Definitions

  • the present invention relates to dishwashing machines, and in particular to a multidose dispenser suitable to dispense detergent in a plurality of washing cycles.
  • a dishwasher includes inside the door a dispenser substantially consisting of a basin that, when the door is open in the horizontal position, is loaded by the user with the detergent required for the washing cycle and then closed by a lid hinged thereto which is engaged by a latch, said lid being biased open by a spring. In this way it is possible to close the dishwasher door without the detergent falling out of the basin, which will then be opened at the right moment in the cycle by releasing the lid latch.
  • a first simple solution proposed since some time ago is that of a dispenser provided with a reservoir suitable to contain an amount of detergent sufficient for various cycles, as well as with detergent dosing and feeding means such as a roller divided into compartments or a screw feeder.
  • a dispenser provided with a reservoir suitable to contain an amount of detergent sufficient for various cycles, as well as with detergent dosing and feeding means such as a roller divided into compartments or a screw feeder.
  • detergent dosing and feeding means such as a roller divided into compartments or a screw feeder.
  • Examples of said dispensers are found in the publications WO 82/00482, EP 1228736 and EP 1236430 but they are particularly suitable for use with liquid detergents such as those used in washing machines.
  • powdered detergents tend to lump and clog the dispenser due to the temperature and humidity conditions of their storage in the reservoir, which is necessarily close to the washing tank.
  • liquid detergents it is not advisable to use liquid detergents in dishwashers since they have the disadvantage of not providing the same washing performance of powders, given that certain essential components cannot be liquefied and/or do not remain in suspension.
  • the object of the present invention is to provide a multidose dispenser which is free from the above-mentioned drawbacks. This object is achieved by means of a multi-compartment mobile dose-meter that is progressively extracted from a protective shell, to be exposed to the washing action of the sprinkler same as the conventional basin.
  • Other advantageous features of the present dispenser are disclosed in the dependent claims.
  • a first great advantage of the present dispenser is that it is extremely reliable, in that even if the detergent lumps the dispensing mechanism remains unaffected and the sprinkler can wash the detergent away into the washing liquid.
  • a second significant advantage of this dispenser is that it can be used with any type of detergent, namely powdered, liquid or in tablets.
  • a further advantage of the above dispenser stems from its compact size which allows to arrange it in the dishwasher door same as the conventional basin dispenser. As a consequence, it is easily applicable to any model of dishwasher without requiring particular changes to the structure of the machine and/or to the arrangement of the components thereof, since the only changes are those made to the door.
  • a multidose dispenser for dishwasher consists of a body 1, in which there is inserted a dosing member 2 divided into a plurality of compartments (six in the illustrated example) by dividing plates 3 each of which is provided with a relevant peripheral gasket 3'.
  • Body 1 has at one end a detergent load bay 4, closed by a relevant spring-loaded lid 6, and at the other end a protective shell 5, both these members having substantially the same length of dose-meter 2.
  • the dosing member 2 is movable between bay 4 and shell 5 by means of a pair of threaded bars 7 engaging corresponding internally threaded tubes 7', the dividing plates 3 being mounted on said tubes 7'.
  • the rotation of bars 7 is controlled by an electric motor 9 through suitable reduction gears 8.
  • a slot 10 is provided between body 1 and shell 5, whereby possible residues that remain inside shell 5 are expelled upon retraction of dose-meter 2.
  • the dishwasher door When the dishwasher door is open in the horizontal position with dose-meter 2 completely empty and positioned in the load bay 4, as shown in fig.2, the user pours into the compartments of dose-meter 2 the liquid or powdered detergent (or places a package-free tablet in each compartment) and then closes lid 6, as shown in fig.3.
  • the control unit of the machine activates motor 9 which drives bars 7 into motion and dose-meter 2 is drawn inside shell 5, with each compartment containing the dose of detergent poured therein.
  • Gaskets 3' allow the use of liquid detergent in that they seal along the whole periphery, and they also guarantee that the detergent in powder or tablet is not reached by significant water or moisture.
  • motor 9 is activated at the defined phase to push dose-meter 2 out of shell 5 by a distance equal to the length of a compartment, so that the compartment which must be emptied is outside shell 5 and the adjacent compartment on the contrary remains completely inside shell 5.
  • Lid 6 is then released so as to drop in the washing tank the detergent contained in the exposed compartment.
  • the dispenser is arranged on the door in the same position of the conventional dispenser, namely at the sprinkler of the upper rack, also the mechanical action of the washing jets helps to thoroughly remove from the dispenser the detergent that, in particular when powdered, tends to stick to the sides of the compartments.
  • dose-meter 2 will be pushed out at the right moment so as to expose the second compartment, and so on for six washing cycles before the user needs to reload the dispenser. Furthermore, it is possible to provide a system to indicate to the user the need to load the dispenser prior to the cycle start or the number of remaining range cycles, as well as other possible operation problems of the dispenser such as the missed delivery of the correct dose of detergent due to lacking or incomplete loading of dose-meter 2.
  • the above-described and illustrated embodiment of the dispenser according to the invention is just an example susceptible of various modifications.
  • the number, shape and arrangement of the compartments of dose-meter 2 can be changed according to the needs, as well as the actuator means which provide the movement thereof.
  • the threaded type of coupling could be replaced by a rack system, or by a piston or other equivalent mechanism.
