Certainly.The preferable configuration of the present invention is enumerated in the corresponding dependent claims.The preferable configuration of methods described is corresponded to and washed
The preferable configuration of clothing machine, even if not pointed out herein to this separately.
Therefore, it is used to run a kind of method of washing machine the present invention relates to a kind of, the washing machine has container, for connecing
Receive the roller of washings, the drive motor for roller, in a reservoir be used to measure with waterborne liquid in a reservoir into
The electrochemistry and control device for the electrochemical signals that split-phase is closed, wherein, perform following steps：
(a) waterborne liquid containing detergent is provided in a reservoir；
(b) rotate roller according to predetermined motor program；
(c) terminate the rotary motion of roller and make the waterborne liquid containing detergent steady (Ruhenlassen), until
Untill the previously given plateau (beruhigter Zustand) for reaching the waterborne liquid for containing detergent；With
(d) by using the correlation being stored between in control device, electrochemical signals and detergent concentration
In the case of receive and the electrochemical signals of analyzing and processing electrochemical sensor, measure provided in step (a) containing washing
Wash the concentration c of the detergent in the waterborne liquid of agentten。
Herein, term " waterborne liquid containing detergent " can be construed broadly as.Herein, detergent represents detergent
Itself, including its Ingredients Surfactant, enzyme, bleaching agent etc. and softening agent.In addition, the waterborne liquid containing detergent
It can be referred to as according to the stage (in this stage, the waterborne liquid containing detergent gathers) in washing procedure
Washing alkali liquid, such as free rinsing liquid or flushing liquid.
In addition, under meaning of the present invention, container is interpreted as alkali liquor container, the part of container or part, is transporting
The waterborne liquid provided during row washing machine is located in part/part of the alkali liquor container/container or passed through from its side
Flow with crossing.Therefore, impedance transducer can be arranged in the alkali liquor container of washing machine and be arranged in measurement container in or
It is arranged in liquid line, the measurement container is fluidly connected with alkali liquor container, operation of the waterborne liquid in washing machine
Period is flowed via the liquid line.It will be led when washing machine has during operation of the waterborne liquid in washing machine from alkali liquor container
When going out and supplying the circulating pump system of alkali liquor container again, the above situation can be especially advantageous.
As the measurement to previously given plateau, it may be considered that for example convection current (Konvektion) is to waterborne liquid
In course of conveying contribution.
In order to determine the fully plateau of waterborne liquid, it may be considered that such situation：A variety of electrochemical measurement sides
Method produces electrochemical signals under the inactive state of waterborne liquid, and faraday's electrolysis sections of the electrochemical signals passes through water-based
The diffusion (Diffusion) of electroactive grain kind (elektroaktiven Spezies) in liquid determines.If aqueous solution
Body is not at static, then electroactive grain is planted to the conveying of electrode and no longer only caused by diffusion, and is also influenceed by convection current.This is logical
The change of the characteristic of electrochemical signals is often resulted in, wherein, the change is the measurement that convection current is made to contribute.Therefore, by dividing
Analysis processing electrochemical signals can be inferred that the contribution of convection current and speculate that aqueous liquid may not fully steady shape
State.Suitable electrochemical signals can be measured for example by means of the method for voltammertry.Here, this electrochemical signals can example
Such as by using cyclic voltammetry (Cyclovoltammetrie), amperometry (Chronoamperometrie) or double
Pulsed amperometric method (Doppelpulschronoamperometrie), but also by impedance spectrometry
(Impedanzspektroskopie) obtain.
In cyclic voltammetry, from the voltage on beginning voltage, the working electrode of electrochemical sensor until so-called
Reversal potential Uλ(so-called " scanning (Hinsweep) forward ") is changed, the reversal potential pair with generally constant speed
In oxidizing process or reduction process be enough.Then, the direction that voltage changes is reversed and voltage is again towards beginning voltage
It is changed (" toward flyback retrace (R ü cksweep) ").The electric current occurred herein is generally improved to peak I when scanning forwardp, so as to
Then until reversing potential UλIt is declined to become value Iλ.Here, when being diffused control to Electrode Operation process, proportionate relationship Ip/IλIt is logical
It is often characteristic parameter Ip/Iλ theor.If the solution of stand-by Voltammetry inspection is in motion, it means that convection current is deposited
The convection current typically results in Ip/IλReduce.As a result, the value I measured at that timep/Iλ realOr difference DELTA I=Ip/Iλ theor-Ip/Iλ real
The measurement that can generally make to contribute as convection current is considered as and used with the measurement therefore as the plateau to waterborne liquid.
In amperometry, the voltage step (Spannungssprung) and then of suitable voltage is generally gone to
Electric current is reduced and measures and analyzes and processes according to the time, the suitable voltage is sufficiently used for oxidizing process and reduction process.
Here, the contribution portion of convection current typically results in the decay of electric current reduction.In dipulse amperometry, beginning is then skipped back to
Voltage and electric current is reduced again at starting process voltage according to the time measure and analyze and process.
Therefore, in a kind of preferred embodiment of the method according to the invention, electric current electricity is mapped out in step (c)
Line buckle as the measurement to plateau, and is not just by the electric current share caused by the diffusion to electrochemical sensor
For analyzed and processed.
Particularly advantageously, therefore, surveying and drawing cyclic voltammetry curve figure (Cyclovoltammogramm), also, it is not just logical
Cross to the electric current share caused by the diffusion of electrochemical sensor, in scanning forward to reverse potential UλWhen peak value electricity
Flow IpAnd reversing potential UλThe electric current I at placeλAnalyzed and processed.
To this alternately or additionally, can be using performing potential step and right in the case of electrochemical sensor
Resulting current-time curvel is on being analyzed and processed by spreading caused share herein, as to aqueous solution
The measurement of the plateau (lacking steady) of body.Here, carry out especially to the potential step of a potential, at the potential, water
Part in property liquid reversibly or irreversibly is aoxidized or reduced.
If the potential referred to herein on electrochemical sensor changes, especially refer to：Forming the electrochemistry
Potential on the working electrode of the electrochemical sensor of sensor changes.Correspondingly, refer to：Referring to the material of working electrode
Diffusion and convection current in terms of conveying.
In a kind of particularly preferred embodiment of the method according to the invention, detergent will be contained in step (c)
The predetermined period Δ t of waterborne liquid steady oneset.Herein, in order to determine Δ tset, it is considered preferred to the amount of waterborne liquid,
The useful load of washings and/or performed motor program in step (b), wherein, consideration has been stored in the control device, time
Section Δ tset, the amount of waterborne liquid, the correlation between the amount of washings and/or performed motor program in step (b).
The amount of waterborne liquid can be asked for for example by the water being imported into by means of water counter measures in container,
Wherein it is possible to the part absorbed in view of the washings of the water of importing, also, for example ought be disposed with a reservoir hydrostatic
Pressure sensor and when being considered for measuring the hydrostatic pressure as to the measurement of free rinsing liquid, can
To ask for so-called free rinsing liquid (freie Flotte).
The useful load of washings can be adjusted by user and set, or but can the preferably automatically quilt in washing machine
It is determined that.Herein, the determination of useful load can weight increase be entered caused by the loading of washings by measurement cylinder
OK, or but can also be carried out by analyzing the suction properties of water, its mode is, on dry washings is added water to
Period, analyze the change of hydrostatic pressure.Therefore, it is advantageously provided with hydrostatic according in the washing machine of the present invention a kind of
Sensor.Particularly advantageously, water counter also is provided with, that is, is used to ask for loaded water or the washing soda loaded
The measuring apparatus of liquid measure.It may be thus possible, for example, to compare by means of the hydrostatic pressure p measured by hydrostatic sensor and institute
The water of loading.Washings in roller absorbs water.Absorbed water may not make contributions to the raising of hydrostatic pressure.
Pass through relatively measured hydrostatic pressure p and the water injected --- absolute value and its change in time --- with
Accordingly, value in the control device of washing machine, being impregnated with for washings is stored in, the useful load of washings can be asked for
Its saturation (degree of wetting) can be asked for if necessary.
In another preferred embodiment, in order that the waterborne liquid containing detergent steadily contains until reaching described
There is the previously given plateau of the waterborne liquid of detergent, it is contemplated that existing amount or dense of the electrochemical signals to foam
The dependence of degree.Here, presence and the amount of foam can be asked in a different manner.
For example, the detection of the foam in washing machine can pass through electricity by two electrodes in the region of the lower section of container
Measurement is led to carry out.In addition, can be by means of realizing bubble to the analyzing and processing of specified/actual speed difference when basket centrifuges are dehydrated
Foam detects.Herein, such situation is made full use of：Foam can brake the roller rotated, thus cause in rated speed
Difference between actual speed.Herein, it is determined that consistency of foam and specified/actual speed difference between corresponding relation lead to
Often it is stored in the control device of washing machine.Generally, by the pressure build in washing either centrifugal dehydration or by
The pressure drop reduced strongly when pumping out is so as to detecting the presence of foam (liquid-air mixture).
Generally, in order to identify the formation of foam, the hydrostatic pressure in container is measured by means of sensor.Therefore,
Usually using pressure sensor, especially hydrostatic pressure sensor, the pressure sensor also is adapted for as mentioned above
In it is determined that water level in container.Here, the injustice based on washings Yu remaining water that is existing, being gathered during centrifugal dehydration
Weighing apparatus, by bogusFalse pressure rise and cause measurement error.Can be with by the appearance of pressure peak
Show the presence of foam, even and if being not present foam.This is attributable to the fluctuation when carrying out pressure measxurement by sensor, its
In, the error when signal is received, signal is changed or signal transacting using digital governer also with still using analog regulation
Device is related.Because accidental negative value can't be detected by a sensor, therefore be asked for less than real average value (if can examine
Negative part is measured, then may draw the real average value), and ask for vibrating the pressure of the raising of water.In addition, by
Signal measured by pressure sensor raises with rotating speed, previously given so as to cause prematurely to exceed to identify foam
Pressure threshold.Hence it is advantageous to which the foam in washing machine can be identified, its mode is, in roller with high rotating speed UnRotation
By for determining to be located in container and the sensor measurement signal S of the signal of the liquid of foam may be included between refundingnAnd
By its with it is being stored in presetting apparatus, corresponding to rotating speed UnValue WnCompare, wherein, in control device, for
At least two rotating speeds are stored with value to UnAnd Wn(n >=1), also, up to or over value WnWhen (meeting condition Sn≥Wn
When), record the presence of foam.Although this sensor can be optical measuring system, measure electrical conductivity measuring system or
The measuring system of person's electric capacity.Preferably hydrostatic pressure sensor, in the described hydrostatic pressure sensor, as letter
Number, preferably measure the liquid in hydrostatic pressure p and/or hydrostatic pressure negative gradient (dp/dt) in time, container
The preferred hydrostatic pressure p of body-air mixture.Signal SnWith corresponding value WnEspecially pressure value.
Therefore, in a kind of preferred embodiment of the method according to the invention, asked with hydrostatic pressure sensor
Take presence of the foam in waterborne liquid and considered the plateau for determining waterborne liquid.
In addition, the presence of foam also shows in electrochemical signals.That is, if foam is before electrode, surveyed
The electric current of amount generally reduces.Therefore, can be as to foam be present in the quantity and duration that this unexpected electric current reduces
Measurement is considered, wherein it is possible to suitably extend for stable time interval Δ t (also referred to as " commutation interval " or " roller
Idle periods "), untill consistency of foam returns to acceptable numerical value.
The method used to detect foam generally depends on：Which (especially soaked in stage of washing procedure
Wet stage, washing stage, rinse stage or submissive stage) it is ensured that aqueous solution is fully steady, thus, it is possible to receive
Effective electrochemical signals.
If pressure sensor (especially hydrostatic pressure sensor) is present in used washing machine, can also
Consider the pressure measured during plateau (i.e. roller idle periods) due to the waterborne liquid dripped from washings
Improve as to the stable measurement of waterborne liquid.That is, increase over time, the amount of the liquid of drippage reduces.
According to the present invention, in previously given predetermined period Δ tsetIn the case of, it can be advantageous to set, borrow
Help electrochemical sensor inspection：The fully steady of waterborne liquid actually whether occurs.This can as mentioned above
It is being conveyed by the material asked for working electrode, carried out by the share caused by convection current.If it is not the case, then may be used
To adjust and especially extend predetermined period Δ tset.Here, it can be advantageously provided, no more than the time of maximum
Section Δ tset max.Up to or over Δ tset maxWhen, advantageously adjust the motor program of roller and especially reduce mechanical energy
Introducing.Through this it is achieved that the too long of period is not needed to be used for the rotation of roller intermittently.
The introducing of mechanical energy is carried out by the suitable motor program of roller.The method according to the invention the step of (b)
In motor program especially include turn-on time [in units of %], the duration [in seconds] of commutation cycle and roller
Rotating speed [rev/min].Turn-on time is such time quantum in the stage of washing procedure：Roller is in the time quantum phase
Between rotate.The turn-on time is preferably 60% to 70% for example in the first rinsing step.When commutation cycle is typically such
Between section, the period produces by following time section：Roller rotates in one direction, roller is static, roller is opposite
Side rotates up, roller is static.
For sufficiently smoothly determining and especially predetermined period Δ tsetConfirmation, also advantageously consider
The type of the measuring method of electrochemistry used in step (d), because the measuring method of electrochemistry may need waterborne liquid
Different time of measuring and inactive state.
When, there is when relatively little of pollutant and/or foam, electrochemical signals connect in waterborne liquid to be checked
Receipts are especially accurate.Especially, especially such case in the wetting phase neutralising flush stage.Therefore, according to this hair
In a kind of preferred embodiment of bright method, in wetting phase and/or the execution step (c) and (d) in rinse stage.
Herein, wetting phase is interpreted as such stage in washing procedure, in this stage, to be cleaned and outstanding
The washings of its stand-by washing alkali liquid washing is soaked by the washing alkali liquid for this, usually until washings washing soda
Untill liquid saturation.Herein, washings does not move mostly just weakly or completely.Therefore, in wetting phase mostly just
Small separation of the pollutant from washings to be washed occurs.Especially washings roller in wetting phase preferably not with more than every
Minutes 25 turns of revolution and rotate.Herein, " washing alkali liquid " and " waterborne liquid containing surfactant " generally has phase
Same implication.Term " surfactant " used herein represents the surfactant of single and different surface-actives
The mixture of agent.
Waterborne liquid is made by motor program to move to a certain degree and therefore roller idle periods then are required
, the presence for the washings carrying piece that this degree is also depended in roller and shape.If the shape of washings carrying piece
It is asymmetric, the then contribution of its motion to waterborne liquid and rotation side in the case where the rotary speed of roller is previously given
To correlation.Therefore, in the case of using being asymmetrical in shape of washings carrying piece in roller, at least consider that roller is rolling
Direction of rotation before cylinder idle periods.
, according to the invention it is preferred to step (c) is performed in the case where considering the pollution type of washings and/or contaminant capacity
And/or step (d), wherein, different pollution types and/or contaminant capacity for washings in control device are stored with electrification
Learn the correlation between signal and detergent concentration.
Such as it may result in the case where being polluted by the oil：Especially non-ionic surfactant can be more or less bright
It is dissolved in aobviously in oil, and is no longer possible to be detected when measuring detergent concentration.On the other hand, the surface of ion is lived
Property agent can be intercepted (consume) to a certain extent by the pollutant comprising ion, so as to when measuring electrochemical signals they
No longer it is detected.
Pollution type and/or contaminant capacity can adjust setting by the user of washing machine, or but can be by suitable
