Description
Technical field
The present invention relates to a kind of foam for the electric current for being used for the drive motor by means of analyzing and processing washing machine to detect
Run washing machine method and it is a kind of be this suitable washing machine.It is used to run the invention particularly relates to one kind and there is cleaning solution
ContainerFor accommodating roller (Trommel), the drive motor for roller and the control of washings
The method of the washing machine of device, further relate to a kind of suitable washing machine for performing methods described.
Background technology
In washing machine, typically for by the cleaning solution comprising detergent come washing stage for cleaning in handle and wash
Thing.In addition, by the wash phase of water (Sp ü lphase) (in the wash phase remove be in washings in or
On cleaning solution and/or dirty) after, the processing of washings is often carried out by water softener (Weichsp ü ler).Here, go out
In cost reason and environmental protection reason significantly, washings inorganic agent is used
The optimal amount of (especially detergent and water softener).But it should also avoid excessive dosageOr dosage
Insufficient (Unterdosierung).It is particularly likely to cause foam overflow by the wrong dosage (Fehldosierung) of detergent(excessive dosage).
In washing machine, often because the mistake of detergent uses, especially the excessive dosage of detergent and for example washs
The wrong choice of program produces excessive foam.This is all harmful at many aspects.Therefore, excessive foam reduces to act on and treated
The relative motion of washings in the power and roller of the washings of processing.
In addition, caused foam also adversely affects to drying process in washing process, because foam is washing
There is braking effect, therefore, the drying stage shows not good enough or dried with relatively low rotating speed between roller and lye container
The drive motor of cleaning-drum is used in during journey, and over-burden and may be damaged to.
If in addition, during the process of washing methods, many foams be present in the lye container of washing machine or
Produced during drying, washing liquid pump (Laugenpumpe) does not promote foam-washing liquid mixture.Therefore, the foam in pumping out is visited
Do not implement to dry during survey or interrupted in the case of the foam detection during drying and dried.In addition, foam can be from washing
Opening (such as the lye container ventilation unit of liquid containerWith filling flexible pipe (Einf ü
Llschlauch overflowed in)).Therefore, foam identification and the efficient measure for eliminating foam ahead of time is important.
For those reasons, the scourability in washing machine significantly reduces.In the case of particularly disadvantageous, foam may be
Overflowed during washing process from washing machine, this may damage the mechanical part and electronic unit of washing machine.In addition, washing
In the holding chamber (Aufstellraum) of clothing machine, furniture, floor and surrounding environment are also damaged.
In order to avoid disadvantages mentioned above, it is known that the different feasible programs for being used to identify or eliminate foam.
Usually, in order to identify the formation of foam, the pressure in lye container is measured by sensor.Generally, it is this
Using pressure sensor, pressure sensor can be also suitably used for determining the level in lye container.Often, by washing or drying
When pressure texture or the pressure slowed down significantly during by pumping out reduce to detect the presence of foam (liquia air mixture).

Output signal is the mark for the formation of foam during drying process and shows as the drive motor for cleaning-drum
And it thus be accordingly used in the adjustable parameter for the regulation for drying rotating speed.Pressure sensor be with lye container and therefore with washing machine
The part of the pipeline of cleaning solution system connection.If know by the rise of pressure sensor measurement cylinder hydraulic pressure and therefore
Formation of foam in other cleaning solution system, then trigger the corresponding switch step of the drive motor for cleaning-drum
(Schaltschritte)。

It is measurable at pressure sensor to detect that (Luftabschluss) is terminated by the air thus detected of detector housing
Pressure improves.Become known for identifying the method for foam based on boundary value (pressure threshold) is exceeded, this is used to record depositing for foam
And typically consider be used for trigger the removal of foam measure.
The shortcomings that known method be accumulated due to washings and during drying existing for remaining water imbalance,
The illusion risen by the pressure of falseness causes measuring error.Even if there is no foam completely, also may be used by the appearance of pressure peak
The presence of foam can be shown.This is due to the fluctuation in the pressure measxurement by sensor, wherein, signal receives, signal conversion
Or the mistake in signal transacting depends on：Whether digital governer or analog regulator are used.Because negative value once in a while is not by passing
