Abstract

The device ( 1 ) can be used in particular for the pivotable door of a dishwasher and comprises, in a structure or body ( 2 ) a first dispenser device ( 5, 6 ) for a washing agent, and a second dispenser device ( 4 ) for rinse agent, an electrically controlled actuator device ( 20, 21 ) connected to the first dispenser device ( 5, 6 ) in such a way that when the door is closed, a first excitation of the actuator device ( 20, 21 ) causes substantially only washing agent to be dispensed, and connected to the second dispenser device ( 4 ) by means of a transmission mechanism ( 22, 23 ) which includes a pivotable interconnecting element ( 23 ). The interconnecting element ( 23 ) is able to make the mechanism ( 22, 23 ) inoperative when the door of the dishwasher is opened, and to make it operative after a first excitation of the actuator device ( 20, 21 ) after the door has been closed. One end ( 23 a ) of this interconnecting element ( 23 ) is pivoted directly onto a movable control member ( 18 ) of the second dispenser device ( 4 ).

Claims (22)

1. An integrated dispenser device ( 1 ), in particular for a pivotable door of a dishwasher, comprising, in a structure or body ( 2 )

a first dispenser device ( 5 , 6 ) for washing agent and a second dispenser device ( 4 ) for a rinse agent,

an electrically controlled actuator device ( 20 , 21 ), connected to the first dispenser device ( 5 , 6 ) in such a way that when the door is closed, a first excitation of the actuator device ( 20 , 21 ) causes substantially only the washing agent to be dispensed, and connected to the second dispenser device ( 4 ) by means of a transmission mechanism ( 22 , 23 ) including a pivotable interconnecting element ( 23 ), in such a way that when the door is closed a second excitation of the actuator device causes the rinse agent to be dispensed;

the said interconnecting element ( 23 ) acting to make the said mechanism ( 22 , 23 ) inoperative when the door of the appliance is open and to make said mechanism operative after a first excitation of the actuator device ( 20 , 21 ) once the door is closed;

wherein the said pivotal interconnecting element ( 23 ) has one end ( 23 a ) which is pivoted directly onto a movable control member ( 18 ) of the second dispenser device ( 4 ).

2. A device according to claim 1 , in which the said transmission mechanism ( 22 , 23 ) includes a control lever ( 22 ) mounted rotatably in the said structure or body ( 2 ), and the position of which is controlled in operation by the actuator device ( 20 , 21 ), the said control lever ( 22 ) being a single arm lever, rotatable about an axis ( 11 ) passing through the end thereof which is opposite the rinse agent dispenser device ( 4 ) with respect to the actuator device ( 20 , 21 ).

3. A device according to claim 2 , in which the said control lever has a shaped portion ( 22 a ), with a blind recess ( 22 d ) and an adjacent through aperture ( 22 f ), and in which the interconnecting element ( 23 ) has a pin-like projection ( 26 ) at one end, the said projection cooperating in use with the recess ( 22 d ) and the said through aperture ( 22 f ) in the control lever ( 22 ).

4. A device according to claim 2 , in which the said control lever ( 22 ) has a stop projection ( 22 c ) against which the interconnecting element ( 23 ) abuts by gravity until the actuator device ( 20 , 21 ) is de-energized for the first time after the door of the appliance has been closed.

5. A device according to claim 1 , in which the movable control member ( 18 ) of the second dispenser device ( 4 ) is mounted inside the said structure or body ( 2 ) for translation along its own axis but without being rotatable about this axis.

6. An integrated dispenser device ( 1 ), in particular for a pivotable door of a dishwasher, comprising, in a structure or body ( 2 )

a first dispenser device ( 5 , 6 ) for washing agent and a second dispenser device ( 4 ) for a rinse agent,

an electrically controlled actuator device ( 20 , 21 ), connected to the first dispenser device ( 5 , 6 ) in such a way that when the door is closed, a first excitation of the actuator device ( 20 , 21 ) causes substantially only the washing agent to be dispensed, and connected to the second dispenser device ( 4 ) by means of a transmission mechanism ( 22 , 23 ) including a pivotable interconnecting element ( 23 );

the said interconnecting element ( 23 ) acting to make the said mechanism ( 22 , 23 ) inoperative when the door of the appliance is open and to make said mechanism operative after a first commutation of the actuator device ( 20 , 21 ) once the door is closed;

wherein the said interconnecting element ( 23 ) has one end ( 23 a ) which is pivoted directly onto a movable control member ( 18 ) of the second dispenser device ( 4 );

wherein said transmission mechanism ( 22 , 23 ) includes a control lever ( 22 ) mounted rotatably in the said structure or body ( 2 ), and the position of which is controlled in operation by the actuator device ( 20 , 21 ), the said control lever ( 22 ) being a single arm lever, rotatable about an axis ( 11 ) passing through the end thereof which is opposite the rinse agent dispenser device ( 4 ) with respect to the actuator device ( 20 , 21 ); and

wherein said control lever ( 22 ) has a stop projection ( 22 c ) against which the interconnecting element ( 23 ) abuts by gravity until the actuator device ( 20 , 21 ) is de-energized for the first time after the door of the appliance has been closed.

7. An integrated dispenser device ( 1 ), in particular for a pivotable door of a dishwasher, comprising, in a structure or body ( 2 )

a first dispenser device ( 5 , 6 ) for washing agent and a second dispenser device ( 4 ) for a rinse agent,

an electrically controlled actuator device ( 20 , 21 ), connected to the first dispenser device ( 5 , 6 ) in such a way that when the door is closed, a first excitation of the actuator device ( 20 , 21 ) causes substantially only the washing agent to be dispensed, and connected to the second dispenser device ( 4 ) by means of a transmission mechanism ( 22 , 23 ) including a pivotable interconnecting element ( 23 );

the said interconnecting element ( 23 ) acting to make the said mechanism ( 22 , 23 ) inoperative when the door of the appliance is open and to make said mechanism operative after a first commutation of the actuator device ( 20 , 21 ) once the door is closed;

wherein the said interconnecting element ( 23 ) has one end ( 23 a ) which is pivoted directly onto a movable control member ( 18 ) of the second dispenser device ( 4 ); and

wherein the movable control member ( 18 ) of the second dispenser device ( 4 ) is mounted inside the said structure or body ( 2 ) for translation along its own axis but without being rotatable about this axis.
