Definitions

- a household appliance with such a door opening device is known from DE 10 2013 223 431 B3 as well as from DE 10 2014 201 924 A1.
- the invention is based on a method for controlling a door opening device comprising an electromechanical actuator door opening comprehensive household appliance during an opening operation, wherein the actuator comprises two Aktoran beautifully for electrical control.
- the method comprises providing an electrical supply voltage between an electrical supply connection and an electrical reference terminal of the door opening device, which has a specified in a normal operating state of the household appliance voltage form, providing an electrical coupling device for coupling a first of the two Aktoran say to the supply connection and / or a second as needed the two actuator connections to the reference terminal.
- 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 an urging 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 solenoid coil connected between the two actuator connections, preferably with a cylindrical coil, which can be controlled such that a magnetic force can be exerted on a movable actuator element.
- the movable actuator element is a magnetizable material, in particular a ferromagnetic material.
- the movable actuator element may be arranged so that it is at least partially stored in an inoperative position outside of an inner region of the magnetic coil and is pulled in the direction of the magnetic coil in an electrical control of the actuator.
- 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 flowing through the magnetic coil and generating the magnetic field.
- the force acting on the movable actuator element is thus independent of the sign of the current through the magnetic coil, which makes such an embodiment of the electromechanical actuator also suitable for direct control with an alternating signal (AC).
- AC alternating signal
- the use of a permanent magnetic material for the movable actuator element may be provided, which requires an additional rectification for the electrical control of the magnetic coil when using an electrical supply voltage in the form of an AC voltage.
- the method is developed by generating the pulse-shaped coupling signal as a function of the predetermined voltage shape and / or as a function of the coupling device provided for achieving a time profile of the pressing-on force, which has a rising envelope.
- an envelope is understood as a curve which touches the graph of the chronological progression of the pressing force near a local minimum.
- the envelope is a sequence of straight line pieces. To simplify matters, the envelope can also be determined by connecting the respective local maxima through the straight line segments.
- the envelope may not touch but intersect the graph of the temporal progression of the pressing force near the local maxima, the deviation from an "ideal envelope” being negligibly small, thus simplifying the envelope curve
- the invention is based on the finding that with control systems usually used for the use in such door-opening devices on the basis of an alternating electrical voltage, which has a very high degree of polarity allow simple implementation of a drive circuit based on a triac or a relay, subject to restrictions on the adjustable time characteristic of the pressing force.
- a recent implementation of a door opening device uses an extra pin to push / push the door out of its closed position.
- This pin is guided by the control of a magnetic coil.
- the pin and the solenoid require a certain force to overcome the holding force of a door closer.
- the energy needed to open the door must be made available within the time of half a period (50 hertz 10 milliseconds). This means that enough energy must be available within about 10 milliseconds. Thereafter, the energy in the solenoid does not increase further.
- the provision of the coupling device and the generation of the pulse-shaped coupling signal is carried out such that the time profile of the pressing force during an active pulse phase of the coupling signal has a sequence of at least two local maxima, which are respectively at or near the rising envelope in which a second local maximum of the at least two local maxima that follows at least two local maxima later in time has a higher value than the first local maximum. In this way, successively the maximum force exerted on the door can be increased.
- the provision of the coupling device and the generation of the pulse-shaped coupling signal is carried out in such a way that the sequence of the at least two local maxima has a third local maximum following the second local maximum later in time, which has a higher value than the second local maximum.
- the electrical supply voltage is provided by a DC voltage source. This results in a greater flexibility in the type of control of the electromechanical actuator, in particular eliminates the effects of the inherent when using an AC voltage zero crossings.
- the electrical supply voltage is provided by an AC voltage source.
- a rectifier is connected between the supply voltage and the electromechanical actuator.
- the use of a rectifier when fed from an AC voltage source thus also allows the use of a permanent magnetic material as a movable actuator element.
- an electrical filter element behind the rectifier, that is to say on the rectified side to which the actuator is connected, an electrical filter element can be provided which reduces a reduction of the breaks caused by the zero crossings of the alternating voltage in the time course of the pressing force.
- the coupling signal is generated during the opening process with a sequence of a plurality of temporally spaced apart individual pulses.
- the coupling signal can be generated during the opening process with a single pulse.
- the shape of the time course of the pressing force and the rising envelope is determined by the electrical coupling element itself.
- the coupling signal in response to a first signal which signals an opening state of the door, and / or in response to a second signal, which is a Verneglungsschreib the door signals, generated.
- the door opening device is thus enabled to gently open the door while checking whether the door is already open. In the event that the door is already open, the door opening device would interrupt the actuation of the actuator in order to avoid an additional impact on the door, which could possibly hit a user of the household appliance.
- household appliances can be equipped with a door lock system, which also provides a locking of the door, which is particularly important in a washing machine in the form of a front loader with a front-mounted loading port of considerable importance.
- the door opening mechanism is also suitably blocked in order to prevent damage to components of the household appliance, in particular the locking device or the door opening device.
- the invention is further based on a door opening device in a household appliance comprising a door, wherein the door opening device comprises an electrical supply connection and an electrical reference connection, between which an electrical supply voltage having a predetermined voltage state in the intended operating state of the household appliance can be provided.
- the door opening device comprises an electromechanical actuator for generating a pressing force for acting on the door in response to an electrical activation of the actuator, which comprises two Aktoran beautifully for electrical control, and an electrical coupling device which is adapted to the electrical control of the actuator in Dependence of a pulse-shaped coupling signal to couple a first of the two Aktoran nowadays to the supply terminal and / or a second of the two Aktoran usually to the reference terminal.

- a safety circuit can be implemented, which is designed to effect an interruption of the electrical control of the actuator in the event of erroneous activation of the first electronic switching element by the pulse-shaped coupling signal.
- the signal generation unit can be realized by a program-controlled computing unit, in particular by a microcontroller / microprocessor, which provides the coupling signal to the first electronic switching element.
- the second electronic switching element can be driven in this case preferably by an independent analog circuit, which thus assumes the function of an electronic fuse.
- the signal generating unit is designed to generate the coupling signal as a function of an electrical current through the actuator.
- the current can be regulated by the actuator so that a desired time course results in accordance with a predetermined setpoint profile of the push-on force.

- FIG. 3 is a simplified schematic representation of a modification of the circuit arrangement illustrated in FIG. 2 for use in a door opening device according to the invention in accordance with a preferred first embodiment
- FIG. 4 in a simplified schematic representation of a preferred second embodiment of a door opening device according to the invention.
- a household appliance 1 for the care of laundry items is shown in FIG. 1.
- This can be a washing machine, a tumble dryer or a combination of washing machine and tumble dryer.
- it is a so-called front loader, which has a front-opening door 2, which serves for closing a, for example, circular loading opening 3.
- the household appliance 1 comprises a housing 4, in which a drum 5 is arranged for receiving laundry items.
- the loading opening 3 is a front opening of the drum 5.
- the household appliance 1 moreover comprises an operating device 6 which is to be understood in an embodiment and position by way of example only and not by way of limitation and which has at least one operating element 7 and one display unit 8.
- a drawer-like Ein Togetherschale 9 is shown.
- the pivotally arranged and in particular porthole-like door 2 is in mechanical contact with a arranged inside the household appliance 1 door opening device 10.
- this door opening device 10 is arranged so that it can act on the inside of an edge piece of the door 2.
- This edge piece is opposite to another edge piece of the door 2, on which the door 2 is pivotally mounted on the household appliance 1 by means of a hinge, not shown in FIG. 1.
- the door opening device 10 comprises an electromechanical actuator 1 1, which has a magnetic coil and a movable in the range of action of a magnetic field generated by the magnetic field actuator element of a magnetic or magnetizable material, preferably of a ferromagnetic material.
- the door opening device 10 further comprises a signal generating unit 12, which is designed to provide a pulse-shaped coupling signal to an electrical coupling device 13, which causes the electrical activation of the electromechanical actuator 1 1.
- the opening of the door 2 by means of the door opening device 10 can take place automatically at the end of a washing or drying process, if a correspondingly set program for the treatment of laundry items has expired.
- the door 2 of the household appliance 1 is opened by the door opening device 10 when a user of the household appliance 1 a corresponding operating action via the operating device, for example via a button on the operating device 6 or an input by means of an input element on a touch screen, for example, the display unit 8, makes.
- FIG. 2 shows the electrical part of a door opening device 10, which can be used in a domestic appliance 1 as shown in FIG.
- the door opening device 10 includes a supply terminal 16 and a reference terminal 17.
- the reference terminal 17 may be electrically connected to a neutral terminal (N) of a feeding AC mains network.
- the supply terminal 16 may be electrically connected to an outer conductor terminal (L) of the supplying alternating voltage or three-phase network. Such an arrangement may be powered by a voltage of 230 volts and a frequency of 50 hertz.
- a first actuator port 14 of two actuator ports 14, 15 is electrically connected to the supply port 16.
- a second actuator terminal 15 of the two actuator terminals 14, 15 is electrically coupled to the reference terminal 17 via an electrical coupling device 13 in the form of a first switching element 21, which is designed as a multi-way thyristor triode (triac).
- a supply voltage 18 which has a sinusoidal shape. In particular, this is a voltage of 230 volts with a mains frequency of 50 hertz.
- a pulse-shaped coupling signal 19 takes place an electrical control of the actuator 1 1, which is represented in the illustration of FIG. 2 by its magnetic coil.
- the current through the magnetic actuator is shown schematically as Aktorstrom 20.
- the Aktorstrom 20 has both positive and negative half-waves whose amplitude is equal to each.
- the total energy (W), which consists of the half inductance (L) of the coil, which in turn from the position of the movable actuator element with respect to the magnetic coil of the actuator. 1 1 times, times the square of the current (I) through the actuator 1 1 results (W 1 - L- l 2 ). After that, the energy in the magnetic coil does not increase any further, so that no further increase in force can be achieved for the ejection force.
- the effective pulse duration depends on the frequency. If the solenoid remains activated for a long time, vibrations may occur due to the zero crossings of the actuator current 20 at 0 degrees and 180 degrees phase.
- the door 2, the household appliance 1, and a door holding mechanism are mechanical parts connected to each other. Under certain circumstances, they can largely absorb the effect of a rapid impact by the door opening device 10 having a duration in the range of less than or equal to 10 milliseconds, since they act as a mechanical filter. Therefore, a big pulse is needed.
- Resistance element 22 in Form of a thermistor, which has a temperature-dependent resistance value with a negative temperature coefficient, added.
- the resistance element 22 is thus connected between the first actuator terminal 14 and the supply terminal 16 and replaces the direct electrical connection between the first actuator terminal 14 and the supply terminal 16 as shown in FIG. 2.
- a vibration as a function of the system frequency and the mechanical characteristic may occur given a longer activation period of the actuator.
- Such a tendency to oscillation can be reduced by coupling the magnetic coil of the actuator 1 1 via a full-wave rectifier (bridge rectifier).
- a smoothing element for example a capacitor, behind the rectifier in order to achieve a filtering of power-frequency components from the excitation signal.
- An NTC takes some time to cool down, which results in the system not working so efficiently in the event that the door 2 is to be opened twice within a short time.
- a second embodiment presented below, in this case, provides a more effective way to drive the door opening device 12 by means of DC-powered circuitry.
- a DC voltage is connected to the supply terminal 16 and the reference terminal 17 as the supply voltage 18.
- the supply voltage 18 may here preferably be 175 volts DC to 400 volts DC. These values are not intended to be limiting, but rather any voltage level, in particular less than 175 volts DC, may be provided.
- the coupling device 13, which is coupled in a known manner in series with the electromechanical actuator 1 1, has in the illustrated second embodiment, a first switching element 21 and a second switching element 24, which are connected to each other in series.
- the first switching element 21 and / or the second switching element 24 may be realized as bipolar transistors.
- a freewheeling diode 23 is coupled to the first actuator port 14 and the second actuator port 15.
- the freewheeling diode 23 serves to prevent overvoltage peaks, which may otherwise occur when the first switching element 21 and / or the second switching element 24 are switched off.
- the first switching element 21, which is embodied here as a bipolar transistor, receives the pulse-shaped coupling signal 19 at its base terminal.
- the pulse-shaped coupling signal 19 is designed as a pulse width modulation signal (PWM signal).
- PWM signal pulse width modulation signal
- the coupling signal 19 in each case has a higher pulse width in a subsequent clock cycle than in the preceding clock cycle. This results in an actuator current 20, which has a rising envelope. From the functional relationship, according to which the pressing force is correlated with the actuator current 20, for example, as shown above, a proportionality to the square of the actuator current 20, also results for the time course of the pressing force, an increasing envelope.
- the second switching element 24 represents a safety circuit (PEC). The manner of implementation of this second switching element 24 is not relevant to the invention.
- the relationship between the Aktorstrom 20 and the time course of the Aufdrückkraft generated therefrom may have a very different characteristics depending on the type of electromechanical actuator used 1 1.
- the use of a pulse-shaped coupling signal 19 as a curve train consisting of a plurality of individual pulses thus allows according to the second embodiment, a free adjustability of the curve of the actuator current 20 according to the requirements of a set course of the pressing force.
- the dynamic behavior of the opening process can be optimized in terms of a safe and comfortable operation.
- the illustrated circuitry has several advantages in the door opening process.
- a pulse train with increasing pulse width can be provided to the coupling device 13, for example with a continuous increase from 0 percent to 100 percent duty cycle.
- Different rise curves can be generated depending on the circuit arrangement and the mechanical properties of the actuator 1 1, for example, with a slight overshoot towards the end of the door opening operation.
- the increase of the duty cycle can be adapted to the amount of available DC voltage, which is obtained, for example, for the electrical supply of other components of the household appliance 1 such as a drive motor or a heater from the feeding AC voltage or AC network.
- a better compensation of possible input voltage fluctuations is also possible.
- a slow rise behavior serves to reduce the impression of an abrupt door impact and also to reduce the noise development. If the rise is slow enough, this additional impact does not occur.
- the door opening device can be deactivated immediately in order to avoid a much stronger additional impact on the door already released by the door-holding mechanism.
- the second embodiment offers a significantly higher degree of flexibility and in particular also allows independence from the mains frequency and the mains input voltage.
- a door opening device 10 in particular a DC-controlled door opening device 10 as shown in the second embodiment, can be configured to improve safety and comfort in a door opening operation performed by the home appliance.
- a DC-based activation of the door opening device 10 an improved AC-based activation of the door opening device 10 has also been proposed.
