Definitions

  • the present invention relates to a device for supplying a washing agent in a washing machine, particularly a machine for washing laundry, of the kind defined in the preamble of claim 1.
  • GB-A-2 187 763 discloses a device of this kind wherein the limitation wall includes an upper stationary portion and a lower movable portion rotatably hinged to the stationary portion about an essentially horizontal axis.
  • the limitation wall includes an upper stationary portion and a lower movable portion rotatably hinged to the stationary portion about an essentially horizontal axis.
  • DE 19617471 A1 discloses a syringe-like dispensing device adapted to supply either a viscous or a liquid washing agent to the washing tub of a washing machine.
  • the dispensing device may be operated manually or automatically by the washing program control.
  • An object of the present invention is to provide an improved supply device of the type specified initially, which can be used equally well with washing agents of the solid or powder type, or of the liquid type.
  • the letters WM indicate the whole of a washing machine.
  • This machine comprises, in a known way, a supporting housing 1, of generally parallelepipedal shape.
  • the machine WM is of the front loading type, and thus has a front door 2 for access to the washing chamber.
  • the washing machine WM comprises a device 10 for supplying washing agents, such as detergents and the like.
  • this device 10 comprises an essentially box-like container 11, fitted in the machine WM in such a way that it is movable between a retracted closed condition ( Figures 3 and 4 ) and an (at least partially) extended open condition ( Figures 1 and 2 ).
  • the container 11 forms at least one receptacle 12 which is open at the top.
  • the receptacle 12 is delimited frontally by a frontal wall 13 of the box-like container 11, and laterally by a pair of longitudinal walls 14 and 15, which are essentially vertical and parallel to each other.
  • the receptacle 12 is delimited below by a bottom wall indicated by 16 in Figure 2 and the subsequent figures.
  • the receptacle 12 is delimited at its rear by a wall 17 fitted so that it can swing, like a "butterfly" valve, about an essentially horizontal axis A located at a predetermined height above the bottom wall 16.
  • the delimiting wall 17 has a breadth equal to the transverse distance between the lateral walls 14 and 15 of the receptacle 12, and in an intermediate area of its vertical walls it has corresponding pins with horizontal axes 17a and 17b, aligned with each other and engaged rotatably in corresponding apertures provided in the lateral walls 14 and 15 of the receptacle 12.
  • the delimiting wall 17 can swing between a position of containment, shown in Figures 2 and 3 , in which it extends essentially in a vertical plane, against a stop 18 integral with the box-like container 11, and an inclined discharge position ( Figure 4 ) in which it extends in a plane inclined downwards and towards the interior of the machine, so that its lower edge or margin is spaced vertically apart from the bottom wall 16 of the container 11.
  • a spring 19 is associated with the delimiting wall 17, and tends to push this wall into the containment position, against the stop element 18.
  • this spring is a torsion spring, with an upper arm 19a which bears on a stop 20 integral with the box-like container 11, and a lower arm 19b which bears on a stop 21 integral with the wall 17.
  • the upper portion of the delimiting wall 17 has a formation 22, creating a centring recess 23, on its face which is turned towards the interior of the machine WM.
  • the delimiting wall 17 is associated with a controlled actuator device, illustrated only partially in these figures, in which it is indicated as a whole by 24.
  • this actuator device comprises a rod-shaped pushing member 25 which is translatable essentially in its axial direction.
  • the end of this pushing member 25 which points towards the box-like container 11 can engage in the centring recess 23 of the delimiting wall 17.
  • the actuator device 24 is made in such a way that the pushing member 25 can assume a retracted rest position ( Figure 3 ) in which it allows the delimiting wall 17 to place itself and remain in the containment position, under the action of the spring 19, and an advanced operating position ( Figure 4 ) in which it places the delimiting wall 17 in the discharge position, against the action of the return spring 19.
  • the pushing member 25 can be moved from the rest position to the operating position in one of various known ways, for example by means of a solenoid, an electric motor, or other means.
  • the movement of this pushing member can be controlled directly by a movable member of a hydraulic distributor device (of a known type) designed to supply a flow of water to the receptacle 12 of the box-like container 11, to wash out and thus evacuate the washing agent contained therein.
  • the user intending to carry out a washing cycle pulls out the box-like container 11, placing it for example in the position shown in Figures 1 and 2 .
  • the delimiting wall 17, which is carried by the box-like container 11, is disengaged from the actuator device 24, and particularly from the pushing member 25.
  • This wall 17, which can conveniently be provided with a seal around its periphery if necessary, delimits the rear of the receptacle 12 formed in the box-like container 11.
  • the user can then pour a quantity of a washing agent, which can be solid or in powder form or liquid, into the receptacle 12. If the washing agent is liquid, the wall 17 prevents the liquid washing agent from flowing into the washing machine WM.
  • a device for controlling the operation of the machine activates the actuator device 24, whose pushing rod 25 moves to the advanced operating position shown in Figure 4 , causing the delimiting wall 17 to swing towards its discharge position.
  • the washing agent previously loaded into the receptacle 12 can be supplied to the washing chamber of the machine.
  • this washing agent is of the liquid type, it can be supplied by the natural downward flow of the agent and/or as a result of its washing out by a flow of water supplied to the receptacle.
  • washing agent is of the solid or powder type
  • this agent is transferred to the washing chamber by being washed out by a flow of water supplied in a known way to the receptacle 12 by means of a suitable hydraulic distribution device.
  • the supply device makes it possible to use a washing agent of the liquid, solid, or powder type without affecting the process.
  • the movable delimiting wall 17 of the receptacle 12 is not fitted on the box-like container 11, but can be brought into a fixed position by the structure 1 of the washing machine WM in such a way that it extends into the box-like container 11, which, as in the example of embodiment described above, can slide with respect to the said wall in its movement between the retracted closed condition and its at least partially extended open condition.
