Definitions

  • the present invention relates to a method for detecting inadmissible operating states in electronically controlled tumble dryers, especially the state of movement the laundry drum, in which the electrical conductivity of the laundry means Electrodes are determined, which at least temporarily touch the laundry, and the Changes in guideline values are observed to make a decision from a change about continuing operations.
  • a tumble dryer In a tumble dryer, laundry is placed in a drum, the drum in motion set and heated air moves through the drum, causing the laundry moisture withdrawn and thus dried.
  • Critical conditions can arise during the drying process, for example the drive of the laundry drum has a malfunction, for example when Tearing the drive belt of the laundry drum is the case, causing a normal Drying process is prevented.
  • This malfunction is caused by the tumble dryer existing temperature measurement not recognized because all temperature controllers continue to flow around with the normal amount of process air and thus also set normal temperatures.
  • the generic method is known from DE 34 36 342 A1. This method is to solve the task of inadmissible operating conditions with the available means detect. This is done when determining a change in measurement data on the residual moisture started the counter of the laundry to be dried and started again and again, if another change is found. This counter has a fixed default Overflow status and is reinitialized again and again as long as within the fixed counting interval until the overflow status is reached, another change of the Measurement data is determined. This means that when observing the measurement data depends on changes and their timing in relation to the last one Change of measurement data. In the known method, in a case where the Drum stands still, the laundry, e.g. B., under the influence of the still blowing drying air still move to a limited extent and have different levels of moisture Apply areas to the electrodes so that a change in the measurement data is detected and operation continues despite the impermissible operating state.
  • the present invention is therefore based on the object of a method of the beginning Specify the type mentioned, in which additional components such as scanning elements and Switches can be avoided and in the simplest way using existing ones Components of the impermissible operating state can be detected. In doing so can be avoided if the laundry is moved while the drum is at a standstill operation is maintained.
  • the method for recognizing impermissible operating states is distinguished characterized in that the conductance periodically during the drying process is detected, the current recorded conductance with at least one previously recorded Conductance is compared and if the change determined from the compared values of the master value over a multi-periodic period corresponds to a small fluctuation range, an indication of the standstill of the Laundry drum is done.
  • the low Fluctuation range preset depending on the load of the laundry drum This has the advantage that an inadmissible shutdown of the drying process is avoided when rotating the drum. With very large loads and in particular at the beginning of the drying process when the laundry is very damp result that there is constantly wet laundry on the electrodes and the change of the conductance is therefore very low. The fluctuation range then becomes correspondingly small of the master value is preset.
  • this fluctuation range can also be zero or be substantially zero.
  • the laundry drum 1 has a measuring electrode 12 on; the drum 1 itself serves as the second electrode.
  • the drum 1 is connected to the mass 4 of the dryer and the electrode 12 connected to a constant voltage 5 via a series resistor 13.
  • the Washing the drum 1 has a laundry resistance 14, which on the one hand has the Drum 1 with the mass 5 of the dryer and on the other hand via the electrode 12 is sporadically connected to the resistor 13 and thus to this one Forms voltage divider.
  • a measurement signal 15 is obtained, which is a measure of the laundry conductance serves.
  • This conductance measurement signal can advantageously with the input of a Anti-aliasing filter 2, the output of which is connected to an analog input Microcontroller 3 is connected.
  • Conductivity measurement signal 15 results. Every time the electrode 12 is touched by a piece of laundry or any change in between the electrode 12 and the drum 1 measured laundry resistance 14, the conductance measurement signal jumps or have an impulse. In cases where there is no laundry the electrode 12 touches or a piece of laundry touches the electrode very little, and therefore a lower conductance is determined, the conductance measurement signal has a minimum value. With a very good electrical connection between the electrode 12 and the laundry in contrast, a signal 15 has a maximum value.
  • drum 1 comes to a standstill due to faulty drive, the conductance changes no longer or only insignificantly, since either one and the same item of laundry is always on of the electrode 12 or, if this is in the upper region of the drum, no items of laundry are in permanent contact and the conductance is therefore zero.
  • the microcontroller 3 thus checks whether the conductance fluctuates and whether it changes Fluctuation is greater than a preset small fluctuation range or a constant value (zero). Is the determined value or the determined change of Conductance in the preset low fluctuation range, an indication is given of the stoppage of the washing drum. At the same time or accordingly thereafter Drying process interrupted.
