Definitions

  • the present invention relates to an improvement in the basket of washing machines. More particularly, this invention relates to a basket of the type mentioned above, which provides a system for reuse of water present on the bottom of the tub so as to obtain, by employing lowered amounts of water, a remarkable reduction both in electric power and in detergent consumption.
  • washing machines which are programmed so as to work through washing cycles that can be adapted to various conditions, more particularly as functions of the fabric to be washed and of the dirt degree, in an attempt at limiting as much as possible the consumption of electrical power.
  • Some programs are prepared for example to allow strong and not too dirty fabrics to be washed. Such programs provide the employment of not too high washing temperatures (lower than 60°C) in order to save electrical power, as mentioned above.
  • programs are prepared that make use of lower amounts of water, more particularly in the case of loads which are not complete, so that power is saved.
  • a further solution provides the employment of a water amount which is just sufficient to soak the fabrics so that, as a counterpart of the saving in electrical power and detergent, a wear of said fabrics occurs which is much higher than the wear occurring when washing operations are carried out employing higher amounts of water.
  • a basket for washing machines comprising dragging members provided on the perimeter of the inside surface of said basket and being characterized in that mechanical means are provided at points corresponding to each one of said dragging members, outside the surface of the basket, said means being designed for collecting water from the washing machine tub and for containing said water inside the space formed by said dragging member and by the mechanical means themselves, said basket being also characterized in that each one of said dragging members is provided in its inside part with at least one series of holes for allowing the collected water to fall.
  • said mechanical means are made up of a dam provided outside said dragging member, said dam being realized so as to leave an inlet port for water in said space, said port being arranged in a forward position with respect to the sense of rotation of the washing machine basket.
  • said dragging members can be so shaped as to obtain at least one step on the bottom surface of said dragging member in order to increase the volume of water carried by the same.
  • said mechanical means can also consist of extension of the outside surface of the basket itself, a number of apertures being provided on the transverse lateral outside surfaces of said dragging members, said apertures being designed for the collection of water itself.
  • each dragging member can be changed in order to increase the collecting and containing possibility of the same.
  • the washing machine 1 comprises a tub 2 in which the rotating basket 3 is provided, said basket bearing holes on its surface 4.
  • Said rotating basket 3 is provided with the dragging members 5 which are of aid in making the motion of the fabrics to be washed contained inside the same easier.
  • the rotation motion of the basket 3 is obtained by means of an electric motor 6 and through the belts 7 and pulleys 8.
  • the solution suggested according to the present invention can be provided on any type of the washing machines commercially available, the basic operation of the washing machine being kept unchanged.
  • a dam 9 (see Figure 2) is provided outside the rotating basket 3 at points corresponding to each one of the dragging members 5, said dam defining the space 10 formed just as a consequence of the realization of said dragging members 5.
  • Said dam 9 is so realized as to provide an opening 11 in a forward position with respect to said space 10 and to the rotation sense of the basket 3 (according to arrow 12 in Figure 2).
  • Holes 13 are provided longitudinally on said dragging members 5 below said space 10.
  • Figure 4 shows an embodiment of the basket 3 according to the present invention wherein, by modifying the shape of said dragging member 5 so as to form the step 15, an increase is obtained in the volume of the space 10 and consequently an increase is obtained in the volume of water dragged by each single dragging member 5 as well as an increase in the angle at which the falling of water occurs.
  • the embodiment shown in Figure 5 is particularly suitable to obtain the effect disclosed above with washing machines in which the rotation of the basket 3 is provided in both senses.
  • the space 10 is completely closed at the top by the extension of the surface 4 of the rotating basket 3. Obviously, the surface 4 will bear no holes at points corresponding to the closure of the space 10.
  • openings 16 will be provided on the lateral surfaces of the dragging member 5 (one only opening is shown in the Figure) which openings allow water to be introduced inside the space 10 independently of the sense of rotation of the rotating basket 3.
