  • the liquid turbidity is measured in operating phases in which the laundry loader stops and does not introduce any air bubbles into the wash, which will measure their turbidity could influence.
  • the turbidity measurement is used to control the flushing process carried out on a moving Wäschebeweger to use the registered Bubbles determine the concentration of detergent in the rinse and the Rinse process when falling below a certain detergent concentration to end can.
  • liquid-conducting household appliances in certain Operating phases necessary to pump or drain liquid.
  • This can be, for example used in a washing machine spent liquor or rinse liquid, which after a Wash or rinse must be removed from the household appliance.
  • This is in the Usually a pump used.
  • This can be done, for example, that already all liquid was pumped or drained, or that the liquid is not sufficient Quantity runs into the inlet of the pump.
  • the latter can especially when spinning of laundry happen when increasingly less flushing liquid is ejected from the laundry which, however, must be pumped out.
  • spinning can prove to be another Problem arise that by the rotational movement of a laundry drum in a tub Fluid entrained, thrown against the inner wall of the tub and there forms a water ring that does not run or bad and therefore bad can be pumped out.
  • the present invention is based on the object, a method and a household appliance To provide a turbidity sensor of the type mentioned, with which at low Effort the control of Abpump- or drainage of the liquid improved and in particular the suction of air can be avoided by a pump.
  • this object is achieved by a method according to the characterizing part of claim 1 and by a turbidity sensor according to the characterizing part of claim 7 and a household appliance according to the characterizing part of claim 9 solved.
  • the output signal of a turbidity sensor which is used to control a washing and / or rinsing is provided anyway, based on certain components evaluated and thus monitored in particular the liquid level. Based on this evaluation the Abpump- or discharge process can be controlled accordingly.
  • the effort required for this is limited to the implementation of the corresponding Evaluation algorithms in the control device.
  • program-controlled household appliances usually with a microprocessor or microcontroller with associated program memory
  • the expansion of the control program is particularly simple possible. It is even possible to retrofit the invention in control devices, where the control program can be changed. This is for example through Change the control program in an EEPROM memory or a battery-backed one RAM memory or by replacing the memory chip possible, the control program contains. Since no additional components are required, so can the invention realize particularly cost-effective.
  • the evaluation of the output signal of the turbidity sensor can be done in different ways respectively.
  • the components of the output signal used for the evaluation are certain characteristics of the output signal or its course. The characteristics could for example be the DC component and generally spectral components.
  • the parts of the output signal can be determined in the time domain or in the frequency domain. It is also conceivable to use the z or Laplace transformation for evaluation.
  • the output signal may be at least one stored reference value or a stored range of reference values.
  • Various media reference values are stored that have a common value or range indicate the turbidity of the respective medium.
  • such Values or ranges for the media clear water, unused wash liquor, used up Wash liquor and air are stored.
  • Air is the distinction between Air and in general all operating fluids for pump down or drain control Of particular interest, so that ranges of reference values also alone for These two types of media can be stored.
  • the reference values may vary Be stored in the home appliance or determined by the household appliance itself and be stored, the household appliance, these reference values even after a certain Time can update, for example, errors due to aging or pollution to avoid the turbidity sensor.
  • the reference values can be determined at times in which it can be safely assumed that a particular Medium is in the measuring range of the turbidity sensor. For example, the Reference value or the reference value range for air before admitting Liquid and the spent liquor at the end of a wash cycle are determined.
  • the evaluation can also be based on the time course of the output signal. As long as a certain medium is in the measuring range of the turbidity sensor or flows through it, the output signal is usually little and only with change with limited speed. If necessary, changes in turbidity occur Within a medium usually stir from a poor mixing the liquid. However, these changes are usually not very pronounced and especially not be abrupt. The differences of the output signal for two different media will usually be much more pronounced. In addition, that mainly the distinction between the media air and generally liquids should be made possible and the turbidity difference in these media usually special will be high.
  • the output signal can be examined for jumps that are due to pass through a sharp border between media with different haze through the Point the measuring range of the turbidity sensor.
  • the output signal waveform on kinks or other changes to investigate or to evaluate its derivatives according to the time. If it is for example, by foaming or mixing of the media in the border area sets a temporally continuous transition between their turbidity values is under the requirement of different turbidity for the media of the output signal course nevertheless, starting from the turbidity value of the first medium, rise first and then stagnate at the turbidity value for the second medium, resulting in the Switch between two media can be closed.
  • the pumping or draining depending on alternating signal components be controlled of the output signal. This is especially possible in cases where in the case of a medium, permanent short-term changes in turbidity as it flows through through the measuring range of the turbidity sensor due to entrained inclusions occur. These can be dirt particles, especially in spent wash liquor or air bubbles, which are registered by a movement of liquid in this may have been. Such inclusions can be due to different light transmission and / or by the scattering of the light used for turbidity measurement a change effect the output signal.
  • the Output signal to DC component have additional alternating signal components, wherein the contained therein frequencies of the concentration of these inclusions and the speed with which they pass through the measuring range of the turbidity sensor from the medium be carried through. It can be a kind of superimposed noise in this way result.
  • Such alternating signal components can be amplified by the measuring range the turbidity sensor used in the flow direction of the liquid a small extent possesses, so that even small inclusions affect the turbidity measurement strong can.
  • the aforementioned methods for evaluating the output signal can be with each other combine to improve the evaluation or make it safer. Both Procedures in which the time course is evaluated, the output signal can also be processed by analog circuits before, for example, from a microprocessor or controller is evaluated with analog / digital converter. These can High passes for separating a DC component or differentiating elements for better detection of jumps or generally changes in the waveform.
  • the Liquid from the household appliance can be controlled in various ways. For example it can be determined whether the measuring range of the turbidity sensor is filled with liquid, and depending on this, the draining or draining operation can be controlled. In particular, can the draining or pumping are stopped when the measuring range is no longer liquid is satisfied, indicating a sinking of the liquid level below the installation location of the turbidity sensor suggesting.
  • Such state-dependent control in the cases in which no liquid is available for pumping or draining, an unnecessary Extend this process and the associated loss of time and energy avoided. Furthermore, it is possible in this way, the liquid to a well-defined Stand to empty, so that optimal conditions for the program flow of the household appliance can be produced.
  • the pumping or discharge process can only one certain period of time after the determination is concluded that the measuring range of the turbidity sensor is no longer satisfied by washing or rinsing liquid. Because of the turbidity sensor signal can only be determined that the liquid level below the installation of the turbidity sensor can be reduced in this way by extending the Abpump- or drain also a final liquid level below the installation height of the Turbidity sensor is to be achieved with increased accuracy. This period of time may in particular depend on the volume of liquid between the installation location of the turbidity sensor, the level of liquid desired at the end of the pump down or drain operation and the speed at which the fluid is pumped or drained becomes. These values may be stored in the controller.
  • the measuring range of a turbidity sensor for carrying out the method according to the invention can advantageously be provided with a surface that the expiration of the Promotes washing or rinsing liquid.
  • a liquid repellent Coating be used.
  • Conceivable are also narrow channels, by capillary action move the liquid out of the measuring range. In this way it is avoided that after passage of liquid, the light in the turbidity sensor due to broken drops are broken and a high haze value is measured, though There is already air in the measuring range. Otherwise, it may be due to stuck Drops are not found that no more liquid in the measuring range the turbidity sensor is located and the pumping or draining no longer correct to be controlled.
  • Fig. 1 shows the lower part of a tub 1 of a liquid 7 leading Household appliance, which in the present case is a washing machine. Down to the tub 1 is connected to a drain hose 2 for discharging the liquid 7, for example Washing liquor or rinse liquid can be, according to the individual Waschwhosetician Rinses must be derived.
  • the drain hose 2 leads to a Drain pump 3 for pumping the no longer required liquid 7 through a drain pipe 4, to which a line, not shown, connects to a waste water connection.
  • the drain hose 2 has a straight portion above a bellows, with he is connected to the tub 1 and made of transparent material. On both sides of this transparent portion are a light transmitter 5 and a light receiver 6 arranged opposite to each other. The emitted from the light transmitter 5 Light shines through the transparent portion of the drain hose 2 and in this Section located medium and incident on the light receiver 6. Light transmitter 5 and light receiver 6 together form a turbidity sensor 5, 6, with a not shown electronic control device is connected. The controller evaluates the output signal of the light receiver 6 and determines the light transmittance or a turbidity value for the medium in the transparent portion of the drainpipe 2. The interior of this transparent portion thus forms the measuring range of the turbidity sensor 5, 6.
  • the medium may, depending on the operating phase of the washing machine, for example Be air, wash, rinse or clear water.
  • Fig. 1 the above-described Arrangement shown after the Abpumpvorgang at the end of a pumpdown.
  • the turbidity profile measured over time t measured with the turbidity sensor 5, 6 during a pump-down operation after a wash cycle is shown schematically in FIG. 2 by the curve A.
  • the curve A At the beginning of the Abpumpvorgangs flows through the measuring range of the turbidity sensor 5, 6 wash liquor 7, which is loaded with detergent residues and dirt particles and therefore has a high turbidity T 1 .
  • T 1 At the time t 0 , all the wash liquor 7 has passed through the measuring range of the turbidity sensor 5, 6.
  • the turbidity value measured for air can depend very greatly on the design of the turbidity sensor 5, 6 used.
  • the measured turbidity value can depend strongly on the arrangement of the windows.
  • the design of the turbidity sensor 5, 6 can thus influence the turbidity value measured for air.
  • the control device of the washing machine monitors the waveform and compares it with the upper or lower limit of a stored reference range for the turbidity value of wash liquor 7. As long as the measured turbidity value is within this range, it is assumed that wash liquor 7 is still in the tub 1 and the pumping process continues. If, at the time t 0, the turbidity value leaves the reference range, the control device carries out the comparison on the basis of the reference range for the turbidity, since according to the program flow after pumping the wash liquor 7 air would have to flow into the turbidity sensor 5, 6.
  • the waveform B is shown under unfavorable conditions of measurement, in contrast to the course of FIG. 2, the measured turbidity at time t 0 does not fall to nearly zero, but only up to an overlying value T 2 .
  • the reason for this may be aging of the turbidity sensor 5, 6, in which the original light transmission of the components has decreased, contamination due to detergent residues or calcification. As a result, there is a danger that the measured turbidity value will no longer fall in the reference range of the turbidity, although air is in the measuring range of the turbidity sensor 5, 6.
  • the controller may use the occurrence of the jump from T 1 to T 2 , which also leads to a long-lasting change in the measured turbidity, for determining whether all the wash liquor 7 has passed through the turbidity sensor 5, 6.
  • the control device can use an alternating signal component D of the turbidity profile, which is shown in FIG. 5.
  • the alternating signal component D may have been obtained by connecting a high-pass filter and occurs during the pumping process as a kind of noise, which originates from the dirt particles and air bubbles contained in the wash liquor 7 and carried by the measuring range of the turbidity sensor 5, 6.
  • the control device can determine whether all the wash liquor 7 has run past the turbidity sensor 5, 6. Since in this type of evaluation the DC component is disregarded, it is insensitive to all influences which have an effect on the measurement of the absolute turbidity value, such as, for example, drops of liquid in the measuring range or aging or contamination of the sensor 5, 6.
  • FIG. 4 shows the signal curve C during pumping during a spin cycle. Since only little liquid 7 is ejected, especially towards the end, only small amounts of liquid still flow through the measuring range of the turbidity sensor 5, 6. In addition, this can be done completely irregularly. For this case, t 0 indicates the time from which the outflowing liquid quantity can no longer completely fill the measuring range of the turbidity sensor 5, 6, but only small amounts of the liquid 7 flow along the wall in individual rivulets. These cause irregular jumps of different duration and height in the course of the measured turbidity. Due to these jumps, the control device can detect the outflow of small amounts of liquid 7 and the risk that the pump 3 could suck in air and thereby emit disturbing slurping noises.
  • the Abpumpvorgang can be independent be terminated by the evaluation method used the Abpumpvorgang as soon as the Level of the liquid 7 has dropped below the installation of the turbidity sensor 5, 6.
  • Another possibility is the sinking of the liquid level, the pump 3rd only temporarily switch off.
  • the drain pipe 2 becomes liquid again Fill 7 and the liquid level above the measuring path of the turbidity sensor 5, 6 rise.
  • the pump 3 can be put into operation again for a certain time become.
  • the liquid level has dropped below the turbidity sensor 5, 6, it is possible in FIG In any case, it will usually be pumped for a certain amount of time, as between the turbidity sensor 5, 6 and the pump 3 in the drain pipe 2 a certain amount of liquid. 7 is included, which can be pumped off first, until there is a risk that the pump. 3 could suck in air.
