Definitions
- the invention relates to a method for adjusting and correcting a turbidity sensor in a program-controlled water-conducting household appliance, in particular in a dishwasher, to changing conditions at the measuring location, while the washing program is running Calibration or reference values for sensor adjustment and for correction of the turbidity sensor be determined during turbidity measurements of the rinsing liquid.
- the preferred turbidity sensors used in washing machines or dishwashers are constructed according to the light barrier principle and consist of a transparent plastic tube, through which the medium to be measured (rinsing water) flows.
- a transparent plastic tube through which the medium to be measured (rinsing water) flows.
- an optical measuring section consisting of an optical transmitter (Light-emitting diode, lamp or the like.) And an optical receiver (photo transistor or the like.) built up.
- the attenuation of the light caused by the turbidity is evaluated within the measuring section to control the washing program depending on the measurement result, sh. for example US 3,888,269.
- the invention thus poses the problem of a calibration method for a in a water-bearing Household appliance used to create turbidity sensor, with which to Reliable correction values for the purpose of achieving optimal rinsing or cleaning results for the sensor in turbidity measurements even under changing conditions on Have the measurement location achieved.
- the best calibration measurement value in each case the rinse water turbidity is the lowest, from a series of measurements containing several wash program runs is selected for determining the reference value, with several best selected calibration measurement values from several separate rinsing program runs for the final formation of the reference value averaged, it is ensured that the optimal reference value for turbidity correction is always used is used.
- the multiple measurement preceding the value determination provides sure that at least one of the best calibration measurement values from the measurement value series is clear Fresh water is determined.
- the invention is based on an electronically program-controlled dishwasher (1) as a water-bearing household appliance, its manual or automatic selectable wash programs (SP) each program section, such as pre-wash (V), cleaning (R), intermediate rinsing (ZW), rinsing (K) and drying (T) according to FIG. 2, with each after the degree of soiling of the loaded dishes or in circulation the pre-rinse and / or intermediate rinse cycles located in or additionally can be controlled.
- the last program section rinse aid (K) closes Regularly the drying section (T) starts, while continuing at the start of the washing program (SP) generally before pre-rinsing (V) the device's own softener after regeneration is rinsed with clear fresh water (pumping step A).
- washing in the Saline in the softener for regeneration is generally done after rinsing (K), the regeneration continues in the Drying (T) program section.
- Such dishwashers essentially have components and accessories, as shown in FIG. 1 the device shown is shown in simplified form, the sake of clarity concrete training of the program control (P) of the dishwasher (1), however, not is shown in more detail.
- the (1) designated and schematically shown front-loading household dishwasher 1 has a rinsing tank (2) and several spray arms (3, 4, 5), which over and between crockery baskets (6, 7) and a separate cutlery basket (8) in different washing levels are arranged in the washing container (2).
- the spray arms (3, 4, 5) are one of the circulating rinsing liquid (13) via assigned feed lines (11, 12) upstream circulation pump (9) fed, the rinsing liquid in the rinsing mode constantly is guided over a filter screen combination (10), which consists of a in the bottom of the washing compartment arranged fine sieve and consists of a coarse sieve and a fine sieve. There will be Filtered leftovers from the rinsing liquid (13).
- the cutlery basket (8) is a cutlery drawer trained and in a separate from the crockery baskets (6, 7) washing level the two separate crockery baskets (6, 7) lying one above the other in the washing compartment (2) arranged its own spray arm (5).
- the amount of rinsing liquid supplied is largely dependent on the amount of depending on cleaning dishes.
- the dishwasher (1) has an optical sensor in the form of a known sensor Turbidity sensor (15), which is connected to the program control (P) to predetermined At times in the aforementioned program sections the cloudiness of the Detects rinsing liquid and a measurement signal corresponding to the determined degree of contamination delivers which due to component and / or Light transmission tolerances or specimen scatter of the sensors with a stored one Calibration or reference value (RW) must be corrected.
- the turbidity sensor (15) or its measuring location is, for example, in the collecting pot of the dishwasher placed below the filter screen combination (10).
- the turbidity sensor (15) used works on the light barrier principle and consists of a transparent plastic tube through which the medium to be measured (rinsing water) flows. At right angles to the plastic tube there is an optical measuring section an optical transmitter (light-emitting diode, lamp or the like) and an optical receiver (Photo transistor or the like.) Built. The one caused by the turbidity is evaluated Attenuation of the light within the measuring section.
- the construction of the turbidity sensor (15) is on known and therefore not shown in detail. Turbidity sensors point to each other due to the component tolerances, the alignment of the optical components and the Tolerances in the translucency of the plastic on very strong scatter. Additional Scattering results from the component tolerances of the external wiring of the Sensor. In addition, deposits (e.g. lime) and / or damage to the Pipe surface within the measuring section as well as the aging of the optical components falsify the measurement results.
- a first calibration value measurement (KWM1) is carried out at the start of the program, preferably in Pumping-out step (A) when rinsing out the softener, the second measurement in the final rinse cycle (K) the rinse aid dosage at time (t2) and the third calibration value measurement (KWM3) at the end of the program section drying (T) at time (t3).
- the three Calibration value measurements (KWM1 to KWM3) result in corresponding calibration measurement values (KW1 to KW3).
- the calibration measured values (KW) from several wash programs (SP) are stored in a first one Storage table (ST1) according to FIG. 3 is saved and the measurement values obtained are used the best calibration measured value (KWb) selected and separately in a second memory table (ST2) saved. Then the first memory table (ST1) is deleted again and it calibration values (KW) in subsequent washing programs as described above (SP) recorded and stored in the first memory, whereupon the first memory table is filled up (ST1) again selected the best value (KWb) and into the second memory table (ST2) is written, etc. As soon as the second memory table (ST2) with the best calibration measurements (KWb) is written in full, by averaging the selected best values for the turbidity value corrections required calibration or reference value (RW) determined. The in Rinsing process of subsequent rinsing programs queried at certain times Turbidity values (TW) are then compared with the determined calibration or reference value (RW) corrected.
- TW Turbidity values
- the calibration value measurement is described in more detail below, assuming that in a washing program (SP) at different times (t; t ') three calibration values (KW) as well as three turbidity values (TW) are queried.
- the three calibration value measurements are used (KWM1-1 to KWM3-1) calibration measurement values obtained in the first washing program (SP1) (KW1-1 to KW3-1) as well as those from the following second washing program (SP2) determined calibration measurement values (KW1-2 to KW3-2) in the first memory table (ST1) of the rewritable, non-volatile memory (EEPROM) of the program control (P) stored separately, with each determined calibration measurement value (KW1-1 to KW3-2) at the measurement location adjusting component and / or light transmission tolerances are taken into account.
- the mean value is calculated, which is the new reference value (RW1) forms and replaces the factory-set reference value (RW0).
- the memory table (ST2) is then deleted and prepared for a new valuation.
- the turbidity measurements (TW) subsequent washing programs are new with the correct the determined reference value (RW1), etc.
- the optical transmitter LED or the like.
- the optical transmitter Of the turbidity sensor (15) on an adjustable Constant current source (IK), Fig. 4, operated.
- IK constant current source
- the Light output of the optical transmitter within predetermined tolerance limits of one Control computer (SR) of the program control (P) by means of a control signal (manipulated variable y) to be influenced.
- SR Control computer
- y control signal
- the turbidity sensor coming voltage signal (measurement signal x) the control computer (SR).
- (z) it will Designated measuring medium by damping the optical path of the turbidity sensor (15) acts on the control circuit shown in the block diagram according to FIG. 4.
- the light output of the optical transmitter is selected so that a clear operating point (Y 0 ; X 0 ) of the optical receiver (photo transistor or the like) of the turbidity sensor (15 ) sets.
- an additional power reserve to increase of the transmitted light output, so that the selected working point of the optical receiver can be used.
- the point in time when there is clear water in the running wash program (SP) at the measuring location cannot be determined with absolute certainty, as mentioned at the beginning. But yes the times (t1 to t3) can be determined with a high probability clear rinsing liquid (13) is located at the measuring point of the turbidity sensor (15). Therefore be several calibration value measurements (KWM), three measurements in the exemplary embodiment, carried out.
- the best calibration measurement value (KWb) is identified by the smallest diode current value that is used to set a defined phototransistor voltage (am Working resistance) is necessary.
- the reference value (RW) calculated by value averaging represents the diode current to be set Turbidity sensor (15), which is then used for turbidity measurement. decreases the luminosity of the transmitter diode of the Turbidity sensor (15) with the service life, this is due to the continuous increase of the diode current compensated.
- the light output of the optical transmitter of the turbidity sensor is thus varied within predetermined tolerance limits that can be derived from component and / or light transmission tolerances in order to achieve the defined operating point.
- the control signal X is readjusted until the defined operating point (Y 0 ; X 0 ) is set on the transmission characteristic of the entire measuring section. The cheapest is selected from “n” working points. In each case "m" favorable working points (measured calibration values) are averaged and result in the reference value for correcting the turbidity measurement values.
- the calibration value measurement must be carried out before the first rinse cycle (i.e. before the start of the program).
