  • power supply means including an electric circuit (not shown in the drawings) connected to the first end 31A and/or to the second end 31B of the shape memory element 31.
  • the activation of the actuator through an electric circuit always causes the actuator to move from a first original condition to a second operating condition; when no longer activated, the actuator always returns into the first original condition.
  • the actuating element 31 can be in a first operating condition (shown in Figs. 3a , 5a and 7a ), wherein it is not activated and has a certain first length L1; upon activation of the electric circuit connected to the first end 31A and/or to the second end 31B, the actuating element 31 can switch to a second operating condition (shown in Figs. 4a and 6a ), wherein it is activated and has a certain second length L2, shorter than said first length L1.
  • said first length L1 and second length L2 are represented by a dash-dot-dot line.
  • the shape memory actuating element 31 according to the present invention can become shorter following the activation of the electric circuit connected to the first end 31A and/or to the second end 31B.
  • said first end 31A and second end 31B of the actuating element 31 are positioned on substantially opposite sides relative to said pin P.
  • the first end 31A of the actuating element 31 is associated with the dispensing device 10; it is however clear that the first end 31A of the actuating element 31 may also be directly associated with the washing machine 1.
  • the arm 13 and the movable member 30 are associated with each other through the pin P, which is common to both such components; it is however clear that the arm 13 and the movable member 30 may alternatively be associated with each other in a different manner.
  • the movable member 30 comprises a branch 30D, the movable member 30 and said branch 30D being so designed as to form a substantially L-shaped body.
  • Said branch 30D of the movable member 30 is adapted to abut on said release means 21, in particular on the rod 21 associated with a small pump, in order to dispense the rinse aid agent contained in the container 20.
  • said elastic means comprise a tongue 40 with a first portion 41A secured to the dispensing device 10 and a second portion 41B adapted to abut on the movable member 30, in particular on said branch 30D of the movable member 30.

  • said rod 21 comprises:
  • the actuating element 31 When the actuating element 31 is activated, it moves the movable member 30 in a first rotation direction S1 (see Fig. 4a ) and causes the activation of the locking mechanism or arm 13; as a result, the rotation of the movable member 30 in said first rotation direction S1 allows the tooth 13D of the arm 13 to be disengaged from the serration 12D of the lid 12 (see Fig. 4b ), thus opening the lid 12 (visible in Fig. 5b ).
  • the movable member 30 undergoes the thrust exerted by the elastic means 40 and rotates in a second direction S2, thus overcoming the so-called "dead centre” and getting in a situation wherein said first end 31A and second end 31B of the actuating element 31 are aligned above the pin P (see Fig. 5a ).
  • the activation of the actuating element 31 causes further movement of the movable member 30 in a second rotation direction S2, which in turn moves and activates said release means 21 to release the rinse aid agent contained in the container 20.
  • the repeated activation of the actuating element 31 allows to obtain successive actuations of said release means 21, in particular of the small pump associated with the rod 21, by the branch 30D of the movable member 30; said successive actuations allow to obtain a measured and metered release of the rinse aid agent contained in the container 20, said release being correlated to the number of activations of the actuating element 31.
  • the user can close the lid 12 again in order to bring the dispensing device 10 back into the initial condition shown in Fig. 3a , i.e. with the tooth 13D of the arm 13 engaged with the serration 12D of the lid 12, and with the movable member 20 (associated with the arm 13 through the pin P) in an operating condition wherein said first end 31A and second end 31B of the actuating element 31 are aligned under the pin P.
  • the dispensing device 10 is shown in Figs. 7a and 7b in a condition that precedes the closing of the lid 12 by the user; in fact, the serration 12D of the lid 12 is near the tooth 13D of the arm 13.
  • said dispensing device 10 comprising:
  • said method of operation comprises the steps of:
  • said actuating element 31 consists of a single shape memory element and said steps a) and c) of activating the actuating element 31 are carried out by activating power supply means comprising an electric circuit (not shown in the drawings) connected to the first end 31A and/or to the second end 31B of the actuating element 31 or single shape memory element.
  • activating power supply means comprising an electric circuit (not shown in the drawings) connected to the first end 31A and/or to the second end 31B of the actuating element 31 or single shape memory element.
  • said step c) is carried out by repeatedly activating the actuating element 31, so that the release means 21, in particular a small pump associated with a rod 21, is actuated multiple times in succession by the movable member 30; this allows to obtain a measured and metered release of the rinse aid agent contained in the container 20, suited to the type of wash program being executed.
  • said repeated activation of the actuating element 31 is obtained by repeatedly activating the electric circuit connected to the first end 31A and/or to the second end 31B of the shape memory element 31.
  • the washing agent dispensing device for a washing machine for household use in particular a dishwasher
  • the method of operation of said dispensing device and the related washing machine ensure that the washing agents are released into the wash liquid reliably and constantly over time.
  • washing machine itself to handle the delivery of a predetermined quantity of washing agents, in particular of a rinse aid agent, in an electronic and dynamic manner, without the user having to set said delivery beforehand (e.g. mechanically).
  • the repeated activation of the actuating element 31 allows to obtain successive actuations of the release means 21, in particular of a small pump associated with a rod 21, by the movable member 30. This in turn allows to obtain a metered release of the rinse aid agent contained in the container 20 as suited to the type of wash program being executed.
  • a further advantage of the dispensing device, of the method of operation thereof and of the washing machine for household use according to the present invention is that the implementation of a single actuating element 31, in particular a single shape memory element, for releasing both the detergent agent and the rinse aid agent lowers the production costs of the dispensing device 1 and hence of the washing machine; in addition, such a solution turns out to be particularly flexible and comfortable.
