Definitions

  • the present invention refers to a household dishwashing machine, comprising a door and a dispensing device of washing agents.
  • household dishwashing machines usually perform a plurality of different operation cycles or programs, which are selected by the user according to washing requirements.
  • dishwashing machines presently available in trade are usually equipped with the following wash programs:
  • All these programs (apart the soaking program) provide a main wash step, normally with hot water, which is mainly responsible for the quality of the whole wash program being selected.
  • both the "wash” and “hot rinse” steps are always performed adding special washing agents or rinse aids to be filled by the user in a suitable dispensing device; in some instances, also at least one of the "pre-wash” steps can be performed adding a washing agent.
  • the dishwasher can be provided with appropriate dispensing devices, which have separate compartments or tanks for containing various specific washing agents for the above steps of a wash program; typically, these washing agents consist of a solid washing agent, i.e. either a powder or in form of a tablet, dispensed during the wash step, and of a liquid additive, such as a rinse aid to be dispensed during the hot rinse step.
  • the washing agents dispenser usually comprises a body made from plastic material partially built-in in the dishwasher inner-door, i.e. the side of the front loading door of the machine facing inside the washing tub.
  • the above body delimits a compartment in its front area for containing a single dose of washing agent, required for executing the wash step; this compartment has a small cover, which is opened at the appropriate time of the wash cycle by the programming device of the machine; in this way, substantially at the beginning of the hot wash step, the entire single dose of solid washing agent is discharged into the washing tub.
  • a tank is also provided inside the dispenser body for containing a second liquid washing agent, typically a rinse aid; in general, the capacity of this tank is such to contain enough liquid agent to perform several wash cycles: thus, the machine user will only have to fill the tank periodically through an appropriate plug; the dispenser also has inside a small chamber associated to the above tank, for dosing the amount of rinse aid to be dispensed during a wash cycle; during machine operation, an actuator will be instructed by a programmer or timer to release a discharge outlet in line with the above dosing chamber, so the rinse-aid dose can flow down from the latter into the washing tub of the dishwasher.
  • a second liquid washing agent typically a rinse aid
  • the dispenser is formed to have the filling port of the compartment containing the washing agent facing upward when the machine door is open; therefore, after the door has been brought to a horizontal position, the user can fill the washing agent into said compartment, close its cover and then close the door again (with the door in this position the user is also able to fill the rinse-aid tank);
  • the cover of the compartment for the washing agent is usually a tilting or sliding type; its opening, at the appropriate time during the wash cycle for the washing agent to fall down by gravity into the tub is controlled by a programmer or timer of the machine.
  • some dispenser devices have an additional compartment, separated from the compartment containing the washing agent for the wash step.
  • the cover for closing the compartment of the washing agent will also extend to cover the additional compartment, but the latter has either front passages or located in its lower section: therefore, when closing the dishwasher door (i.e. bringing it from its horizontal position to a vertical position), most of the washing agent contained in the additional compartment will fall down by gravity into the washing tub and be used during the first pre-wash step.
  • this additional compartment is specifically used for containing the washing agent required to perform the first pre-wash step; therefore, the user has to fill with washing agent both the compartment for the wash step and the compartment for the pre-wash step.
  • Dispenser devices are also known, wherein the compartment of the single dose of washing agent for the wash step is fitted with ports ensuring a calibrated water inlet at the beginning of the wash cycle.
  • Washing machines are also known, wherein the loading door is not a tilting door but is linearly sliding on special guides; the solution described in FR-A-2.674.426 applies for specific reference to a dishwashing machine with two baskets; in other known solutions, the dishwashers have only one basket in the form of a sliding drawer for containing the crockery to be washed, whose front wall is actually the machine door.
  • the washing agents dispenser is fastened to the machine door or anyway to a wall or vertical surface delimiting the washing tub; as a result the dispenser is always laying on the same resting plane, independently from the open or closed condition of the door.
  • dispensers used on such machines must be fitted with a special electric pump for performing both the dosage and dispensing of the liquid washing agent.
  • these dispensers comprise a seat for housing a container open upwards, which is hinged on its bottom end and partially tilting.
  • the above container can be partially extracted from its seat inclining it out of the dispenser body for the intake of the washing agent dose; a reverse movement of the container takes it back to its relevant housing seat delimited in the dispenser body.
  • the present invention is also based on the acknowledgement that the above common art does not ensure adequate utilization of the single dose of washing agent loaded in the machine, i.e. optimal utilization of the capacity the latter may offer for improving washing quality.
  • reference CP indicates the inner-door of the dishwashing machine according to the present invention as a whole, i.e. the portion of the door usually consisting of a stainless steel shell, facing inside the washing tub of the machine.
  • Reference PI indicates a drawn area of the inner door CP, delimited in the upper section of the latter and protruding out on the front;
  • BS indicates an upper edge of the inner door CP, i.e. of the above drawn area PI.
  • the dispensing device of washing agents fitting the machine is mostly inserted inside the door, in particular in the drawn area PI; this dispenser is indicated in its whole with 1 in Fig. 1.
  • the upper section of the dispenser 1 indicated with ZS is directly facing out and protruding slightly on the upper edge BS of the inner door CP, through a port delimited in the edge; the lower section of the dispenser 1, indicated with ZI is overhanging below the drawn area PI, through a relevant port delimited in the latter; appropriate common sealing means are provided between the sections ZS and ZI and their relevant ports delimited in the inner door CP, of known type, for preventing water infiltration to the inner side of the machine door.
  • Fig. 1 also illustrate how in the above example, the upper section ZS of the dispenser 1 delimits three separate filling ports, namely:
  • the dispenser 1 has a manually operated tilting cover fitted with proper sealing means, indicated with CO in the Figures 2-4, being apt to shut simultaneously at least the ports AD and AP for the washing agent in solid form (powder or tablet); closure of the rinse-aid port AB is preferably obtained by means of a classic common plug indicated with TP in the Figures 2-4, which is anyway also covered by the above cover CO when the latter is in its relevant closed position.
  • the body of the dispenser 1 is inserted substantially goes through the drawn area PI of the inner door CP; thus, the lower section ZI of the dispenser 1 is directly facing inside the washing tub; to this purpose, as it will be seen later, discharge outlets are obtained in the portion ZI for the various washing agents contained in the dispenser 1.
  • the above dispensing device 1 is shown schematically in sections in the Figures 2, 3 and 4, in different operating conditions.
  • the dispenser 1 comprises a boxed body 2 from plastic material, wherein the following elements are delimited:
  • the compartment 3 communicates with the above filling port AD and has a lower discharge outlet indicated with 3A.
  • a dosing dispensing element indicated as a whole with 7 is assembled in the body 2 below the outlet 3A; in the example, the element 7 comprises a linear sliding element, wherein a through-cavity 7A is delimited; this cavity 7A being apt to contain an amount of washing agent volumetrically defined, equalling a portion or fraction of the single dose contained in the compartment 3.
  • the compartment 4 communicates with the above filling port AP and has a lower port 4A.
  • Reference 8 indicates a second movable element, which slides linearly between the dosing element 7 and the bottom wall of the body 2; this movable element 8 has a through-port 8A, whose functions will be further described.
  • References 9A and 9B indicate two discharge outlets delimited in the bottom wall of the body 2, i.e. in the section ZI of the dispenser 1 represented in Fig. 1, namely the portion extending out of the drawn area PI of the inner door CP.
  • the port 9A is so sized to extend both below the port 3A of the compartment 3 and below the through-port 8A of the movable element 8, when the dispenser 1 is in the rest condition illustrated in Fig. 2, for the purposes further described.
  • Fig. 2 shows how an end portion of the movable element 8 will extend in the compartment 4 partially shutting its lower outlet 4A, when the dispenser 1 is in its rest condition.
  • Reference 10 indicates a first common actuator, such as a thermal actuator, which has an operating shaft or piston 10A; the actuator 10 is commonly fastened inside the body 2 of the dispenser.
  • a first common actuator such as a thermal actuator, which has an operating shaft or piston 10A; the actuator 10 is commonly fastened inside the body 2 of the dispenser.
  • Reference 11 indicates a first lever pivoted on the body 2 at a location P1; the lever 11 has slots on both ends, wherein both the end of the shaft 10A of the actuator 10 and an extension 7B of the dosing element 7 are commonly engaged.
  • Reference 12 indicates a second common actuator, such as a thermal actuator, which has an operating shaft or piston 12A; also the actuator 12 is commonly fastened inside the body 2 of the dispenser 1.
  • Reference 13 indicates a second lever pivoted on the body 2 at a location P2; also the lever 13 has slots on both ends, wherein both the end of the shaft 12A of the actuator 12 and an extension 8B extending from an upright 8C of the movable element 8 are commonly engaged.
  • reference 14 indicates a rod coupled to said upright 8C of the movable element 8, which pertains to a rinse-aid dosing-dispensing system.
  • the dishwasher door is preferably fitted with common means for an intermediate stop of the angular movement of the door itself; these means consisting eventually of balls or pins, which are pushed by relevant springs for their partial extension out of the two side edges of the door, and are apt to engage in respective seats delimited in the side edges of the front access aperture to the washing tub of the machine; thus, when the door is closed, the above pins are capable of entering the above seats and keep the door steadily in a half-closed position, with the edge BS of the inner door CP facing upwards; a subsequent thrust on the door will release the above pins from their seats for complete closure of the door.
  • the above means ensuring a steady half-closed position of the door can be obtained through other common techniques; for instance, they may be integrated in the door hinging means to the machine cabinet.
  • the user Before starting a wash cycle, the user opens the dishwasher door and loads the crockery to be washed in the relevant baskets in the usual way.
  • the user can open the upper cover CO of the dispenser 1 and fill the single dose of washing agent for performing the cycle in the compartment 3 through the inlet AD; if required, the user can also remove the plug TP and fill the tank 5 with rinse aid through the inlet AB; the cover CO can be closed again after the likely closure of the plug TP.
  • the user will then close the dishwasher door and start the wash cycle.
  • the cavity 7A of the dosing element 7 in line with the same inlet 3A; in this operating position illustrated in Fig. 2, the cavity 7A is closed on its bottom by the upper surface of the movable element 8; thus, the cavity 7A can be filled with a defined amount of washing agent.
  • control system of the machine will instruct the device 1 for dispensing the washing agent.
  • the actuator 10 is supplied, so that its piston 10A to determine an angular movement of the lever 11 around the pivoting point P1 and the element 7 to move linearly to the right (with reference to Figures 2-4).
  • the cavity 7A is brought in line with the through-port 8A of the movable element 8, which is in line with the discharge outlet 9A; as a result, the amount of washing agent contained in the compartment 7A can freely fall down into the machine tub for the washing of the crockery. This condition is illustrated in Fig. 3.
  • the actuator 10 is deactivated so that its relevant piston 10A, lever 11 and dosing element 7 to go back to their original position of Fig. 2, where the cavity 7A can be filled with washing agent again through the port 3A; as it will be noticed, the return of the element 7 to its original position can be either obtained or favoured by common elastic means (e.g. integrated in the actuator 10).
  • the control system will instruct the actuator 10 of the device 1 again for dispensing a new portion of the detergent powder contained in the compartment 3; as it can be guessed, this occurs exactly as described above, i.e. a linear movement of the element 7 is produced until the cavity 7A is brought in line with the through-port 8A and then with the discharge outlet 9A; moreover, a new filling of the cavity 7A can be eventually obtained with the subsequent return of the element 7.
  • the number of supplies of the actuator 10 is preferably calculated according to the maximum capacity of the compartment 3, so as to ensure dispensing of nearly the total amount of washing agent at subsequent intervals as described above.
  • Dispensing of the final portion of detergent powder, vice-versa, is obtained supplying the actuator 12 through the control system of the machine.
  • the shaft 12A of the actuator 12 causes the lever 13 to perform an angular movement around the pivoting point P2; a linear translation to the left of the movable element 8 is obtained (with reference to Figures 2-4) with resulting thrust of the rod 14 toward inside the chamber 6 for dosing the rinse aid from the tank 5.
  • the through-port 8A is brought in line with the cavity 7A of the element 7 with the inside of the compartment 3 directly communicating inside the washing tub of the machine.
  • This condition is illustrated in Fig. 4.
  • the residual portion of washing agent eventually available in the compartment 3 can fall into the tub through the filling port 3A, the cavity 7A of the element 7, the through-port 8A of the movable element 8 and the discharge outlet 9A of the body 2.
  • the actuator 12 will remain supplied until a first dispensing of rinse aid is provided by the wash cycle of the machine.
  • the control system of the machine stops supply to the actuator 12, with a consequent return of the movable element 8 to the original position of Fig. 2; also in this instance, the return of the movable element 8 to its original position can be obtained or favoured by common elastic means, e.g. integrated in the actuator 12.
  • control system of the dishwasher is programmed for instructing a first dispensing of the washing agent already during a pre-wash step provided by the cycle, even if a cold one, in order to utilize the mechanical/abrasive features of the washing agent; this procedure will actually ensure a substantial soil removal since the first wash step, independently from water temperature.
  • control system of the machine can be programmed for a plurality of actuations of the device 1 in the subsequent main wash step, to obtain dispensing of portions or fractions of the washing agent at separate intervals.
  • washing agent can be dispensed within the same main wash step; for instance, a first dispensing will be conveniently performed at the beginning of this step, when the wash fluid has not yet reached the working temperature, and a second dispensing will be performed a certain time after that the same step has started, when the fluid temperature is assumed to have been reached (the attainment of this temperature may also be detected through appropriate sensing means); thus, the mechanical/abrasive features of the washing agent are fully utilized during the first part of the wash step (i.e. after a first dispensing) and during the second part of the wash step (i.e. after a second dispensing).
  • the steps for at least one dispensing of the washing agent and the steps for dispensing the washing agent at several intervals are established since the design stage of the control system of the machine, depending on the type of wash cycle type the user can select and the capacity of the compartment 3.
  • a plurality of rinse-aid dispensing actions can also be performed within one same rinse step and/or at least in the course of two different rinse steps.
  • the user of the dishwasher Before starting a wash cycle, the user of the dishwasher opens the machine door and loads the crockery to be washed in the appropriate baskets, in the usual way.
  • the user can bring the door to the above steady half-closed position, with the upper edge BS of the inner door CP facing upwards.
  • the user can open the cover CO and introduce the detergent tablet in the compartment 4 through the inlet AP; if required, the user can also fill the tank 5 with rinse-aid; then the cover CO can be closed again. The user will then finally close the dishwasher door and start the wash cycle.
  • the former When in the compartment 4 the detergent tablet is filled, the former will rest by gravity on the end portion of the movable element 8, extending inside the compartment 4 in line with its lower port 4A.
  • control system of the machine will supply the actuator 12 as previously described; in this event the residual portion of the tablet is finally dispensed (typically, this occurs strictly during the wash step of the cycle).
  • operation of the actuator 12 causes a linear translation of the movable element 8 to the left (with reference to Figures 2-4), with a consequent thrust of the rod 14 inside the chamber 6; through the same movement of the movable element 8, the port 4A of the compartment 4 is completely opened, so the residual portion of the detergent tablet will fall down through the discharge outlet 9B into the washing tub of the machine.
  • supply of the actuator 12 is maintained until the cycle provides for dispensing a first amount of rinse aid.
  • Fig. 5 is representing a possible embodiment of the rinse-aid dosing/dispensing system for the dispenser 1.
  • reference 5 indicates the rinse-aid tank and reference 6 the dosing chamber, as mentioned above.
  • a hollow cylindrical body 15 inside the chamber 6 is located a hollow cylindrical body 15, the inside of the latter communicates directly with the tank 5 through a port 16;
  • reference 17 indicates common sealing means operating between the chamber 6, the body 15 and the rod 14, to prevent the rinse-aid from running out of the body 15;
  • reference 18 indicates a plunger element solidly connected to the rod 14 inside the body 15.
  • the cylindrical body 15 also has a calibrated discharge outlet not visible in Fig. 5 on the rear of the plunger element 18, substantially in line with the port 16; said calibrated discharge outlet communicates with a discharge duct, not represented, in communication with the lower section of the body 2 of the dispenser 1, indicated with ZI in Fig. 1; it should noticed that also the inner part of the tank 5 is in communication with the lower section of the body 2 through a common venting duct, also not represented; the above ducts are conveniently in the form of a siphon.
  • the plunger element 18 With the system in rest condition as illustrated in Fig. 5, the plunger element 18 will keep both the port 16 and discharge outlet on the rear of the plunger element, in closed condition.
  • the rod 14 After actuation of the actuator 12 and the consequent movement of the element 8, as described above, the rod 14 is pushed inside the cylindrical body 15; following this movement, the plunger element 18 is gradually displaced to the left (with reference to Fig. 5), causing the port 16 and calibrated discharge outlet to open, and subsequently, a rinse-aid flow from the tank 5 inside the body 15, filling the latter.
  • the rod 14 is pulled out of the cylindrical body 15; following this movement, the plunger element 18 will gradually move to the right (with reference to Fig. 5), causing the rinse aid contained in the body 15 to flow in the relevant calibrated port and from here inside the washing tub through the above discharge duct.
  • the amount of rinse aid previously dosed by the cylindrical body 15 is dispensed.
  • the operating principle of the system illustrated in Fig. 5 works substantially like a "syringe", which permits, as previously mentioned, to perform a plurality of rinse-aid dispensing actions within one same rinse step and/or during at least two different rinse steps, through a supply sequence of the actuator 12.
  • the present invention obviously provides practical advantages for an easy use of the dishwasher.
  • a first essential advantage is an extremely comfortable filling operation of the various washing agents, which can be performed with the machine door half-opened due to the special position of the dispenser 1, its upper section ZS being in line with the upper edge of the inner door CP.
  • the dispenser represents a bulk inside the tub reducing its useful space; in this connection it should also be noticed how conventional dispensers, fitted with a movable cover, normally require a free space on their front for the opening of said cover.
  • the dispenser 1 is mainly built-in inside the machine door to remove any bulks inside the washing tub as well as the need of a free space on the front; it should also be noticed how most common inner doors already have an upper drawn section as previously indicated with PI.
  • dispensing device 1 comprising only one dedicated compartment 3 and/or 4 for the single dose of washing agent to be used; thus, the user is actually forced to use such a compartment for filling the whole single dose of washing agent required for performing the wash cycle, either in powder or in the form of tablets.
  • a portion of such a washing agent can be utilized during the first cycle step (first and/or second pre-wash), but requiring no specific decision by the user, who is not even required to perform additional operations than usually requested for common dishwashing machines.
  • the use of a single dose of detergent powder can also be optimised fractioning it in several doses volumetrically defined, which are dispensed at the most appropriate intervals of one same wash cycle.
  • a first fraction of the single dose of detergent powder can be utilized during a pre-wash step of the cycle; the device 1 will then allow dispensing a second fraction of the single dose of detergent powder also during a second pre-wash step of the cycle, provided it is included.
  • the device 1 also ensures a plurality of dispensing within one same step of the wash cycle; in this case, the control system of the machine will control dispensing of a third and fourth fractions of the single dose of detergent powder at separate intervals during the main hot wash step provided by the cycle.
  • the present invention also provides for adequate "diversified" utilization of a detergent tablet, i.e. the capability of utilizing portions of such a washing agent at subsequent intervals; the same applies for the rinse aid, which can be dispensed at several intervals.
  • a possible implementation provides a plate housing on the inner side of the inner-door CP (i.e. the opposite side to the side shown in Fig. 1) being apt to
  • section ZS and/or section ZI do not necessarily have to protrude outside the inner door CP, since they can simply face or be in line with the relevant ports delimited in the inner door itself, with relevant sealing means provided to hinder water infiltration inside the machine door.
