Definitions

  • the invention relates to a method for the metered supply of rinse aid during rinsing in the final rinse liquid (rinsing liquor) in the washing of a program-controlled dishwasher, wherein the rinse aid concentration of the final rinse liquid is monitored by means of an optical sensor.
  • the program for washing a program-controlled dishwasher comprises a plurality of cleaning and rinsing operations, which are completed with a rinsing process.
  • the cleaned dishes located in the washing container are supplied with a rinse aid provided with a rinse aid.
  • the dosage of the rinse aid is often made by the customer, but the set amount is only a rough value. On the one hand, this can lead to overdoses and to unnecessarily high consumption of rinse aid. On the other hand, insufficient dosing often does not achieve the desired rinse effect.
  • manual dosing of the rinse aid can not take into account the quality of the rinse aid used.
  • combination preparations are designed so that initially only the cleaner and the softener dissolve and the rinse aid which is encapsulated in the combination preparation, e.g. is present in the form of a wax-coated bead, dissolves only dependent on temperature and / or pH during rinsing.
  • the rinse aid is dissolved before the actual rinse.
  • a defined rinsing liquid volume is supplied to the rinsing container. This can be fixed from the outset or be set variably depending on various parameters.
  • the essential factor in this case is the concentration of the rinse aid actually present in the rinsing liquid, since this has an immediate effect on the rinse aid result and thus on the drying result of the ware.
  • the rinsing liquid is supplied as low as possible, optionally as a function of the degree of turbidity of the rinsing liquid. If, on the other hand, the concentration of the rinse aid at the beginning of the rinsing program section is above average or sufficiently high, then the rinse aid concentration can be adjusted to a predetermined concentration by supplying a defined rinse liquid volume.
  • the beats DE 100 34 546 A1 the use of a radar sensor to determine the droplet size and shape or the state data of a wetted with the washing liquid test body to make statements about the state of the washing liquid, for example, their content of detergent.
  • the object of the present invention is to improve a method for the metered supply of rinse aid during rinsing in the final rinse liquid in the rinse tank of a program-controlled dishwasher so that underdosing of rinse aid is prevented in a simple manner in order to achieve an optimal drying result. Furthermore, a device for checking the rinse aid concentration in the rinsing liquid of a program-controlled water-conducting domestic appliance should be specified.
  • the wetting of the optical sensor with the final rinse liquid is used as a criterion for the metered supply of rinse aid.
  • the determination of the wetting as a criterion for the concentration of rinse aid in the rinse aid liquid means a check of the run-off behavior of the final rinse liquid from the sensor. In particular, this can be a check of the droplet size and droplet shape of the sensor to obtain a statement about the state of the final rinse liquid.
  • the concentration of rinse aid manifests itself in a change in the surface tension of the final rinse liquid.
  • the resulting flow behavior can be detected by the optical sensor and allows a conclusion on the rinse aid concentration in the final rinse liquid.
  • the rinse aid concentration causes the rinse aid action, so that the rinse aid concentration is also detected by the rinse aid concentration.
  • rinse aid from a rinse aid supply can be metered into the rinse tank until the required concentration of rinse aid has been reached.
  • the device for checking the rinse aid concentration in the rinsing liquid of a program-controlled, water-conducting household appliance has a sensor with at least one transmitting element which emits an optical signal and at least one receiving element which receives the optical signal emitted by the transmitting element, and a computing unit.
  • the arithmetic unit is set up to determine the wetting of the sensor with rinse-aid liquid and from it the concentration of rinse-aid in the rinse-aid liquid from the energy level emitted by the transmitting element and received by the receiving element.
  • the rinse aid concentration causes the rinse aid action, so that the rinse aid concentration is also detected by the rinse aid concentration.
  • the device according to the invention for checking the rinse aid concentration is preferably installed in a water-conducting device, in particular a dishwasher, wherein the device can be arranged on the side of the door or a wall of the washing compartment associated with the washing compartment.
  • the device for checking the rinse aid concentration can also be arranged on the ceiling or the bottom of the washing compartment.
  • the senor has a light-transmissive element into which the transmitting element couples the optical signal and the receiving element receives the optical signal coupled out of the light-transmissive element.
  • the concentration of the rinse aid in the final rinse liquid the wetting of this light-transmissive element of the sensor with rinse aid is then determined. In this case, the flow behavior on the light-transmissive element is detected by the transmitting and the receiving element in a simple manner.
  • the change in the rinse aid concentration in the final rinse liquid is expediently measured by the sensor with the transmitting element emitted by the optical signals and the receiving element receiving the optical signals, wherein a light beam is coupled into the light-transmissive element from the transmitting element of the sensor and from the light-transmitting element emerging light beam is measured by the receiving element of the sensor.
  • the term light beam is generally understood as an electromagnetic wave and not limited to specific wavelengths.
  • Suitable sensors which are proposed there for the detection of limescale, are for example in the DE 198 25 981 A1 as well as the DE 102 08 214 A1 known. However, the evaluation of the signals supplied by the sensor takes place at a different time than in the method according to the invention. Any limescale that may occur can only be detected at the onset of the drying process. However, the sensor principle used in these sensors can be applied in an adapted manner in the invention for detecting the wetting of the sensor.
  • the translucent element as in the DE 102 08 214 A1 described, having two end faces and is formed such that each of the optical signal emitting and the optical signal receiving element immediately connect to the end surfaces of the translucent element, so that the end surfaces are always free of a coating.
  • the light emitted from the optical signal emitting element e.g. Infrared light enters the transmissive element and, due to the reflection taking place in the transparent element, is reflected at the interface between the transparent element and the surrounding atmosphere, such that the light beam or light beam is substantially radiated with scattering losses through the transparent element and finally through the second end surface assigned to the receiving element emerges and into which the receiving element enters. Due to the total reflection taking place in the translucent element, a brightness value is required which corresponds to a specific energy value. An energy difference amount between the optical signal-emitting element and the optical signal-receiving element is due to a certain radiation power of the transparent element and is taken into account in the processing of the signal value.
  • Infrared light enters the transmissive element and, due to the reflection taking place in the transparent element, is reflected at the interface between the transparent element and the surrounding atmosphere, such that the light beam or light beam is substantially radiated with scattering losses through the transparent element and finally through the second end surface assigned to the receiving element emerges
  • the refractive index between the light-transmissive element and the immediately following deposition layer is changed at these regions so that the number of total reflections at the boundary layer of the translucent element decreases. If a light beam or a light beam impinges on the boundary surface of the light-transmissive element at a certain angle and this area of the light-transmitting element is covered with rinse liquid, some of the light beam will exit the light-transmissive element and will not be absorbed into the light-transmitting element translucent element reflects. Since the receiving element measures the energy intensity of the exiting light from the translucent element, the receiving light intensity is associated with a corresponding wetting on the translucent element.
  • rinse aid takes place, depending on the information determined.
  • determining the wetting of the optical sensor it is preferred not to determine merely an instantaneous value, but rather to determine the wetting of the light-transmitting element with the rinsing liquid as a function of time in order to obtain an accurate statement can be obtained via the rinse aid concentration in the rinse aid liquid and to be able to take into account the runoff behavior of the sensor or the light-transmitting element.
  • a circulation of the final rinse liquid with subsequent renewed measurement of the concentration of the rinse aid in the final rinse liquid takes place.
  • the circulation ensures that added rinse aid can mix with the final rinse liquid. The falsification of a measurement result by possibly occurring concentration ranges of rinse aid in the final rinse liquid can be avoided.
  • the determination of the rinse aid concentration in the final rinse liquid is preferably carried out iteratively until a predetermined value of rinse aid concentration in the final rinse liquid is reached.
  • the rinsing process is adjusted as a function of the concentration of rinse aid in the final rinse liquid in its course. In other words, this means that a dosage of rinse aid, a circulation and a measurement of the rinse aid concentration takes place until the desired rinse aid concentration in the final rinse liquid is reached. Only then does the actual rinse aid program continue.
  • the dishwasher takes in a washing up the dishes to be cleaned.
  • a program control takes over the course of the cleaning and rinsing operations with the supply, heating and suction of the cleaning and rinsing liquid in a known manner and is therefore not described in detail.
  • the Spülbeggiter At least one optical sensor is assigned, which monitors the rinse aid liquid to the concentration of rinse aid and outputs a corresponding actual value to a computing unit of the program control. As long as the actual value does not reach a setpoint stored in the arithmetic unit, the arithmetic unit sends a signal to a dosing device which supplies a rinse aid continuously or at intervals into the rinse aid liquid. If the actual value detected by the optical sensor corresponds to the predetermined desired value, then no supply of rinse aid takes place.
  • step 10 the start of the rinse program begins.
  • rinse aid is metered into the rinse aid liquid of the dishwasher (step 12).
  • the dosage of the rinse aid can be effected by the aforementioned "3-in-1" combination preparations or in a known manner by a Klar Kunststoff Kunststoff- reservoir.
  • the rinse aid liquid then circulates in a known manner (step 14).
  • the optical sensor present in the washing compartment is also washed around by the rinse aid liquid. The optical sensor is arranged in the washing compartment so that the rinse aid liquid can flow away from the optical sensor again. During this outflow, the wetting of the optical sensor with the rinse aid liquid is detected (step 16).
  • the translucent element is arranged in a region of the washing compartment, which allows a rinsing with the final rinse liquid.
  • the translucent element could be arranged in a chamber-like region which has at least one opening which opens into the interior of the washing container and has a valve which is suitable for emptying the chamber-like region again.
  • the shape of the translucent element is in principle arbitrary. As appropriate, a rod-shaped or helical-shaped shape, which allows a longer light path for the measurement, has been found. It is also conceivable to arrange several translucent elements between transmitting and receiving element, since then the light spectrum can be selected wider. So could the preferred infrared range be varied in the individual translucent elements and the associated optical signals emitting / receiving elements.
  • the physical phenomenon on which the device according to the invention is based is based on a comparison of the light level coupled into the light-transmitting element by the transmitting element with an energy level which is detected by the receiving element during coupling out of the light-transmissive element. If the translucent element has no wetting, substantially all the light beams which are coupled into the translucent element from the transmitting element are reflected due to the total reflection between the translucent element and the surrounding atmosphere until they reach the receiving element and do not leave the translucent element. Due to this, the energy level coupled into the light-transmissive element essentially corresponds to the energy level coupled out of the light-transmissive element.
  • the light-transmitting element is washed around by rinse liquid, a certain energy level is coupled in when the transparent element is irradiated on the side of the transmission element and a different energy level is received on the side of the receiver element.
  • the energy level detected by the receiving element is substantially lower than the energy level coupled in by the transmitting element.
  • Rinse liquid provided with an optimum level of rinse aid will only cause wetting on the sensor or the light-transmissive element for a very short time.
  • rinse aid liquid having too low a dosage of rinse aid will adhere to the sensor or light-transmissive element for an extended time before it expires. This difference in time is used to measure the wetting of the sensor or the light-transmissive element. The measurement therefore takes place either continuously over a certain period of time in order to detect the run-off behavior of the final-rinse liquid from the sensor or the light-transmitting element. Alternatively, a variety of measurements can be made in short, consecutive time intervals.
  • the comparison of the energy levels over time allows a statement about the wetting of the sensor or the light-transmissive element and thus also about the level of rinse aid in the final rinse liquid.
  • the rating of Measured values can be carried out with (threshold) values stored in the arithmetic unit or else on the basis of a calculation.
  • the evaluation of the wetting takes place in the flowchart in the process step identified by the reference numeral 18. If the wetting is small (reference numeral 20), the actual rinsing process and subsequent drying process can begin with a further circulation in accordance with method step 28. If the wetting was large (reference 22), then in step 24 a metered addition of rinse aid, e.g. from a rinse aid reservoir. Before the actual rinsing process (reference numeral 28) is initiated, a new step of measuring and checking the rinse aid concentration in the final rinse liquid takes place (reference 26). This in turn comprises the circulation in accordance with method step 14, the measurement of the wetting according to method step 16 and the evaluation of the wetting according to step 18 in the manner described above.
  • rinse aid e.g. from a rinse aid reservoir
  • the automatic supply of the ideal amount of rinse aid limits the amount of rinse aid to the required level and ultimately leads to a saving of the same. In addition, an ideal drying result for the consumer is achieved.
