Definitions

  • the invention relates to a method for monitoring a load of a laundry drum of a tumble dryer, see, for example DE19832292A1 and / or for monitoring a degree of drying of items of laundry introduced into the laundry drum, wherein the laundry drum is driven by means of an electric motor having a stator with at least one winding.
  • the invention further relates to a corresponding circuit arrangement and a tumble dryer with such a circuit arrangement.
  • umble dryer also includes a washer-dryer which is used for washing and drying items of laundry.
  • the remaining drying time is determined, then a time at which the drying of laundry is stopped can be predicted.
  • the drying time of the laundry is known to be related to the loading of the laundry drum. At the beginning of each drying process, this load is made up of the dry mass of the laundry items brought into the laundry drum and the mass of water, ie. H. the mass caused by the moisture of the laundry items.
  • a loading of a laundry drum of a tumble dryer and / or a degree of drying of laundry items introduced into the laundry drum are monitored.
  • the laundry drum is driven by means of an electric motor which has a stator with at least one electrical winding.
  • the electric motor is controlled by means of a control device by applying electrical voltage to the at least one winding of the stator.
  • An electric current flowing through the at least one winding when the electric motor is driven is measured by means of the control device, and conclusions are drawn as to the degree of drying of the laundry items and / or the loading of the drum depending on measured values of the current.
  • the invention is thus based on the finding that an electric current flowing in the winding of the stator when the electric motor is driven constitutes a measure of the loading of the laundry drum and thus a measure of the degree of drying of the laundry items.
  • the loading of the laundry drum and the degree of drying of the laundry items can be determined particularly accurately. It can thus be accurately determined or even regulated a remaining drying time, which is required for drying the laundry.
  • an energy delivered to the electric motor can be calculated. Then it is possible to deduce the degree of drying of the items of laundry and / or the loading of the drum as a function of a progression of the energy over time.
  • a power delivered to the electric motor ie the energy per unit time, depends directly on the load of the laundry drum or on the moment of inertia of the same. This means that in wet laundry more power must be delivered to the electric motor than dry laundry. Does the power delivered to the electric motor no longer change? so it is an indication that the laundry is already dry. In a time course of the energy delivered to the electric motor, it can be seen by a constant slope of the course.
  • the laundry drum is driven by means of a permanent-magnet synchronous motor whose rotor carries at least one permanent magnet.
  • the speed of such synchronous motors can be particularly simple, z. B. by means of an inverter, control or regulate.
  • the speed behavior of the electric motor can be controlled depending on the respective current degree of drying of the laundry items and / or the current loading of the drum.
  • At least two control scenarios are provided here:
  • the speed behavior of the electric motor can be regulated with regard to the remaining drying time required for drying the laundry items.
  • the speed behavior with respect to a power consumption of the electric motor can be controlled. These two control scenarios can be made available to an operator when operating the tumble dryer, for example.
  • the operator defines a point in time at which a drying process is to be ended. Then, the speed behavior of the electric motor is controlled by the control device so depending on the measured values of the current that on the one hand the drying process is terminated at this time and on the other hand, the power consumption of the electric motor is minimized.
  • a difference between a measured value of the current detected during the first time interval and a measured value of the current detected during the second time interval is preferably calculated, and depending on this difference, conclusions are drawn as to the degree of drying of the laundry items and / or the loading of the drum. This is based on the recognition that the loading of the laundry drum changes during a drying process with time, as the laundry items lose moisture - the mass of the laundry items approaches the dry mass. Then during the drying process, less and less torque is required to drive the laundry drum or the moment of inertia of the laundry drum is getting smaller. Since the motor current is proportional to the torque, the measured values of the current flowing through the winding of the stator become ever smaller during the drying process. In this way, the change in the loading of the laundry drum and thus the change in the degree of drying can be monitored. If the measured values of the current change only slightly or even no longer, it is an indication that the items are already dry.
  • a difference between an average of the current intensity during the first time interval and an average value of the current during the second time interval is calculated, and depending on this difference, the degree of drying of the laundry items and / or the loading of the drum is deduced Accuracy of the monitoring of the loading and / or the degree of drying.
  • Current peaks that may possibly occur in the course of the current are compensated for by the formation of the mean values.
  • an initial load of the laundry drum can also be determined.
  • the initial load of the laundry drum can be determined depending on these measured values of the current.
  • the drying time required for drying the laundry items can thereby be estimated.
  • an overload of the laundry drum can be detected and the operator can be signaled. It is preferably provided that when the initial load exceeds a predetermined value, a warning signal, eg. B. an optical or an acoustic signal is output.
  • phase delay between the phase of the voltage applied to the at least one winding of the stator and the phase of the measured current can be calculated, and depending on the phase delay, the degree of drying of the laundry items and / or the loading of the drum can be deduced.
  • the detected measured values of the current and / or the calculated energy and / or the phase delay can be compared with a characteristic stored in a memory. Values for the loading of the laundry drum and / or for the degree of drying of the laundry items can thus be read from a characteristic curve.
  • Another possibility here is a mathematical model in which the values for the loading of the laundry drum and / or the degree of drying of the laundry items are calculated on the basis of a mathematical formula depending on the detected measured values of the current and / or the energy and / or the phase delay.
  • a circuit arrangement according to the invention is designed for monitoring the degree of dryness of laundry items introduced in a laundry drum of a tumble dryer and / or for monitoring a loading of the drum.
  • the circuit arrangement comprises an electric motor whose stator has at least one winding which is coupled to a control device.
  • the control device is for measuring a current flowing through the at least one winding and the current Detecting the degree of drying of the laundry items and / or the loading of the drum is formed depending on the detected measured values of the current.
  • the invention also includes a clothes dryer, which has a circuit arrangement according to the invention.
  • Fig. 1 a block diagram of a circuit 1 is shown.
  • the circuit arrangement 1 comprises a power supply unit 2 which has, for example, a bridge rectifier.
  • the power supply 2 is connectable to a power supply network.
  • a rectified electrical voltage is provided.
  • the circuit arrangement 1 furthermore has an inverter or inverter 3 with a plurality of insulated gate bipolar transistors.
  • the inverter 3 comprises six such bipolar transistors.
  • the inverter 3 is controlled by a control unit 4.
  • the inverter 3 and the control unit 4 together form a control device.
  • the circuit arrangement 1 also includes a permanent-magnet synchronous motor 5, the rotor carries permanent magnets and the stator is designed to be three-phase.
  • the stator thus has three windings 6 in the example.
  • the windings 6 are coupled to the inverter 3.
  • AC voltage for all windings 6 of the synchronous motor 5 can be provided.
  • the control unit 4 can detect a current I flowing through the windings 6. In this case, different embodiments are provided. Only the current I flowing through one of the windings 6 can be detected. Alternatively, currents I flowing across all the windings 6 of the stator can be measured separately. Finally, a summation current can be measured, i. H. All currents I can be tapped from the respective windings 6 and added up.
  • FIGS Fig. 2 and 3 A method for monitoring a load of a laundry drum of a clothes dryer, which the circuit arrangement 1 according to Fig. 1 Now, as well as for monitoring a degree of dryness of laundry items loaded in the laundry drum, reference will now be made to FIGS Fig. 2 and 3 explained in more detail.
  • the current I flowing through the winding 6 can be measured and evaluated by means of the control unit 4.
  • An exemplary course of this current I is in Fig. 2 shown.
  • the time t is plotted on the x-axis.
  • the laundry drum of the tumble dryer is repeatedly accelerated and decelerated by means of the synchronous motor 5. This can be seen on the basis of the pulse-shaped current profile:
  • the laundry drum is accelerated for the first time until it reaches a predetermined speed.
  • the laundry drum is rotated during a time interval 8, in order then to be decelerated at a time t 1 .
  • current I flows through the windings 6. This current has an approximately sinusoidal profile.
  • the laundry drum is repeatedly accelerated and decelerated during the time interval 7 of the entire drying program, being rotated during the respective time intervals 8 to 12.
  • Characteristic of the course of the current I during the respective time intervals 8 to 12 is a current spike 13 which occurs at the beginning of each time interval 8 to 12.
  • the loading of the laundry drum and the degree of drying of the laundry items are monitored.
  • the current intensity of the current I is measured.
  • the current peak 13 of the current I is measured.
  • This current is a measure of an initial load of the laundry drum, which is composed of the dry mass of the laundry items and from the moisture.
  • This initial load is compared to a threshold and a warning signal is given when the initial load exceeds the predetermined threshold. From the initial load also required for the drying of the laundry items time, ie the time interval 7, calculated or estimated.
  • the current intensity of the current I is also monitored during the further time intervals 9 to 12.
  • the current load of the laundry drum is determined depending on the current.
  • the loading of the laundry drum at any time during the time interval 7 is known: It can either be calculated using a mathematical function depending on the current intensity of the current I or read from a characteristic or table by means of the control unit 4.
  • the degree of drying of the laundry is to be monitored depending on the course of the current I.
  • a change in the current intensity of the current I during the time interval 7 is monitored.
  • a difference between an average value of the current I detected during the time interval 8 and an average value of the current I detected during the next time interval 9 can be calculated.
  • This difference is then a measure of the change in the degree of drying of the laundry items.
  • the change in the current intensity of the current I during the entire drying process, ie during the time interval 7, is in Fig. 2 illustrated by a line 14. If the course of the line 14 is constant, ie the current intensity of the current I no longer changes, the items of laundry no longer lose any water. This is an indication that the laundry is already dry. The drying process can thus be ended at a time t 2 .
  • the current intensity of the current I is directly related to a torque of the synchronous motor 5. Both quantities, current I and torque, can be considered equal. If only one of the two quantities is mentioned, the statement can also be transferred to the second size.
  • an output to the synchronous motor 5 energy represents a measure of the degree of drying of the laundry items and the loading of the laundry drum.
