Definitions

  • the present invention relates to a dishwasher of the type comprising a washing container for accommodating the dishes to be washed, a spraying device for spraying a washing liquid onto the dishes arranged in the washing container, and a detergent container for dispensing detergent during the wash cycle of the dishes.
  • Dishwashers are known with a detergent container, formed in the door of the dishwasher, which can be opened and closed by a cover.
  • a dose of detergent into the detergent container (the volume of which is dimensioned to contain only one dose of detergent) and manually closes the cover, which remains closed by virtue of a snap-lock system.
  • a wash cycle starts during which an actuator disengages the restraining system of the cover. In this manner, the entire content of the detergent container is poured into the washing container, in which it mixes with the water which is recirculated and sprayed onto the dishes.
  • the dishwashers of the prior art the user must load the detergent before each wash cycle and manual dosing a very small amount of powder or liquid, as precisely as possible, which activity is perceived as intrinsically annoying and sometimes difficult, in particular for elderly people. Furthermore, the fact that the dishwasher detergent must be stored out of the reach of children, and therefore is often placed in very high cabinets, which can be reached only by climbing onto a chair or onto a ladder, must also be taken into account.
  • US 2006059958 A1 discloses a detergent dispenser system in which a dispensing valve is provided for fluidly connecting to a detergent supply container.
  • US 2009000644 A1 discloses a method for metering active substances in a dishwasher.
  • EP 1228736 A2 describes a household dishwashing machine with dispensing device of washing agents and wash program thereof.
  • WO 2009/033828 A1 describes a metering system for dispensing flowable or dispersible preparations.
  • a dishwasher comprises:
  • the detergent container can be filled less frequently, e.g. once a week or a month, with a large amount of detergent, without the user being burdened by the need to accurately dose at all, and the dishwasher can be used for a given period of time and for a given number of washes without needing to refill or dose the detergent.
  • the dosing device actuated automatically during the wash cycle, the user only needs to load the detergent, but no longer dose it for the single wash cycle.
  • a dishwasher 1 comprises a washing container 2 adapted to accommodate dishes 3 to be washed and which can be closed by a door 4.
  • At least one spraying device is positioned inside the dishwasher 1, e.g. a spraying arm 5 rotatably mounted in the washing container 2 and forming a plurality of spraying nozzles 6 for spraying a washing liquid onto the dishes 3 accommodated in the washing container 2.
  • a pump 7 is hydraulically connected, e.g. by means of a delivery pipe 8, to the spraying arm 5 for feeding the washing liquid to the spraying nozzles 6.
  • the dishwasher 1 also comprises a heating device 9, adapted to heat the washing liquid, e.g. an electric resistor arranged in a collection tank 10 of the washing liquid.
  • the collection tank 10 preferably formed in a lower zone of the washing container 2 or under the washing container 2, is connected to the pump 7 to allow the drawing of the either cold or heated washing liquid needed for washing the dishes 3.
  • the collection tank 10 and/or the pump 7 are further connected to an inlet valve 11 for loading network water, and to a discharge duct 12 for discharging the washing liquid.
  • the inlet valve 11 is placed in a supply conduit 36 which can be connected to the water network and which forms an air break 37 to prevent drawing back of liquid into the water network and passes through a water softener device 38 (decalcifier) before opening into the washing container, in particular into the collection tank 10.
  • a water softener device 38 decalcifier
  • Dishwasher 1 further comprises a detergent container 14 forming an inner space 15 for containing a detergent 16 (powder or liquid), a dispensing opening 17 for dispensing detergent 16 from the inner space 15 towards the washing container 2, and a shutter member 18 for opening and closing the dispensing opening 17.
  • a detergent container 14 forming an inner space 15 for containing a detergent 16 (powder or liquid), a dispensing opening 17 for dispensing detergent 16 from the inner space 15 towards the washing container 2, and a shutter member 18 for opening and closing the dispensing opening 17.
  • a control device e.g. an electronic control board 13 is configured to allow the selection of a dish treatment program from a plurality of treatments programs, and controls the actuation of the pump 7, of the heating device 9, of the inlet valve 11 and of a dispensing actuator 20 acting on the shutter member 18.
  • the inner space 15 of the detergent container 14 is sized to accommodate a total volume of detergent sufficient for a plurality of wash cycles
  • the dishwasher 1 further comprises a dosing device 19 in communication with the dispensing opening 17 and which can be activated by means of the dispensing actuator 20 for dosing and dispensing, during a single wash cycle, a partial volume of detergent 16 for said single wash cycle.
  • the dosing device 19 is actuated automatically during the wash cycle, the user only needs to load the detergent, but no longer dose it for the single wash cycle.
  • the detergent container 14 can be either extracted or removed from the dishwasher 1 to facilitate its filling.
  • the dishwasher 1 forms a coupling seat 21 for a removable mechanical connection, e.g. snap-locking or bayonet, of the detergent container 14 and for a connection of the dispensing opening 17 into communication with a dispensing conduit 22 communicating with the inside of the washing container 2.
  • the coupling seat 21 may be formed in a side wall 23 of the washing container 2, e.g. in the inner surface of the door 4 ( figure 7 ).
  • the detergent container 14 forms a loading opening 23 (in addition to the dispensing opening 17) for pouring detergent 16 into the inner space 15 of the detergent container 14.
  • the loading opening 23 is preferably larger than the dispensing opening 17 to facilitate and speed up the filling of the detergent container 14 and to facilitate an airtight seal of the smaller dispensing opening 17 by means of the shutter member 18.
  • the loading opening 23 can be opened and closed by a cover 24 (possibly provided with a seal) which can be directly and permanently connected (e.g. hinged or inserted in the form of a gate valve) to the detergent container 14 (so that it cannot be lost but can easily be washable and repairable).
  • the cover 24 may be provided as fully detachable component and therefore more easily replaceable.
  • the cover 24 may be formed or connected to the coupling housing 21 so as to close the loading opening 23 when the detergent container 14 is coupled to the coupling seat 21 so as to free the loading opening 23 when the detergent container 14 is detached from the coupling housing 21. This reduces the number of components and the number of operations required for loading the detergent.
  • the dispensing opening 17 is formed on a lower side of the detergent container 14, so as to facilitate the dispensing of the detergent 16 by virtue of the force of gravity.
  • the loading opening 23 may be formed on an upper side of the detergent container 14, opposite to the dispensing opening 17, to facilitate the connection and the movement of the loading cover 24 and of the shutter member 18 without mutual encroachments.
  • the dispensing opening 17 may be formed in the loading cover 24 with the advantage of being able to make the base body of the detergent container 14 with a single opening.
  • the shutter member 18 may comprise:
  • the shutter member 18 can be coupled to the dispensing opening 17 and can be displaced with respect to the dispensing opening by means of the flow actuator 20 to allow and prevent the release of detergent 16 from the dispensing opening 17 in controlled manner.
  • the shutter member 18 may be permanently and elastically urged into a closed position (e.g. by means of a spring 35, figure 5 ) to ensure the airtight seal of the dispensing opening 17 when the detergent container 14 is detached from the dishwasher and/or when the dispensing actuator 20 is deactivated.
  • the shutter member 18 may be shaped and displacable so as to always block the passage of detergent when the shutter member 18 stops immobile in any one position, and so as to allow the passage of detergent or even convey the detergent, when the shutter member 18 is moved with respect to the dispensing opening 17.
  • Examples of this latter embodiment are ball or piston or box shutters having one or more cavities adapted to receive a limited quantity of detergent when they are facing and communicating with the dispensing opening 17 and to release this limited amount of detergent when they are displaced out of communication with the dispensing opening 17.
  • the dosing device 19 delimits a dosing space 25 which is much smaller than the inner space of the detergent container 14, and which can be switched (displaced or connected) by means of the dispensing actuator 20:
  • the dosing space 25 may be formed in a dosing container 26 which is either distinct or separate from the shutter 20 and possibly installed permanently in the dishwasher 1. This makes it possible to make the dosing container 25 independently from the detergent container 14 and to couple it easily and permanently with the dispensing actuator 20 (without needing to make a detachable coupling) in addition to not exposing the dosage compartment 26 to handling and to the consequent risk of displacement or damage, by the user.
  • the dosing space 25 may be formed directly in the shutter member 18, thus reducing the number of individual components to be made and to move, at the cost of greater complexity of the shape of the shutter member 18.
  • the dosing space 25 can be switched (displaced or connected) by means of the dispensing actuator 20 into communication with the water feed conduit 36 to completely empty the dosed detergent 16, to wash the dosing space 25 and to achieve an intense mixing of the detergent 16 with the washing liquid ( figure 9 ).
  • the volume of the dosing space 25 may be adjustable to adapt the dosed amount of detergent 16 to the wash cycle conditions, to the user's preferences or to the type of detergent used.
  • the volume of the dosing space 25 can be adjusted by either displacing or deforming at least one wall 27 delimiting the dosing space 25, e.g. by means of the same dispensing actuator 20.
  • the partial volume of detergent 16 for the single wash cycle is adjustable, preferably in automatic manner, e.g. by adjusting the number of actuations of the dosing device 19 and/or by adjusting the volume of the dosing space 25 and/or by adjusting the number of switches of the dosing space 25 into communication with the dispensing opening 17 and with the dispensing conduit 22.
  • the dispensing actuator 20 may comprise a single actuator controlled by the control unit 13, which moves the shutter member 18, switches the dosing space 25 and, if provided, adjusts the volume of the dosing space 25, e.g. a linear actuator (linear motor, solenoid), rotary actuator (electric motor) or roto-translating actuator (linear electric motor and rotary switch assembly).
  • a linear actuator linear motor, solenoid
  • rotary actuator electric motor
  • roto-translating actuator linear electric motor and rotary switch assembly
  • Figure 10 shows an example of a linear and rotary flow actuator 20 which displaces the shutter member 18 and the dosing container 26 by means of the linear motion and displaces the wall 27 of the dosing container 26 by means of the rotational movement and a worm screw mechanism 28 to adjust the volume of the dosing space 25.
  • the dispensing actuator 20 may comprise a plurality of single actuators controlled by the control unit 13, which move the shutter member 18, switch the dosing space 25 and, if provided, adjust the volume of the dosing space 25, e.g. one or more linear, rotary or roto-translating actuators.
  • the dosing device 19 may be permanently fixed to the detergent container 14 and detached together with it from the dishwasher 1.
  • the dosing device 19 can be permanently fixed in the dishwasher 1.
  • a layer of temperature-insulating material 29, for example a single or multiple air gap or foam material is advantageously provided between the inner space 15 of the detergent container 14 and the inner space of the washing container 2 and/or a cooling system 30, e.g. a cool water conduction system, in heat exchange relationship with the inner space 15 of the detergent container 14 ( figure 7 ).
  • the dishwasher 1 comprises a system 31 for detecting the quantity of dishes 3 and/or of the dirt intensity of the dishes 3 arranged in the washing container 2, and the control circuit 13 adjusts the partial volume of detergent 16 for the single wash cycle according to the quantity of dishes 3 and/or the dirt intensity detected.
  • the detecting system 31 may comprise a temperature sensor 32 of the washing liquid, connected to the control circuit 13, which control circuit 13 calculates a temperature gradient during the heating of the washing liquid, said temperature gradient being indicative of the mass and thermal capacity of the dishes 3.
  • the detection system 31 may comprise a washing liquid turbidity sensor 33 (e.g. optical), connected to the control circuit 13, said detected turbidity being indicative of dirt of the dishes 3.
  • the turbidity sensor 33 and/or the temperature sensor 32 may be positioned in the collection tank 10.
  • the detergent container 14 and the dosing device 19 are provided in addition to, and preferably distanced from, a rinse-aid container and doser 34.
  • Figures from 2 to 6 show the function of dispensing and dosing of the detergent 16.
  • the shutter member 18 With the detergent container 14 engaged with the coupling seat 21, the shutter member 18 is engaged by a coupling portion 40 of the dosing container 26 so as to be displacable together between:
  • the dosing space 25 fills with detergent 16.
  • the dispensing opening 22 is closed again and the dosing space 25 releases the volume of detergent 16 precisely dosed.
  • the used detergent is a liquid detergent, a powder detergent or a granular detergent.
