Definitions

  • the invention relates to a method for monitoring the function of a spray arm arranged in a washing compartment of a dishwasher.
  • the invention relates to a dishwasher, in particular a domestic dishwasher, with a washing compartment providing a washing compartment, which has a loading opening which can be closed in a fluid-tight manner by means of a pivoting washroom door, with a spray arm which is rotatably arranged in the washing compartment and with a metering opening provided, preferably on the inside of the washing compartment door, which is used to feed cleaning agents into the wash cabinet.
  • Dishwashers of the type mentioned at the outset are well known per se from the prior art, also in the particular embodiment as domestic dishwashers. A separate printed proof is therefore not required at this point.
  • Dishwashers of the generic type have a washing compartment providing a washing area. This is accessible on the user side via a loading opening which can be closed in a fluid-tight manner by means of a pivotably mounted wash cabinet door.
  • the washing container serves to hold items to be cleaned, which can be, for example, dishes, cutlery and / or the like.
  • the dishwasher has a spray device in the interior of the washing container for the application of washing liquid, the so-called washing liquor, to items to be cleaned.
  • This spray device typically provides rotatably mounted spray arms, two or three such spray arms being provided as a rule. When used as intended, the items to be cleaned are exposed to washing liquor by means of rotating spray arms.
  • process chemicals are used that are fed into the wash cabinet during a wash and / or drying process.
  • Process chemicals of this type are, in particular, cleaning chemicals that are fed to the wash cabinet in a program-controlled manner.
  • Solid cleaning agents can be in pourable powder form or as so-called tabs, i.e. in tablet form. Practice has shown, however, that the best cleaning results can be achieved with pourable cleaning agents in powder form.
  • dishwashers known from the prior art typically have a storage container on the inside of the door, which is to be filled with a manually determined amount of cleaning agent before a program is started. During a program sequence, this storage container opens at a certain point in time of the washing program and the cleaning agent stored in the storage container can be flushed out by the washing solution located in the washing area of the dishwasher.
  • dosing units In order to be able to carry out a detergent supply for a plurality of cleaning cycles to be completed, that is to say cleaning programs, so that manual detergent dosing does not have to take place before the start of each cleaning program, dosing units have been proposed, for example with the DE 10 2013 104 391 A1 .
  • A1 known metering unit has a metering device.
  • This dosing device is equipped with an exchangeable storage container, which is used to store cleaning agent in an amount that is sufficient for a plurality of individual cleaning programs.
  • the amount of detergent intended for a proper execution of a cleaning program is removed from the storage container under program control and supplied to the washing area of the dishwasher.
  • the dosing unit is connected to a unit that opens into the washing area Connected dosing opening, via which a portion-wise introduction of detergent into the wash cabinet takes place in the case of dosing.
  • the in the DE 102015120412.6 Dishwasher described at least one of the spray arms of the spray device via a spray nozzle that interacts with the metering opening in a targeted manner.
  • unwanted cleaning agent adhesion is avoided or any cleaning agent residues that may have remained from a previous washing program step are removed.
  • the metering opening and the discharge channel opening into the metering opening are kept free from cleaning agent residues, in particular incrustations and / or adhesions.
  • the DE 102008003883 A1 as well as the DE 4020898 A1 each disclose a method for detecting the rotation of a spray arm of a dishwasher by means of an optical sensor.
  • the invention proposes a method having the features of claim 1.
  • a light barrier positioned in the beam path of a spray jet that can be emitted by the spray arm sends a signal to an evaluation unit, the signal having a signal curve that is dependent on a rotational movement of the spray arm, and the signal curve being evaluated by means of the evaluation unit for the purpose of monitoring the function of the spray arm.
  • a light barrier preferably an IR light barrier, serves as the sensor. This is positioned in the beam path of a spray jet that can be emitted by the spray arm. A spray jet emitted by the spray arm during operation therefore also crosses the detection area covered by the light barrier. During operation, the light barrier is cyclically interrupted by the spray jet emitted by the rotating spray arm.
  • the signal emitted by the light barrier has a signal profile that is dependent on a rotational movement of the spray arm. This is a function of the speed of rotation of the spray arm during operation. The time interval between two interruptions in the light barrier is directly dependent on the speed of rotation of the spray arm.
  • the recorded actual signal course is evaluated by means of an evaluation unit with a predeterminable reference signal course. If the signal curves match, this means that the spray arm is functioning properly. If, however, there is a discrepancy between the actual signal curve and the reference signal curve, this means that the spray arm is not functioning properly.
  • the procedure according to the invention is advantageous for two reasons in particular.
  • the functionality of the spray arm, which interacts with the dosing opening of the dosing unit, can be monitored. It is not only possible to detect whether the spray arm is moving as intended, it can also be determined whether washing solution is being dispensed via the spray arm as intended. In contrast to the DE 10 2014 205 266 A1 it is therefore also possible to detect the undesired operating state that only the spray nozzle of the spray arm that interacts with the metering opening is clogged. If only this nozzle were clogged, the spray arm would continue to rotate, but the dosing opening assigned to this spray nozzle would not be cleaned due to the nozzle clogging. This failure case can also be detected by carrying out the method according to the invention.
  • Another advantage is that no additional detection elements to be arranged on the spray arm are required to carry out the method according to the invention.
  • the light barrier provided on the dosing opening side is used to monitor the spray arm. This does not interact with an aid to be detected, but directly with the spray jet emitted by the spray arm.
  • the configuration on the machine side can also be used unchanged for carrying out the method according to the invention. Additional manufacturing costs are avoided in this respect and the process can also be carried out in a simple manner, since the washing program carried out in the intended use can be used in unchanged form for function monitoring.
  • the main function of the light barrier used in carrying out the method according to the invention is to detect cleaning agent trickling into the washing area. It is also provided that a spray arm directed onto the dosing opening is emitted in order to ensure that the dosing opening is always free of cleaning agent residues. In order to also ensure that the dosing opening is actually cleaned, the function of the spray arm is monitored by means of the implementation of the method according to the invention. In contrast to the prior art, the implementation of the method according to the invention enables not only a detection of the spray arm rotation, but also a detection of the washing solution dispensed by the spray arm, so that a possibly clogged spray nozzle can also be recognized.
  • the spray device arranged in the interior of the washing compartment of the dishwasher has a plurality of rotatably mounted spray arms.
  • the spray arm which interacts with the metering opening in the manner described above is typically the spray arm which is arranged at the bottom in the vertical direction. In the intended washing case, this spray arm is used to load items to be washed that are arranged in a lower basket.
  • All of the spray arms are connected to a water switch in a manner known per se, and depending on the position of the water switch, the corresponding spray arms are charged with washing liquor.
  • alternating rinsing usually takes place in which at least two spray arms are alternately supplied with washing solution by means of the water diverter.
  • the light barrier is used to monitor detergent dosing during a phase of a running wash program in which the lower spray arm, that is, the spray arm cooperating with the dosing opening, is not supplied with washing liquid. This ensures that the detergent dispensed can flow unhindered into the wash cabinet.
  • the evaluation unit compares the signal curve with a predeterminable reference signal curve and emits a display signal if they are not identical.
  • a display signal can be an acoustic and / or visual signal output to the user so that he can carry out a manual check of the spray arm.
  • provision can also be made for the dishwasher to be switched off automatically if they are not the same. In any case, it is ensured that the metering opening does not inadvertently become clogged, unnoticed by the user. In the worst case, such an addition could lead to a complete failure of the dosing unit and thus of the entire dishwasher, which is impossible thanks to the method according to the invention.
  • the invention also proposes a dishwasher which is characterized by a sensor unit which, by means of the light barrier, generates a signal with a signal curve dependent on a rotational movement of the spray arm, and which compares an actual signal curve with a predeterminable reference signal curve using an evaluation unit.
  • the dishwasher proposed by the invention has a sensor unit by means of which the function of the spray arm is monitored.
  • the sensor unit includes the light barrier formed on the dosing opening side, on the one hand, and an evaluation unit, on the other hand.
  • the light barrier generates a signal with a signal curve that is dependent on a rotational movement of the spray arm.
  • This signal course is evaluated by means of the evaluation unit, for which purpose the evaluation unit compares the recorded actual signal course with a predeterminable reference signal course. If a discrepancy is found between the signal profiles, the dishwasher is automatically switched off and / or an alarm signal is output to the user.
  • the dishwasher also has a dosing unit, preferably provided by the wash cabinet door, for storing pourable cleaning agent, in particular for a plurality of cleaning cycles.
  • the dosing unit has a discharge channel, which is connected to the dosing opening opening into the washing area, for introducing cleaning agent into the washing chamber, in particular in portions.
  • the discharge channel has the light barrier on the dosing opening side. In the manner already described above, this arrangement allows detection of the cleaning agent that has been introduced into the washing chamber via the metering opening during operation.
  • the metering opening is partially covered by a cover on the wash space side, leaving a metering gap.
  • This cover advantageously ensures that when the dishwasher is loaded with items to be washed, liquids, dirt, food residues and / or the like do not inadvertently fall into the mouth area of the dosing opening can, for example, by dripping or falling of items to be cleaned, with which the dishwasher is equipped by the user.
  • the cover covering the metering opening is designed in the manner of a hood or scoop which, in the closed position of the wash cabinet door, is designed to be open at the bottom and thus provides a metering gap.
  • a hood or scoop which, in the closed position of the wash cabinet door, is designed to be open at the bottom and thus provides a metering gap.
  • the design of such a hood has the advantage that the metering opening is closed on all sides except for the metering gap, so that unwanted introduction of dirt, liquids, food residues and / or the like into the metering opening is largely prevented.
  • the dosing gap left by the hood is aligned in such a way that it points downwards in the closed position of the wash cabinet door.
  • the dosing unit has a dosing device with a cleaning agent outlet and the discharge channel, the discharge channel fluidically connecting the cleaning agent outlet to the metering opening.
  • the metering device When used as intended, the metering device preferably holds a storage container which is used to store pourable cleaning agent for a plurality of cleaning cycles. In the case of dosing, a correspondingly portioned amount of cleaning agent is taken from the storage container, which leaves the dosing device via a cleaning agent outlet.
  • a discharge channel For the fluidic connection to the metering opening, a discharge channel is provided which opens into the metering opening. This channel is laid on the inside of the door, which results in a spatial decoupling of the dosing device on the one hand and the dosing opening on the other. Unintentional entry of liquid into the cleaning agent stored in the dispensing device's reservoir is effectively prevented.
  • the discharge channel has the light barrier or another, preferably optical, sensor on the dosing opening side.
  • This sensor is used to detect detergents which, in the event of a dispensing, enter the discharge channel via the dispensing opening duly leaves. In this way it can be detected in an advantageous manner whether or not cleaning agent actually gets into the washing area in the event of a detergent being dispensed by the dosing device. Furthermore, by detecting the detergent portions actually dispensed, conclusions can be drawn about the filling level of the storage container. In this respect, the sensing also serves to be able to indicate to the user at an early stage that the storage container is to be refilled with cleaning agent or to be exchanged for a fully filled storage container.
  • the sensor is preferably an IR light barrier. This is preferably arranged near the metering opening, where "near" in the sense of the invention means that the spray jet emitted by the spray nozzle cooperating with the metering opening during operation also ensures cleaning of the sensor. It is thus ensured in a synergetic manner that not only the dosing opening and the discharge channel opening into the dosing opening, but also the sensor provided for detecting the detergent release are subject to repeated cleaning, which advantageously increases operational reliability.
  • a spray arm has a large number of spray nozzles which are used to dispense wash liquor during operation.
  • the spray nozzles are aligned in such a way that the items to be cleaned are loaded with washing liquor.
  • One of these nozzles, which are already provided, is now used to effect cleaning, in particular of the metering opening, in the manner described above during operation.
  • the spray nozzle is preferably aligned with the metering opening in such a way that the spray jet emitted by the spray nozzle during operation hits the spray gap not covered by the hood when the spray arm is appropriately rotated.
  • the inside of the hood, the dosing opening, the discharge channel opening into the dosing opening and the sensor provided for detecting a detergent release are cleaned.
  • the discharge channel is provided by a pipe which is designed to be flexible.
  • This flexible configuration of the pipe ensures that the discharge channel can be decoupled from the dosing device in terms of flow technology, that is to say from the cleaning agent outlet provided by the dosing device, which helps prevent an unwanted one To be able to prevent the entry of liquid into the detergent stored in the storage container of the dosing device.
  • the pipe providing the discharge channel can, for example, be rotatable or pivotable due to its flexibility, which makes it possible to bring the pipe into fluidic connection with the cleaning agent outlet or to separate this fluidic connection.
  • the tube providing the discharge channel can also be designed as a squeeze tube, which is held in a squeezed position for a fluid-tight closure in the case of non-dosing.
  • the inventive design of the outlet area including hood with the arrangement of a sensor for detergent detection in connection with the specifically aligned spray arm nozzle can counteract contamination of the metering outlet and the sensor measuring section.
  • the hood provides optimized spill protection for the dosing or discharge channel, effectively holding back food and drink residues that could fall onto the inner door panel when the dishwasher is being loaded.
  • Fig. 1 shows a dishwasher 1 in a purely schematic representation.
  • this has a housing 2 which accommodates a washing container 3.
  • the washing compartment 3 in turn provides a washing area 4 for receiving items to be cleaned.
  • the washing compartment 3 has a loading opening 5. This can be closed in a fluid-tight manner by means of a washing compartment door 6, the washing compartment door 6 being rotatably pivoted about a horizontally extending pivot axis.
  • the dishwasher 1 has a spray device 8.
  • the spray device 8 includes an upper spray arm 9 and a lower spray arm 10, each of which is rotatably mounted and has two spray arm branches 11 and 12 or 13 and 14.
  • Fig. 2 an interior view of the wash cabinet door 6 can be seen.
  • the inside of the washroom door 6 has a combination device 15 known per se from the prior art, which on the one hand has a rinse aid supply 16 and on the other hand has a storage container 17 which is to be filled manually with detergent by the user for each cleaning cycle.
  • the dishwasher 1 also has a dosing unit 18, which is also accessible to the user via the inside 7 of the wash cabinet door 6.
  • the dosing unit 18 has a housing 20 which houses a dosing device 21.
  • the metering device 21 is accessible to the user via a loading opening provided by the housing 20.
  • the loading opening of the housing 20 is closed fluid-tight by means of a housing cover 22.
  • the dosing device 21 of the dosing unit 18 dispenses cleaning agent in portions, which then flows into the washing area 4 of the dishwasher 1.
  • a metering opening 23 is provided on the inside 7 of the wash cabinet door 6. This metering opening 23 is covered on the treatment room side with a cover in the form of a hood 24.
  • a pipe 27, which provides a discharge channel 19, is used to transfer cleaning agent from the metering device 21 to the metering opening 23.
  • the tube 27 serves to fluidically connect a cleaning agent outlet of the metering device 21 to the metering opening 23.
  • cleaning agent dispensed by the dosing device 21 can thus pass through the pipe 27 to the dosing opening 23 and then into the washing chamber 4.
  • the tube 27 is designed to be pivotable in the plane of the door. In the closed position, the tube 27 is not connected to the dosing device 21 in order to avoid an undesired entry of moisture into the dosing device 21.
  • the pipe 27 is to be pivoted in the plane of the door. This pivotability of the tube 27 is made possible by the fact that the tube 27 is designed as a flexible tube and consists, for example, of silicone or a comparable material.
  • one branch 13 of the lower spray arm 10 of the spray device 8 is equipped with a spray nozzle 25 which is aligned with the metering opening 23 in such a way that the spray jet 26 emitted by the spray nozzle 25 when the spray arm 10 is turned into one of the hood 24 meets uncovered metering gap 30.
  • the discharge channel 19 of the pipe 27, which opens into the metering opening 23, and the metering opening 23 are charged with rinsing liquor, which effects a corresponding cleaning. Any cleaning agent residues are removed in this way and flushed out into the washing area 4.
  • it is avoided that encrustations, deposits and / or similar soiling as well as any cleaning agent residues can accumulate and lead to a narrowing of the discharge channel 19 and / or the metering opening 23.
  • the dishwasher 1 has an IR light barrier 28 in the outlet area of the discharge channel 19, which provides a light beam 29 that traverses the area of the dosing opening 23.
  • This IR light barrier 28 can advantageously be used to detect whether the detergent portion dispensed by the dispensing device 21 has actually reached the washing area 4. It can be monitored whether in the case of Detergent delivery an arrival of detergent in the wash cabinet has actually taken place. Should such a detection detect that no cleaning agent has flowed into the washing area despite the cleaning agent being dispensed, this can be indicated to the user of the dishwasher 1 and / or the started washing program is interrupted. The detection of the cleaning agent introduced into the washing chamber 4 can also be used to draw conclusions about the amount of cleaning agent still stored in the dosing device 21. This can also be communicated to the user of the dishwasher 1, for example via a consumption display.
  • the arrangement of the light barrier 28 and the alignment of the spray nozzle 25 are matched to one another in such a way that, in the event of operation, the wash liquor also reaches the transmitter and receiver units of the IR light barrier 28, so that the measurement section is also cleaned.
  • the metering opening 23 is covered by the hood 24 in the manner already described. With the exception of the metering gap 30, the hood 24 completely surrounds the metering opening 23, so that the greatest possible penetration protection is provided.
  • the metering opening 23 is arranged within an area 32 of the wash cabinet door 6, which is offset downwards compared to the rest of the inside 7, and therefore represents a depression compared to the rest of the inside 7.
  • This recess is used to safely collect and accommodate any liquids that may drip off the items to be cleaned. This ensures that any dripping liquids cannot overflow to the right or left of the wash cabinet door.
  • the metering opening 23 is surrounded by a frame 34, which, with reference to the plane of the drawing, can be seen in FIG Fig. 2 the lower section represents a barrier. This barrier serves as overflow protection so that liquids that may have been taken up by the area 32 cannot pass unhindered through the metering opening 23 into the discharge channel 19.
  • the frame 34 and the hood 24 are preferably designed as a one-piece component.
  • the spray arm 10 passes the dosing gap 30 with its spray nozzle 25 once every 360 ° and consequently releases washing solution into the dosing gap 30. This has the consequence that the light beam 29 of the light barrier 28 positioned there is interrupted.
  • the light barrier 28 positioned in the beam path of the spray jet 26 emitted by the spray arm 10 emits a signal to an evaluation unit.
  • the signal has a signal profile that is dependent on the rotational movement of the spray arm 10.
  • An evaluation unit can then be used to evaluate the signal curve, for which purpose the detected actual signal curve is compared with a predeterminable reference signal curve.
  • Fig. 5 shows a typical signal curve in a diagram.
  • the voltage profile of the light barrier 28 is shown over time. It can be seen that the voltage deflects at regular intervals, in the present example every three seconds. Each deflection is therefore synonymous with an interruption of the light barrier 28 by the wash liquor jet entering through the dosing opening 30. If the freedom of rotation of the spray arm 10 is blocked and / or the nozzle 25 is clogged, there is no interruption of the light beam 29 and thus the typical signal curve as shown in FIG Fig. 5 is shown. The absence of a signal curve as shown in Fig. 5 is therefore synonymous with the fact that the proper functionality of the spray arm 10 is no longer guaranteed.
  • alternating washing usually takes place, in which at least two spray arms are alternately supplied with washing solution by means of a water switch.
  • the dosing by means of the dosing unit and its monitoring by means of the light barrier 28 is carried out in a phase of the washing program in which the lower spray arm 10 is not supplied with washing liquid. This ensures that the detergent dispensed into the wash cabinet is unhindered can flow in.
  • the functionality of the lower spray arm 10 is also sensed by means of the light barrier 28, specifically in all phases of a washing program in which the lower spray arm 10 is supplied with washing solution.
