more easily discharged than other ballast materials.
  • the container or containers are filled with such a ballast material so that the oscillations of the tank are liinited in the case of washing machines with oscillating tanks, or of the entire machine in the case of washing machines with fixed tanks.
  • FIG. 1 is a diagrammatic sectional view of a washing machine with a fixed tank furnished with two containers according to the invention
  • FIG. 2 is a diagrammatic sectional view of a washing machine with a fixed tank furnished with one container according to the invention
  • FIG. 3 is a sectional diagrammatic view through the line Ill-Ill of FIG. 4 of a washing machine having a fixed tank furnished with two other types of container;
  • FIG. 4 is a diagrammatic sectional view through the line IV-IV of FIG. 3;
  • FIG. 5 is' a diagrammatic sectional view of a vwashing machine with an oscillating tank furnished with one tank according to the invention
  • FIG. 6 is a diagrammatic sectional view of a washing machine with an oscillating tank furnished with two containers according to the invention
  • FIG. 7 is a diagrammatic view in elevation of a washing machine with an oscillating tank furnished with another type of container according to the invention.
  • FIG. 8 is a diagrammatic sectional view through the line VIII-VIII of FIG. 7;
  • FIG. 9 is a sectional diagrammatic view through the line X-X of FIG. 10 of a washing machine with an oscillating tank furnished with two elastically deformable containers;
  • FIG. 10 is a plan view of FIG. 9;
  • FIGS. 11-12 are two variations of FIGS. 9-10.
  • FIG. 1 shows a washing machine 10 whose tank 11 is rigidly fixed to the housing of the machine.
  • a pulley 12 is keyed on to the shaft of the basket 13 which receives its motion from the motor 14 by means of a belt drive 15.
  • FIG. 2 shows a washing machine 20 with a fixed tank as in FIG. 1 where a container 21 shaped so that it hugs the lower part of the tank 11 is arranged between the bottom surface of the housing and tank itself.
  • FIGS. 3 and 4 show a washing machine 10 with a fixed tank as in FIGS. 1 and 2 but provided with two containers 22 arranged between the tank 11 and the two opposite lateral walls of the washing machine, and shaped so as to hug the lower and lateral parts of the tank 11.
  • FIG. 5 shows a washing machine 10 whose oscillating tank 11 is suspended from the housing by means of upper springs 23 and shock absorbers 24.
  • FIGS. 6-7-8 are other examples of fixing one or more containers rigidly to the oscillating tank of the machines which however do not change the'concept of the invention and are not intended to represent any limitation on it.
  • FIGS. 9-10-11-12 illustrate a washing machine 10 also with two elastically deformable containers 26 fixed rigidly to the oscillating tank 11 and placed between the tank itself and the opposite walls of the housing. By introducing ballast material into the containers 26, a certain weight acts on the tank so limiting oscillations.
  • the containers are of a material such that, on the introduction of ballast material,(preferably water), they do not deform or at least they deform very little. However on the introduction of light and expansible fluid such as air at high pressure, the containers deform and are pushed against the opposite lateral walls of the housing, if necessary with the interpositioning of distance piecesor spacers 30 (FIGS. 11-12). In this situation any movementof the tank is impeded.
  • ballast material preferably water
  • the container can be provided with heating means for using the ballast water as hot water for the washing processes.
  • the container is connected to the feed pipe and to the wash tank.
  • a washing machine comprising a housing, a wash tank mounted within said housing for oscillatory movement, and container means for selectively dampening oscillations and vibrations of said washing machine during the normal operation thereof and retarding movement of said tank relative to said housing during transport.
  • said container means has means for selectively filling the same with and removing therefrom a ballast material for effecting said dampening of oscillations and vibrations and a lightweight medium under pressure for efiecting said tank retarding movement.
  • said container means is in the form of a deformable container fixed relative to said housing and normally closely spaced from said tank, said container when filled with ballast material being spaced from said tank and when filled with a medium under pressure being in contact with said tank.
  • ballast material is water
  • a washing machine as claimed in claim 2 in which means are provided for heating water stored as ballast material in said container so as to be utilizable in wash processes of said washing machine, said wash tank having coupled thereto a water feedpipe, and said container being in communication with said water feedpipe and said wash tank for supplying wash water from said container to said wash tank.
  • a washing machine comprising a housing, a wash tank mounted within said housing for oscillatory movement, and container means for storing water as ballast for dampening oscillations and vibrations of said washing machine during the normal operation thereof, and means for heating water stored as ballast material in said container so as to be utilizable in wash processes of said washing machine, said wash tank having coupled thereto a water feedpipe, and said container being in communication with said water feedpipe and said wash tank for supplying wash water from said container to said wash tank.
