Abstract
Description
- The present invention refers to a multi-dose dispenser of liquid additive products for washing machines, in particular a dispenser of rinsing aid for dishwashing machines.
- The need is largely known to exist in modern household dishwashing machines for a multi-dose kind of dispenser to be provided, which is capable of delivering into the washing vessel appropriately metered amounts of rinsing aid, which is usually in the form of a viscous liquid with a high foaming capacity, during different phases of a same operation cycle of the machine. For example, it is appropriate for a dose of rinsing aid to be dispensed not only during a rinsing phase preceding the final drying of the washload items, but also during the actual washing of the same washload items in view of improving the soil removal effect.
- To such a purpose, the dispenser shall not only have a sufficient holding capacity to dispense an adequately high number of doses, but must also be capable of accurately metering each single dose of liquid additive. Accordingly, the dispenser must include a multi-dose reservoir for storing said adequate amount of liquid additive, as well as means adapted to repeatedly measure and deliver the same additive in the form of volumetrically metered amounts. The solution consisting in the rinsing aid being metered through a time-controlled delivery is in fact quite out of the question, since the density of the rinsing aid itself is strongly variable depending on the different operating temperatures and the different kinds of additive used.
- On the other hand, since the loading door of the dishwashing machine cannot be opened during an operation cycle of the machine, such a volumetric metering cannot be accomplished by having resort to a traditional "decanting" or pouring-off system, i.e. by making use of a simple dispenser of the type that is mounted on the door of the machine and is adapted to decant, i.e. pour into a volumetric metering chamber, each time that the door of the machine is opened and closed again, a corresponding amount of rinsing aid stored in a multi-dose reservoir.
- In an effort to reconcile these contrasting needs, the proposal has been made of providing the rinsing aid dispenser with a multi-dose rinsing-aid reservoir whose bottom is in communication, via a filling aperture, with a volumetric metering chamber situated therebelow, the bottom of which is in turn capable of communicating fluidly with the washing vessel of a washing machine via a dispensing aperture. A moving double-shutter member controlled by an electromagnet is adapted to be switched between a first and a second position, in which it shuts the sole filling aperture and the sole dispensing or delivery aperture, respectively.
- In said first position, the liquid additive stored in the reservoir is allowed to flow by gravity to fill said metering chamber, whereas in said second position the amount of liquid additive contained in the metering chamber is allowed to be dispensed, i.e. delivered into the washing vessel, by gravity.
- This solution, although advantageously simple thanks to the use of a single actuator member, has anyway a drawback in that, when said moving shutting member is being switched over to said first and said second positions, both the filling aperture and the dispensing aperture are temporarily open at the same time, actually, with the result that an uncontrolled amount of liquid is able to flow out from the dispenser through said two apertures arranged in series. This can alter to a substantial extent the actual dose of additive being dispensed each time, especially in the case that the shutting member is such as to switch over in a relatively slow manner.
- It therefore is a main purpose of the present invention to provide a multi-dose dispenser of liquid additives for washing machines, which has a particularly simple and reliable structure and is at the same time capable of ensuring a particularly accurate volumetric metering of said additives without any need for a system of the afore mentioned "decanting" kind to be implemented.
- A further purpose of the present invention is to provide a multi-dose dispenser of liquid additives of the above cited kind, which is capable of operating correctly and in an accurate manner without any electrically energized actuating means being actually required to ensure the operation of said dispenser.
- According to the present invention, these and further aims are reached in a multi-dose dispenser of liquid additives for washing machines incorporating the characteristics as recited and defined in the appended claims.
- Anyway, features and advantages of the present invention may be more readily understood from the description that is given below by way of nonlimiting example with reference to the accompanying drawings, in which:
- Figures 1 to 3 are schematic views of a first embodiment of the additive dispenser according to the present invention, in respective operating positions thereof; and
- Figures 4 to 6 are schematic views of a second embodiment of the additive dispenser according to the present invention, in respective operating positions thereof.
- With reference to Figures 1 to 3 above, the additive dispenser can be contained within a
housing 1 which accommodates at least areservoir 2 adapted to be filled, via an appropriateupper aperture 3, with a substantial multi-dose amount of liquid additive, such as for instance a rinsing aid for dishwashing machines. - The bottom of the
reservoir 2 is capable of fluidly communicating, via afilling aperture 4, with avolumetric metering chamber 5 situated therebelow, which in turn comprises, in the bottom thereof, anaperture 6 for dispensing such an additive. The latter can then be delivered into the washing vessel of the dishwashing machine via anaperture 7 provided in the bottom of thehousing 1. - The
filling aperture 4 and the dispensingaperture 6 are associated torespective shutter valves - The
valve 8 is connected to areturn spring 10 of the cap or similar type, or the like, which normally keeps it at a distance from theaperture 4, which is therefore open in the resting position thereof shown in Figure 1. - The
valve 9 is in turn associated to athrust spring 11, or the like, which normally keeps it in a position in which it closes theaperture 6. - The
valves actuator 12, which may be of an electromagnetic kind or - preferably - of a thermally actuated kind. - The
actuator 12 comprises a movingmember 13 adapted to act on thevalves lever 15 that is provided withrespective pushing means return spring 17 keeps said pushingmeans lever 15 in a condition in which they are substantially disengaged from thevalves - As a result, in the resting position illustrated in Figure 1, the liquid stored in the
reservoir 1 is able to flow by gravity into themetering chamber 5, thereby filling up the inner volume thereof. - When the
actuator 12 is then operated, the movingmember 13 thereof moves to act on thelever 15, by overcoming the force of thereturn spring 17, to bring thepushing means respective valves pushing means 14 brings thevalve 8 into closing theaperture 4, by overcoming the force of thereturn spring 10, whereas thevalve 9 keeps being closed. In this manner, the occurrence of a transient condition in which bothapertures reservoir 2 via thechamber 5, is effectively avoided. - It is just in the subsequent portion of the displacement travel of the lever 15 (Figure 3) that the pushing means 15 comes to engage the
valve 9 to open theaperture 6, by overcoming the force of therespective return spring 11. At this point, the volumetrically metered amount of liquid that had previously filled up thechamber 5 flows out of said chamber by gravity via thedispensing aperture 6. - In order to facilitate such a dispensing, said
metering chamber 5 may be provided with avent pipe 18. - When the
actuator 12 is deactivated, in a per se known manner, thereturn spring 17 causes thevalve 9 to move back into the position in which it closes the dispensing aperture 6 (Figure 2) and thereturn spring 10 then causes thevalve 8 to move back into its resting position in which it disengages from the aperture 4 (Figure 1). It is just and solely at this point that the liquid stored in thereservoir 2 is able to flow and fill by gravity themetering chamber 5, thereby preventing it from flowing out through theaperture 6 as thevalves - In conclusion, such a differentiated actuation of the
valves apertures actuator 12 is of the thermally operated kind, which has on the one hand the advantage of not requiring any power-supply connection, but, on the other hand, is only capable of ensuring relatively slow changing-over operations. - It shall be appreciated that the above described liquid-additive dispenser may be the subject of a number of modifications without departing from the scope of the present invention.
- For instance, according to the embodiment illustrated in Figures 4 to 6, the
volumetric metering chamber 5 may be provided in correspondence of apiston 19 that is capable of sliding tightly with respect to acylinder 20 arranged below thereservoir 2. In particular, themetering chamber 5 is delimited within thecylinder 20 by two head-walls cylinder 20 throughrespective sealing rings - In the embodiment illustrated in Figures 4 to 6, the
filling aperture 4 and the dispensingaperture 6 are provided in correspondence of the side surface of thecylinder 20 and the axial distance from each other is equal to or greater than the axial distance of the two head-walls metering chamber 5 is in communication with themulti-dose reservoir 2 via theaperture 4 and, therefore, is able to fill up with liquid additive, thanks also to the provision of thevent tube 18. - The
piston 19 is capable of being operated by theactuator 12 via aconnection 25 provided with areturn spring 17. When theactuator 12 is operated, the movingmember 13 thereof acts on saidconnection 25 so as to cause thepiston 19 to slide towards a lower end-of-stroke, until the dispenser is brought into the transient condition illustrated in Figure 5. In this condition, thewalls apertures metering chamber 5, with respect to which they are in fact closed. Also in the case of the embodiment of the invention, therefore, the occurrence of a transient condition in which bothapertures reservoir 2 via thechamber 5, is effectively avoided. - It is just in the subsequent portion of the displacement stroke of the piston 19 (Figure 6) that the
aperture 6 is axially passed beyond and cleared by thewall 22, thereby establishing a communication with themetering chamber 5. At this point, the volumetrically metered amount of liquid that had previously filled up thechamber 5 flows out of said chamber by gravity via the dispensingaperture 6 itself. - When the
actuator 12 is deactivated, thepiston 19 slides back into its resting position shown in Figure 4 by passing through the transient position shown in Figure 5. - Therefore, the
apertures aperture 4 is then cleared axially by thewall 21 of thepiston 19 passing therebeyond, so that it is now able to communicate with themetering chamber 5. It is just and solely at this point that the liquid stored in thereservoir 2 is able to flow by gravity to fill up themetering chamber 5, thereby preventing it from flowing out through theaperture 6 as thewalls piston 19 are moving during a change-over stroke thereof. In this case, it can be appreciated that said piston walls are substantially equivalent to thevalve members - Also in the case of the embodiment illustrated in Figures 4 to 6, therefore, in which the
walls apertures - It will of course be readily appreciated that some of the features of the two afore described embodiments of the present invention may be appropriately combined in a variety of manners, according to the needs.
