Aus dem Stand der Technik ist gemäß der
Aus der
Der Erfindung liegt somit die Aufgabe zugrunde, eine Schaltungsanordnung bereitzustellen, die einen energiesparenden Betrieb und eine verbesserte Verfügbarkeit der Gerätefunktion bereitstellt.The invention is therefore based on the object to provide a circuit arrangement which provides an energy-saving operation and improved availability of the device function.
Erfindungsgemäß wird diese Aufgabe durch eine Schaltungsanordnung mit den Merkmalen des unabhängigen Anspruchs 1 gelöst. Vorteilhafte Ausgestaltungen und Weiterbildungen der Erfindung ergeben sich aus den nachfolgenden abhängigen Ansprüchen.According to the invention, this object is achieved by a circuit arrangement having the features of independent claim 1. Advantageous embodiments and modifications of the invention will become apparent from the following dependent claims.
Der mit der Erfindung erreichte Vorteil besteht darin, dass auch im abgeschalteten Zustand, also wenn das Schaltnetzteil vom Versorgungsnetz getrennt ist, ein Einschalten des Gerätes durch Gerätezustände oder eine Bedingung einer Bedienhandhabe möglich ist. Ferner ist sowohl ein zuverlässiges Abschalten und Wiedereinschalten des Haushaltgerätes nach einer Unterbrechung des Versorgungsnetzes möglich.The advantage achieved by the invention is that even in the off state, so when the switching power supply is disconnected from the power supply, switching on the device by device states or a condition of an operating handle is possible. Furthermore, both a reliable shutdown and reconnection of the household appliance after an interruption of the supply network is possible.
Gemäß der Erfindung umfasst die Schaltungsanordnung als elektrischen Schalter ein bistabiles Relais mit einer ersten Spule zum Schließen des Schalters und einer zweiten Spule zum Öffnen des Schalters, wobei die erste Spule und die zweite Spule zumindest mittelbar mit dem Steuerungsmittel verbunden ist und dass der Taster zwischen zumindest einer Leitung des Versorgungsnetzes und dem Schaltnetzteil angeordnet ist, um beim Schließen des Tasters die direkte Verbindung des Versorgungsnetzes mit dem Schaltnetzteil zu bewirken und das Steuerungsmittel zu aktivieren. Ein bistabiles Relais als Schalter zu verwenden hat den Vorteil, dass nur kurzzeitige Stromimpulse benötigt werden, um den Kontakt von dem getrennten Zustand in den verbundenen Zustand zu bewegen oder umgekehrt. Ferner ist sichergestellt, dass bei einer Unterbrechung des Versorgungsnetzes oder einem Stromausfall das Gerät eingeschaltet bleibt, wenn das Versorgungsnetz wieder Strom liefert. Ferner wird erreicht, dass bei betätigtem Netztaster das Schaltnetzteil unmittelbar mit dem Versorgungsnetz verbunden ist und darüber primärseitig versorgt wird, sodass innerhalb weniger Millisekunden das Steuermittel zur Erfassung des Tasterzustandes aktiviert wird. In dieser Anlaufphase, während der Taster noch gedrückt wird, erkennt das Steuermittel, dass das Gerät eingeschaltet werden soll und gibt nun seinerseits einen Stromimpuls auf die Relaisspule, die das Schließen des elektrischen Schalters bewirkt. Nach dieser Anlaufphase kann der Taster deaktiviert werden, da der elektrische Schalter sich in einen mechanisch stabilen Zustand befindet und dabei die Verbindung des Versorgungsnetzes zu den elektrischen Verbrauchern im Gerät hergestellt hat. Bei erneuter Betätigung des Tasters erkennt das Steuermittel, dass ein eingeschaltetes Gerät ausgeschaltet werden soll. Das Steuermittel aktiviert nun die Relaisspule, die das Öffnen des elektrischen Schalters bewirkt.According to the invention, the circuit arrangement comprises as electrical switch a bistable relay having a first coil for closing the switch and a second coil for opening the switch, wherein the first coil and the second coil is at least indirectly connected to the control means and that the switch between at least a line of the supply network and the switching power supply is arranged to effect when closing the button, the direct connection of the supply network with the switching power supply and to activate the control means. Using a bistable relay as a switch has the advantage that only momentary current pulses are needed to move the contact from the disconnected state to the connected state, or vice versa. Furthermore, it is ensured that in the event of an interruption of the supply network or a power failure, the device remains switched on when the supply network supplies power again. It is also achieved that when the power button is pressed, the switching power supply is connected directly to the power supply and is supplied on the primary side, so that within a few milliseconds the control means is activated to detect the button state. In this start-up phase, while the button is still pressed, the control means detects that the device is to be turned on and now in turn gives a current pulse to the relay coil, which causes the closing of the electrical switch. After this start-up phase, the button can be deactivated because the electrical switch is in a mechanically stable state and has made the connection of the supply network to the electrical loads in the device. When the button is pressed again, the control means detects that a switched-on device is to be switched off. The control means now activates the relay coil, which causes the opening of the electrical switch.
In einer zweckmäßigen Ausführung sind die erste Spule und die zweite Spule des bistabilen Relais direkt an das Steuerungsmittel angeschlossen bzw. mit diesem über Verbindungsleitungen verbunden. Hierbei ist das Steuerungsmittel dazu ausgebildet, die Energie der jeweils zu aktivierenden Spule zuzuführen.In an expedient embodiment, the first coil and the second coil of the bistable relay are connected directly to the control means or connected thereto via connecting lines. Here, the control means is adapted to supply the energy of each coil to be activated.
In einer alternativen Ausführung sind die erste Spule und die zweite Spule oder unter Zwischenschaltung jeweils einer Treiberstufe an das Steuerungsmittel angeschlossen. Hierbei kann das Steuerungsmittel als Mikrokontroller ausgeführt sein, der beispielsweise mit 5V oder weniger betrieben wird, wobei die Treiber dazu ausgebildet sind, bei einer Aktivierung durch eine Ansteuerung durch das Steuerungsmittel an der jeweiligen Relaisspule eine höhere Spannung, beispielsweise 24V oder sogar die Versorgungsspannung 230V, anzulegen.In an alternative embodiment, the first coil and the second coil or with the interposition of a respective driver stage are connected to the control means. In this case, the control means may be embodied as a microcontroller, which is operated, for example, with 5V or less, wherein the drivers are designed, upon activation by activation by the control means at the respective relay coil, a higher voltage, for example 24V or even the supply voltage 230V, to apply.
In einer zweckmäßigen Weiterbildung sind die Treiberstufen mit der Versorgungsgleichspannung für ihre Energieversorgung verbunden und die Relaisspulen für den Betrieb mit der Versorgungsgleichspannung geeignet. Hierbei dienen die Treiberstufen dazu, den zum Schalten notwendigen Stromimpuls der Spule zuzuführen.In an expedient development, the driver stages are connected to the DC supply voltage for their energy supply and the relay coils suitable for operation with the DC supply voltage. Here, the driver stages are used to supply the necessary for switching current pulse of the coil.
Das Steuerungsmittel ist dazu eingerichtet, den Schaltzustand des Tasters zu erkennen und aufgrund des erkannten Schaltzustandes und des jeweiligen Zustandes des elektrischen Schalters die erste oder zweite Spule (8a, 8b) zum Öffnen oder schließen des Schalters zu aktivieren.The control means is adapted to detect the switching state of the button and to activate the first or second coil (8a, 8b) for opening or closing the switch due to the detected switching state and the respective state of the electrical switch.
In einer insgesamt vorteilhaften Weiterbildung ist das Steuerungsmittel dazu eingerichtet, den Schaltzustand des Tasters zu erkennen und aufgrund des erkannten Schaltzustandes und des jeweiligen Zustandes des elektrischen Schalters die erste oder zweite Spule zum Öffnen oder Schließen des Schalters zu aktivieren. Dadurch kann nach einer Unterbrechung des Versorgungsnetzes ein selbständiger Wiederanlauf durch das Steuermittel bereitgestellt werden, wenn der Taster vor einer Netzunterbrechung nicht betätigt wurde.In an overall advantageous development, the control means is adapted to recognize the switching state of the button and to activate the first or second coil to open or close the switch due to the detected switching state and the respective state of the electrical switch. As a result, after an interruption of the supply network, an independent restart can be provided by the control means, if the button was not operated before a power failure.
Insgesamt ist es zweckmäßig, ein Erfassungsmittel zum Erfassen des Schaltzustandes des Tasters einzusetzen, das mit dem Steuerungsmittel in Wirkverbindung steht, um den Schaltzustand des Tasters zu erkennen. Damit kann das Erfassungsmittel sehr fein auf das Verhalten und die Eigenschaften des Tasters, Schalters oder Touch-Bedienmittel abgestimmt werden.Overall, it is expedient to use a detection means for detecting the switching state of the button, which is in operative connection with the control means to detect the switching state of the button. Thus, the detection means can be fine tuned to the behavior and properties of the button, switch or touch control.
In einer anderen Weiterbildung umfasst die Schaltungsanordnung eine Steuerungseinrichtung, die zum Steuern von Prozessen im Haushaltgerät ausgebildet ist, die ferner das Steuerungsmittel zum Betätigen des elektrischen Schalters umfasst. Damit kann eine Abschaltung des Gerätes in Abhängigkeit des Gerätes oder Programmzustandes vorgenommen werden, beispielsweise wenn der Benutzer einen Wäschetrockner mittels der Bedienhandhabe abschaltet, kann die Steuereinrichtung ein kontrolliertes Herunterfahren bewirken, so dass in diesem Fall zuerst das Heizregister abgeschaltet wird, wobei das Gebläse und die Trommelbewegung noch eine gewisse Zeit aktiviert sind, bis der gesamte Prozess abgekühlt ist. Die endgültige Trennung des Schaltnetzteils erfolgt somit zeitverzögert.In another development, the circuit arrangement comprises a control device, which is designed to control processes in the household appliance, which further comprises the control means for actuating the electrical switch. Thus, a shutdown of the device depending on the device or program state can be made, for example, when the user turns off a tumble dryer by means of the operating handle, the controller can cause a controlled shutdown, so that in this case, first, the heater is turned off, the fan and the Drum movement is still activated for a certain amount of time until the entire process has cooled down. The final separation of the switching power supply is thus delayed.
In einer weiteren Ausführung ist das Steuerungsmittel zur Auswertung und Erkennung eines Türkontaktes ausgebildet. Damit kann das Öffnen oder Schließen einer Tür, die mit dem Haushaltgerät in funktionellem Zusammenhang steht, zum Ein- oder Ausschalten des Gerätes bzw. zum Verbinden bzw. zum Trennen des Schaltnetzteils zum/vom Versorgungsnetz verwendet werden.In a further embodiment, the control means for the evaluation and detection of a door contact is formed. This can be used to turn on or off the device or for connecting or disconnecting the switching power supply to / from the supply network, the opening or closing of a door that is functionally related to the household appliance.

Die Betätigung des Tasters 6 bewirkt, dass das Erfassungsmittel 5 ein Signal an das Steuerungsmittel 4 überträgt, das dann die Spule 8b zum Abschalten des elektrischen Schalters 3 aktiviert, indem ein festgelegter Stromimpuls der Spule 8b zugeführt wird.To turn off the device, the button 6 is actuated, wherein the
In einer zweckmäßigen Ausführung ist das Steuerungsmittel 4 in der Steuerungseinrichtung 4a, die zum Steuern von Prozessen im Haushaltgerät vorgesehen ist, integriert.
