Definitions

  • the present invention relates to a water-conducting household appliance, in particular dishwasher, with a device for adding detergent in a limited space of walls washing compartment of the water-bearing household appliance, which has at least one spray system for cleaning items to be washed in the washing compartment, with a container arranged in the washing compartment for receiving detergent ,
  • a dishwasher with such a device in the form of an addition unit for adding detergent in a rinsing liquor known in which a liquid feed is provided in the addition unit for rinsing the cleaner from the addition unit.
  • a partial flow of the circulated rinsing liquor is conveyed via a valve and an additional line into the addition unit. Once the cleaner has been added, the line and the valve are without function until the program is restarted.
  • Object of the present invention is to provide a dishwasher with a device for detergent addition with high Aus Guessschreib.
  • a spray element is arranged adjacent to the container in the washing, which can be supplied via a line with rinsing water, in the adding device via a line with rinsing supplyable spray nozzle, and a first valve is provided for selectively activating the spray element and / or the spray nozzle.
  • the first valve is provided for blocking the supply line so as to enable a variable operation in which optionally only container is flushed out and simultaneously rinsing fluid is rinsed in addition to the rinsing of the container.
  • the first valve can be used to activate an additional spray element provided for cleaning items to be washed
  • the spray element may be part of the spray system. This is usually arranged in three levels in the washing compartment, for example in the form of rotatable spray arms or fixed nozzle systems.
  • the bypass line then ends, for example, at an additional nozzle of the spray system.
  • the additional spray element may also assist in flushing the detergent out of the container.
  • a further opening in the direction of the washing compartment can be provided in the container, which can be closed in particular before the addition of the detergent in the washing compartment.
  • rinsing liquor of the additional spray element can then also pass through the opening into the container.
  • the first valve is then switched so that the rinsing liquor during the rinsing process is passed to both the rinsing and the spray element.
  • the detergent can be completely rinsed out of the container in a shorter time.
  • the rinsing of the detergent from the container can therefore be supported by the additional spray element from the dishwasher.
  • an opening of the container has, at least temporarily, in the direction of the washing compartment.
  • more rinse liquor per unit time can reach the detergent for rinsing, whereby the rinsing process is accelerated and intensified.
  • at least a part of the container for example a wall or the bottom is movably mounted.
  • the movable part can be moved from a basic position to an additional position. In the basic position, the container is closed relative to the washing compartment so that the cleaning agent is protected from contact with the washing liquor.
  • the container In the supply position, the container is then open in the direction of the washing compartment, so that the washing solution can rinse the detergent into the washing compartment.
  • the movable part can initiate the flushing process when opening the container similar to a switch and terminate this when closing the container. This means that it is always possible to add just as much rinsing liquor to the cleaning agent as is necessary for its dissolution and rinsing.
  • the spray element may be, for example, a nozzle or a system of several nozzles. Both can be arranged fixed or movable in the washing compartment.
  • Spray element and emerging from the spray system rinse liquor thus serves to clean the items to be washed, while the rinse water emerging from the rinsing element for rinsing the detergent from the detergent addition device.
  • the dishwasher according to the invention pursues the concept that the elements provided for rinsing out the cleaning agent from the container can be used during an entire washing program. This avoids that the rinsing liquor stops in the lines over a longer period of time and can form deposits.
  • the rinse liquor supplied to the detergent addition can therefore first be conducted via the first valve into the adding device. There she meets the detergent, dissolves it and transports it to the dishwasher. After complete rinsing, the rinse liquor may then be passed to the additional spray element by switching the first valve to a bypass line on the feeder.
  • the additional spray element can then, for example, concentrate areas of the washing compartment which are not or only insufficiently reached by the remainder of the spray system.
  • the device according to the invention also has the advantage that the detergent addition can be done independently of the spray system through the Ausêtelement.
  • items to be washed which is arranged in front of the adding device, do not hinder the rinsing process.
  • the device according to the invention it is possible by the device according to the invention to admit partial amounts of the rinsing agent at different program times by corresponding activation of the valve.
  • the valve also allows a control in which the rinsing solution can be passed simultaneously both in the detergent addition device and in the bypass line. Depending on requirements, the amount of rinsing fluid flowing into the detergent adding device or into the bypass line can be controlled.
  • the container as a whole can be arranged to be movable, for example, in a housing open towards the washing compartment.
  • a side wall closes the cup-shaped or trough-shaped container in the direction of the washing compartment flush with the wall of the washing compartment or the housing.
  • the container is already filled in the basic position with detergent.
  • the side wall of the container facing the washing compartment prevents the ingress of Rinse liquor in the housing.
  • An additional cover for the protection of the cleaning agent can thus be dispensed with. Clogging, for example, of a powdered cleaning agent associated with a hindrance of the rinsing process or premature unfolding of the cleaning agent effect can thus be prevented.
  • the container or the part of the container from the basic position in the addition position are pivotable.
  • the container or the movable part of the container can be arranged to be displaceable along a curved path or rotatably supported. This form of storage is easy and inexpensive to produce.
  • the rotatable connection of the container with the housing can be carried out, for example, in the form of two pivot points left and right of the container bottom near the Spülraumwand in which two pins arranged on the container engage in corresponding recesses of the housing.
  • This form of storage allows the pivoting of the container out of the housing in the direction of Spülraum to a filling position. In the filling position, the interior of the container is accessible from the side of the washing compartment. In this position, the container can then be filled manually, for example by a user with detergent.
  • the limitation of the pivoting movement of the container in the direction of the washing compartment can be effected by stops which are arranged on the container and / or on the housing.
  • latching means can be arranged on the container, which interact with counter-latching means on the housing for latching the container with the housing in the basic position.
  • the movement of the container from the filling position to the basic position and the local fixation can - as well as the filling - automatically or programmatically controlled or done manually by a user.
  • all movements of the container or of a number of parts of the container can also be effected by an actuator, for example in the form of a motor, a coil or a bimetal.
  • the bimetal can, for example Depending on the temperature cause or cause the movement of the container. This is a purely mechanical control. When using a motor, this can be controlled by a control device, for example, program sequence-dependent, to then cause the movement of the container.
  • the supply of the rinsing liquor can also take place as a function of the movement of the container or of the container part between the basic position and the delivery position.
  • the position of the container in the supply position corresponds to that of the filling position.
  • a second valve for controlling the volume flow of the rinsing liquor can be arranged in the supply line, which is in operative connection with the container or the container part.
  • the movement of the valve actuator can generally be effected in response to the movement or position of the container or of the container part.
  • the second valve may for example be closed in the basic position of the container and be open in the supply position of the container. This ensures that only rinse liquor enters the container when it is open towards the dishwasher.
  • This can be realized, for example, with an actuator disposed on the container, which is in the addition position with the second valve in contact and then completely opens. During the movement of the container from the addition position to the basic position of the contact between the actuator and the valve is interrupted again and the valve is closed.
  • a sensor may also be used which detects the respective position of the container without contact and accordingly causes the opening and closing of the second valve by means of the control device. The opening and closing of the valve can be caused for example by electric actuators.
  • the second valve can be opened corresponding to the pivotal movement of the container between the basic position and the Ausêtdian. That means too too each pivotal position between the basic position and the supply position a corresponding position of the valve actuator is adjustable. Thus, not only two discrete but a number of settings exist between the open position and the closed position for the second valve. This makes it possible to even better dose the amount of rinsing liquor required for dissolving or rinsing out a certain amount of rinsing agent.
  • the coupling can be mechanical, electrical or sensory.
  • a mechanical coupling can be designed, for example, in the form of a linkage or a gearbox.
  • a potentiometer arranged at the pivot point of the container or container part can be connected to an electric actuator.
  • the movement or the pivoting position of the container or of the container part is detected by means of one or more sensors. These are connected for example via a control unit with the actuator of the valve.
  • the coupling makes it possible to adapt the amount of rinsing liquor required for rinsing the cleaning agent to the respective position of the container. In this way, the detergent can be evenly rinsed or dissolved. An abrupt flushing of the entire cleaning agent, which then dissolves completely in the washroom, can thus be avoided.
  • first and second valve instead of a first and second valve, only one valve can be provided that combines the functions of the two valves.
  • FIG. 1 shows roughly schematically the parts of a Spülflotten Vietnameselaufs 10 a dishwasher with a washing compartment 12 and arranged on or in a wall 13 of the washing compartment 12 adding device 14.
  • a spray system 16 with individual nozzles 18.
  • the spray system 16 is a Line 20 is connected to the pressure side of a circulation pump 22.
  • the pressure side of the circulation pump 22 is also connected via a line 24 to a first valve 26.
  • the first valve 26 is designed as a three-way valve, with a first connection 28 communicating via a line 32 with a spray nozzle 30 arranged in the adding device 14.
  • a second connection 34 of the first valve 26 is connected via a line 36 to a spray nozzle 38 arranged in the washing compartment 12.
  • a plurality of side walls 40, a bottom 42 and a ceiling element 44 form a container 46 for receiving a cleaning agent, not shown.
  • a drain opening 48 is arranged, which communicates via a line 50 with the washing compartment 12 in connection.
  • the circulating pump 22 sucks the rinsing liquor via an opening 54 in the bottom of the washing compartment 12 and conveys it both through the line 20 to the spray system 16, as well as through the line 24 to the first valve 26.
  • a control unit 56 causes the opening or closing of the ports 28 and 34 of the first valve 26.
  • the rinsing liquor can thereby either through the line 32 and the spray nozzle 30 into the container 46 of the Adding device 14 and / or through the line 36 and the spray nozzle 38 are conveyed into the washing compartment 12. Because the line 32 is completely deactivated after detergent addition, its length is as short as possible to avoid sedimentation by the wash liquor.
  • the valve 26 - in deviation from the illustration according to FIG. 1 - Be arranged directly in front of the spray nozzle 30.
  • the cleaning agent which is located in the container 46, 30 supplied via the spray nozzle rinse.
  • the detergent is dissolved in the wash liquor and rinsed with this through the drain opening 48 and the line 50 into the washing compartment 12.
  • the first port 28 is closed and the second port 34 is opened.
  • the rinsing liquor is then pumped only through the line 36 to the spray nozzle 38. With the spray nozzle 38 targeted areas of the washing compartment 12 are sprayed intensively, which are not or only insufficiently achieved by the spray system.
  • the control unit 56 transmits the signals necessary for controlling the valve 26.
  • the signal line between the control unit 56 and the valve 26 is symbolized by a broken line 57.
  • the connection 28 can still be kept open after the time provided for the addition of the detergent time, so that any remains of the detergent remaining in the container 46 can still be completely rinsed out of the container 46.
  • the connection 28 alone or together with the connection 34 can be fully or partially open. The rinsing liquor flow is thus split in percent on the terminals 28 and 34 and thus always in the lines 24, 32 and / or 36 in motion. Longer standing wash liquor and the associated risk of the formation of deposits in the lines 24, 32 and 36 is thus avoided.
  • FIG. 2 shows a second to the in FIG. 1 alternative embodiment. The same parts are therefore in FIG. 2 as well as in the Figures 3 and 4 with the already off FIG. 1 provided known reference numerals.
  • FIG. 2 In contrast to FIG. 1 has the in FIG. 2 shown adding device 14 a container 46 with movable bottom 42 which is pivotable by means of a hinge 43 between a container 46 downwardly closing or opening position. The direction of movement of the bottom 42 is symbolized by the arrow B.
  • a second valve 27 is disposed in the conduit 32 between the first valve 26 and the spray nozzle 30.
  • a sensor arranged on the swivel joint 43, like the valve 27, is connected to the control unit 56. The signal lines between the control unit 56 and the valves 26 and 27 or the sensor are symbolized by broken lines.
  • the sensor is a rotational position sensor, which transmits to the control unit 56 a signal which is associated with the respective pivoting position of the floor 42.
  • the control unit 56 determines a corresponding valve position and sends a corresponding signal to the actuator of the second valve 27.
  • the second valve 27 can be closed in the simplest case with the bottom closed 42 and opened with the bottom 42 open.
  • the control of the second valve 27 can also take place over the entire opening path or pivoting range of the floor 42.
  • the second valve 27 then has not only two discrete valve positions such as "open” and "closed” but a plurality of positions therebetween.
  • the volume flow of the rinsing liquor is then adjustable over the entire pivoting range of the floor 42 by means of the valve actuator.
  • FIGS. 3 and 4 a further embodiment of the adding device according to the invention is shown. Unlike the ones in the FIGS. 1 and 2 shown here is the entire container between a basic position ( FIG. 3 ) and an order ( FIG. 4 ) pivotable. In the supply position, the cleaning agent can be flushed out by one or more spray nozzles, which are arranged close to the adding device in the washing compartment.
