Definitions

  • the invention relates to a method for controlling a door opening device of a household appliance and a door opening device in a household appliance according to the preambles of the independent claims.
  • the invention relates to a household appliance with such a door opening device.
  • Household appliances for the care of laundry items which have an interior which can be closed by means of a door usually have a locking device which holds the door in a closed position by means of a force fit.
  • Modern household appliances can be equipped with an electromechanical door opening device for exerting a pressing force on the inside of the household appliance door in order to overcome the frictional connection exerted by the locking device.
  • a household appliance with such a door opening device is from the DE 10 2013 223 431 B3 as well as from the DE 10 2014 201 924 A1 known.
  • JP 2008-032323 A which is considered the closest prior art, a refrigerator with a door opening device, and the document DE 10 2012 010 929 A1 discloses a locking device for a door of a domestic washing machine.
  • the invention is based on a method for actuating a door opening device comprising an electromechanical actuator of a household appliance comprising a door during an opening process, the actuator comprising two actuator connections for electrical actuation.
  • the method comprises providing an electrical supply voltage between an electrical supply connection and an electrical reference connection of the door opening device, which has a voltage form specified in an intended operating state of the household appliance, providing an electrical coupling device for coupling, if necessary, a first of the two actuator connections to the supply connection and / or a second of the two actuator connections to the reference connection.
  • the method comprises coupling the supply voltage and the two actuator connections by means of the coupling device as a function of a pulse-shaped coupling signal for the electrical control of the actuator and generating a pressing force for acting on the door as a function of the electrical control of the actuator.
  • the electromechanical actuator can be an actuator with a magnetic coil connected between the two actuator connections, preferably with a solenoid, which can be controlled such that a magnetic force can be exerted on a movable actuator element.
  • the movable actuator element is preferably a magnetizable material, in particular a ferromagnetic material.
  • the movable actuator element can be arranged in such a way that in a rest position it is mounted at least partially outside an inner region of the magnet coil and is pulled in the direction of the magnet coil when the actuator is electrically actuated.
  • the attraction is based on the reluctance force, which is based on the change in the magnetic resistance.
  • the resulting force is proportional to the square of the current that flows through the magnetic coil and generates the magnetic field.
  • the force acting on the movable actuator element is therefore independent of the sign of the current through the magnetic coil, which makes such an embodiment of the electromechanical actuator usable for direct control with an alternating signal (AC).
  • AC alternating signal
  • the use of a permanent magnetic material for the movable actuator element can be provided, which is the case when using an electrical Supply voltage in the form of an AC voltage requires an additional rectification for electrical control of the solenoid.
  • the method is developed further by generating the pulse-shaped coupling signal as a function of the predetermined voltage form and / or as a function of the coupling device provided in order to achieve a time profile of the pressing force, which has an increasing envelope.
  • envelope is understood here to mean a curve that touches the graph of the temporal course of the pressing force in each case close to a local minimum.
  • the envelope is a sequence of straight lines.
  • the envelope curve can also be determined by connecting the respective local maxima by the straight line segments. In this case it can happen that the envelope does not touch the graph of the temporal course of the pressing force in the vicinity of the local maxima, but intersects, the deviation from an "ideal envelope" being negligibly small.
  • the envelope curve can thus be described by an interpolated, in particular linearly interpolated, course of the local maxima with a positive sign of the graph of the time course of the pressing force.
  • the invention is based on the finding that, with controls which are usually used for such door opening devices and which are based on an electrical alternating voltage and which allow a very simple implementation of a control circuit on the basis of a triac or a relay, restrictions with regard to the adjustable time characteristic of the pressing force subject to.
  • a current implementation of a door opening device uses an extra pin to push / push the door from its closed position.
  • This pin is guided by the control of a magnetic coil.
  • the pin and the magnetic coil require a certain force to overcome the holding force of a door locking device.
  • the energy required to open the door must be made available within half a period (10 milliseconds at 50 Hertz). This means that enough energy must be available within approximately 10 milliseconds. After that, the energy in the magnetic coil does not continue to rise.
  • the operating time of a shock has a greater dependence on the frequency.
  • vibrations can occur due to the zero crossings, in which the current through the magnet coil becomes zero.
  • the door, the household appliance and the door holding mechanism are mechanical parts which are assembled. Therefore, they may absorb a rapid shock from the door opening device by forming a mechanical filter for a shock lasting up to 10 milliseconds.
  • a large current pulse is required to control the actuator.
  • voltage fluctuations can lead to different impact forces due to the different energy that is provided to the magnet coil within the 10 milliseconds. A fine adjustment for voltages between 170 volts and 260 volts is therefore not possible. In return, to ensure that the door opens in any case, even at a low voltage of 170 volts AC, an oversized shock at 260 volts AC can be expected.
  • the electrical coupling device has a resistance element with a variable electrical resistance that is electrically connected in series with the actuator.
  • the variable electrical resistance is a temperature-dependent resistance, preferably a thermistor (NTC), the resistance value of which has a negative temperature coefficient.
  • NTC thermistor
  • Such a resistance element can be used both with an electrical supply voltage in the form of a DC voltage and with an electrical supply voltage in the form of an AC voltage.
  • the provision of the coupling device and the generation of the pulse-shaped coupling signal are carried out in such a way that the time course of the pressing force during an active pulse phase of the coupling signal has a sequence of at least two local maxima, which are in each case on or near the increasing envelope , a second local maximum of the at least two local maxima following a first local maximum of the at least two local maxima later in time having a higher value than the first local maximum.
  • the maximum force exerted on the door can be increased successively.
  • the provision of the coupling device and the generation of the pulse-shaped coupling signal are carried out in such a way that the sequence of the at least two local maxima has a third local maximum that follows the second local maximum and has a higher value than the second local maximum. This allows the graduated exertion of the opening force on the door to be further refined.
  • the electrical supply voltage is provided by a DC voltage source. This results in greater flexibility in the type of actuation of the electromechanical actuator; in particular, the effects of the zero crossings that are inherent when using an AC voltage are eliminated.
  • the electrical supply voltage is provided by an AC voltage source.
  • a rectifier is preferably connected between the supply voltage and the electromechanical actuator.
  • the use of a rectifier when fed from an AC voltage source thus also enables the use of a permanent magnetic material as a movable actuator element.
  • an electrical filter element can be provided behind the rectifier, that is to say on the rectified side to which the actuator is connected, which reduces a reduction in the drops in the time course of the pressing force caused by the zero crossings of the AC voltage.
  • the coupling signal is generated during the opening process with a sequence of a plurality of individual pulses spaced apart in time.
  • the coupling signal can be generated with a single single pulse during the opening process.
  • the shape of the time course of the pressing force and the increasing envelope curve is determined by the electrical coupling element itself.

  • the electrical coupling device has a resistance element with a variable electrical resistance that is electrically connected in series with the actuator.
  • the variable electrical resistance is a temperature-dependent resistance, preferably a thermistor (NTC), the resistance value of which has a negative temperature coefficient.
  • NTC thermistor
  • Such a resistance element can be used both with an electrical supply voltage in the form of a DC voltage and with an electrical supply voltage in the form of an AC voltage.
