Definitions
- the invention relates to an electromanetic door lock for machines with a rotary latch, which comprises a door-side block, and a pivot lever blocking the rotary latch, which is locked by an electromagnetically actuated rocker.
- Electromagnetic door locks of the type mentioned in the generic term have been used in washing machines, dishwashers, centrifuges and similar devices in which there could be any danger to the operator from the interior. Most of these machines have a large, circumferential seal, so that the rotary latch is exposed to considerable pressure.
- the object of the invention is to provide an inexpensive locking device for low voltage, which is also "finger-safe" according to the VDE guidelines.
- Fig. 1 denotes the housing base plate, in which a main bearing pin 2 for the rotary latch 3, a bearing pin 4 for the pivot lever 5 and a bearing pin 6 for the rocker 7 are attached.
- An electromagnet 8 is connected to the left end of the rocker 7 via its armature 8a.
- query levers 9, 10 are mounted on the bolt 2.
- a spring indicated by the arrow 11 serves to turn these levers clockwise.
- the rotary latch 3 is shown in the closed state. Its claw encompasses the door-side block 12 indicated by dash-dotted lines.
- the lower left end of the rotary latch has a recess 3a which bears against a roller 13. This is mounted on the pivot lever 5 via a pin 14.
- the lever carries a further pin 15 with a smaller roller 16. This roller abuts the right end of the rocker 7, as a result of which the pivot lever 5 and thus also the rotary latch 3 are blocked.
- the electromagnet 8 When the electromagnet 8 is energized, it pulls its armature 8a and thereby moves the rocker 7 clockwise. The right locking edge 7a of the rocker 7 runs down over the roller 16, whereby the blockage of the lever 5 is released is. If a pulling force is now exerted on the rotary latch 3 via the block 12, the projection 3b presses the pivot lever 5 to the left so that the rotary latch can open.
- the query levers 9, 10 pivot upward, as a result of which they block the pivot lever 5 in the position typical for the unlocking.
- Fig. 2 shows the position of all parts with the door open.
- a leg spring 17 ensures that the pivot lever 5 bears against the query levers 9, 10.
- Fig. 3 the complete door lock is shown in plan view.
- a microswitch 19 can be seen, which is fastened with a screw 20.
- This microswitch to be installed from the outside is actuated by a bracket 21 shown in FIGS. 1 and 2, which is connected to the pivot lever 5.
- With 22, 23, 24 through holes are designated, which are used to attach the housing to the door frame.
- a housing opening 25 provides a view of the rotary latch 3 and the query levers 9, 10. Actuating surfaces 9a, 10a are formed on these levers.
- the block 12 is held by two fastening tabs which hit the surfaces 9a, 10a when the door is closed, while at the same time the block 12 presses the catch 3 downwards.
- the query levers 9, 10 release the pivot lever 5 so that it can pivot counterclockwise and can lock the rotary latch 3 via the roller 13.
- the microswitch is only activated when the pivot lever 5 assumes the position shown in FIG. 1. In this position, the lever 5 can then be blocked again by the rocker 7, this rocker being tilted into the blocking position by the force of a weak spring indicated by the arrow 26.
- the query levers on the left and right of the rotary latch have the task of outwitting the door lock to prevent. To lock the rotary latch and to actuate the microswitch, it is not sufficient to push the rotary latch down with the door open. So it should be prevented that the machine - wanted or unwanted - can start with the door open.
- the microswitch is only activated at the moment when the swivel lever has locked the rotary latch. Conversely, the microswitch interrupts when opening before the rotary latch is released.
- the magnetic force required to trigger the rocker 7 is very low because its locking edge 7a can run over the smooth-running roller 16.
- the longitudinal axis AB of the rocker 7 encloses an angle of just over 90 ° with the longitudinal axis CD of the pivoting lever 5. It is thereby achieved that, in the event of a tensile force on the catch 3, the pivot lever 5 remains in the stable dead position despite the forces transmitted to it, because no torque is transmitted to the rocker 7. From this locked position, the release force of the magnet is so low that a low-voltage magnet, e.g. for 12 volts, can be used. This makes it extremely easy to comply with the safety regulations, especially for devices with moisture release.
- an emergency release element 27 shown here as a pulling element, which acts on the rocker 7. It would be even more inconspicuous to make a small hole in the housing on the magnetic side of the rocker 7, through which the initiate can insert a pin.
- the rocker 7 is constructed so that the center of mass coincides with the axis of rotation (bearing pin 6). This prevents the rocker from being knocked out or unwanted from the locked position as a result of blows or imbalances in the centrifuge or centrifuge and the door from opening when the machine is running.
- the electromagnetic door lock described can be used with great gain in operating safety for all devices and machines that have rotating parts or work with dangerous liquids and vapors. These are preferably spin dryers and washing machines and dishwashers, as are used in industry or in the service sector.

Description
Die Erfindung betrifft eine elektromanetische Türverriegelung für Maschinen mit einer Drehfalle, die einen türseitigen Kloben umfaßt, und einem die Drehfalle blockierenden Schwenkhebel, der durch eine elektromagnetisch betätigte Wippe verriegelt ist.The invention relates to an electromanetic door lock for machines with a rotary latch, which comprises a door-side block, and a pivot lever blocking the rotary latch, which is locked by an electromagnetically actuated rocker.
Elektromagnetische Türverriegelungen der im Gattungsbegriff genannten Art sind bei Waschmaschinen, Spülmaschinen, Schleudern und ähnlichen Geräten eingesetzt worden, bei denen vom Innenraum her irgendeine Gefahr auf den Bedienenden ausgehen könnte. Meist weisen diese Maschinen eine großflächige, umlaufende Dichtung auf, so daß die Drehfalle einem erheblichen Druck ausgesetzt ist.Electromagnetic door locks of the type mentioned in the generic term have been used in washing machines, dishwashers, centrifuges and similar devices in which there could be any danger to the operator from the interior. Most of these machines have a large, circumferential seal, so that the rotary latch is exposed to considerable pressure.
Bisher war es üblich, auf die Wippe einen kräftigen Netzspannungsmagneten einwirken zu lassen, um über das Wippenende den die Drehfalle blockierenden Schwenkhebel freizugeben. Da die auf dem Türrahmen montierte Verriegelungseinrichtung Dampf, Feuchtigkeit oder sonstigen aggressiven Medien ausgesetzt sein kann, bedarf es besonderer kostenträchtiger Maßnahmen, um die von der Netzspannung ausgehenden Gefahren zu eliminieren, also die VDE-Bestimmungen zu erfüllen. Weiterhin ist es ein Problem, die Maschinen gegen die Folgen falscher Bedienung abzusichern, insbesondere das Anlaufen bei offener Tür zu verhindern. Es darf also nicht möglich sein, daß der Bedienende lediglich mit einem Werkzeug die Drefalle herunterdrückt, um über den eingebauten Mikroschalter die Maschine bei offener Tür zu starten.So far, it has been common to have a strong mains voltage magnet act on the rocker in order to release the swivel lever blocking the rotary latch via the rocker end. Since the locking device mounted on the door frame can be exposed to steam, moisture or other aggressive media, special cost-intensive measures are required to eliminate the dangers posed by the mains voltage, i.e. to meet the VDE regulations. It is also a problem to protect the machines against the consequences of incorrect operation, in particular to prevent them from starting when the door is open. It should not be possible for the operator to press the latch with just one tool to start the machine with the door open using the built-in microswitch.
Aufgabe der Erfindung ist es, eine preisgünstige Verriegelungseinrichtung für Kleinspannung zu schaffen, die zusätzlich nach den VDE-Richtlinien "fingersicher" ist.The object of the invention is to provide an inexpensive locking device for low voltage, which is also "finger-safe" according to the VDE guidelines.
Diese Aufgabe wird mit den im Patentanspruch 1 angegebenen Mitteln gelöst.This object is achieved with the means specified in
Ein Ausführungsbeispiel der Erfindung wird anhand von Fig. 1 - 3 der Zeichnung erläutert. Einander entsprechende Teile sind mit den gleichen Bezugszeichen versehen.

In Fig. 1 ist mit 1 die Gehäusegrundplatte bezeichnet, in welcher ein Hauptlagerbolzen 2 für die Drehfalle 3, ein Lagerbolzen 4 für den Schwenkhebel 5 und ein Lagerbolzen 6 für die Wippe 7 befestigt sind. Ein Elektromagnet 8 ist über seinen Anker 8a mit dem linken Ende der Wippe 7 verbunden.
Links und rechts der Drehfalle 3 sind Abfragehebel 9, 10 auf dem Bolzen 2 gelagert. Eine mit dem Pfeil 11 angedeutete Feder dient dazu, diese Hebel im Uhrzeigersinn zu verdrehen. Die Drehfalle 3 ist im Schließzustand dargestellt. Ihre Klaue umfaßt den strichpunktiert angedeuteten türseitigen Kloben 12. das linke, untere Ende der Drehfalle weist eine Vertiefung 3a auf, die an einer Rolle 13 anliegt. Diese ist über einen Bolzen 14 auf dem Schwenkhebel 5 gelagert. Der Hebel trägt einen weiteren Bolzen 15 mit einer kleineren Rolle 16. Diese Rolle stößt gegen das rechte Ende der Wippe 7, wodurch der Schwenkhebel 5 und damit auch die Drehfalle 3 blockiert sind.
Wenn der Elektromagnet 8 an Spannung gelegt wird, zieht er seinen Anker 8a an und bewegt dabei die Wippe 7 im Uhrzeigersinn. Die rechte Sperrkante 7a der Wippe 7 läuft über die Rolle 16 nach unten, wodurch die Blockade des Hebels 5 aufgehoben ist. Wenn jetzt über den Kloben 12 auf die Drehfalle 3 eine Zugkraft ausgeübt wird, drückt der Vorsprung 3b den Schwenkhebel 5 nach links, so daß die Drehfalle öffnen kann. Zugleich schwenken die Abfragehebel 9, 10 nach oben, wodurch sie den Schwenkhebel 5 in der für die Entriegelung typischen Position blockieren.In Fig. 1, 1 denotes the housing base plate, in which a main bearing

In Fig. 3 ist die komplette Türverriegelung in der Draufsicht dargestellt. Auf die Grundplatte 1 ist eine fast spiegelbildlich gleiche Gehäusedeckplatte aufgesetzt, die entsprechende Bohrungen zumindest für die Lagerbolzen 2 und 4 aufweist. In einem Teilaufbruch erkennt man einen Mikroschalter 19, der mit einer Schraube 20 befestigt ist. Dieser von außen einzubauende Mikroschalter wird durch einen in Fig. 1 und 2 dargestellten Ausleger 21 betätigt, der mit dem Schwenkhebel 5 verbunden ist. Mit 22, 23, 24 sind Durchgangslöcher bezeichnet, die der Befestigung des Gehäuses an der Türzarge dienen. Eine Gehäuseöffnung 25 gibt den Blick auf die Drehfalle 3 und die Abfragehebel 9, 10 frei. An diese Hebel sind Betätigungsflächen 9a, 10a angeformt. Der Kloben 12 wird von zwei Befestigungslaschen gehalten, die beim Schließen der Tür auf die Flächen 9a, 10a auftreffen, während zugleich der Kloben 12 die Drehfalle 3 nach unten drückt. Die Abfragehebel 9, 10 geben den Schwenkhebel 5 frei, so daß dieser entgegen dem Uhrzeigersinn schwenken und über die Rolle 13 die Drehfalle 3 verriegeln kann.
Der Mikroschalter wird erst dann betätigt, wenn der Schwenkhebel 5 die Position nach Fig. 1 einnimmt. In dieser Lage kann dann der Hebel 5 durch die Wippe 7 erneut blockiert werden, wobei diese Wippe durch die Kraft einer mit dem Pfeil 26 angedeuteten schwachen Feder in die Sperrstellung gekippt wird.
Die links und rechts von der Drehfalle gelagerten Abfragehebel haben die Aufgabe, eine Überlistung des Türverschlusses zu verhindern. Zum Einrasten der Drehfalle und zur Betätigung des Mikroschalters reicht es nicht aus, daß man bei offener Tür die Drehfalle herunterdrückt. Es soll also verhindert werden, daß die Maschine - gewollt oder ungewollt - bei offener Tür anlaufen kann.In Fig. 3 the complete door lock is shown in plan view. On the

The query levers on the left and right of the rotary latch have the task of outwitting the door lock to prevent. To lock the rotary latch and to actuate the microswitch, it is not sufficient to push the rotary latch down with the door open. So it should be prevented that the machine - wanted or unwanted - can start with the door open.
Für die gefahrlose Bedienung der Maschine ist es sehr wichtig, daß der Mikroschalter erst in dem Augenblick betätigt wird, in dem der Schwenkhebel die Drehfalle gesperrt hat. Umgekehrt unterbricht der Mikroschalter beim Öffnen, bevor die Drehfalle freigegeben wird.For the safe operation of the machine it is very important that the microswitch is only activated at the moment when the swivel lever has locked the rotary latch. Conversely, the microswitch interrupts when opening before the rotary latch is released.
Die erforderliche Magnetkraft zur Auslösung der Wippe 7 ist sehr gering, weil ihre Sperrkante 7a über die leichtgängige Rolle 16 ablaufen kann. Für die günstige Kinematik der Hebel ist es wichtig, daß die Längsachse AB der Wippe 7 mit der Längsachse CD des Schwenkhebels 5 einen Winkel von knapp über 90° einschließt. Damit wird erreicht, daß bei einer Zugkraft an der Drehfalle 3 der Schwenkhebel 5 trotz der auf ihn übertragenen Kräfte in der stabilen Totlage verbleibt, weil auf die Wippe 7 kein Drehmoment übertragen wird. Aus dieser Sperrlage heraus ist die Auslösekraft des Magneten so gering, daß ohne weiteres ein Kleinspannungsmagnet, z.B. für 12 Volt, eingesetzt werden kann. Dies erleichtert gerade bei Geräten mit Feuchtigkeitsabgabe außerordentlich die Einhaltung der Sicherheitsvorschriften.The magnetic force required to trigger the
Für den Fall, daß die Steuereinrichtung eine Störung aufweist oder der Elektromagnet versagt, kann man sehr leicht eine Notauslösung realisieren. Es genügt dazu ein Notauslöseelement 27, hier als Zugelement dargestellt, das an der Wippe 7 angreift. Noch unauffälliger wäre es, im Gehäuse auf der Magnetseite der Wippe 7 eine kleine Bohrung anzubringen, durch die der Eingeweihte einen Stift einführen kann.In the event that the control device has a fault or the electromagnet fails, it is very easy to implement an emergency release. All it takes is an
Bei allen Anwendungsfällen mit einer großflächigen Türdichtung ist die Rückfederkraft am Kloben so groß, daß die Drehfalle beim Auslöseimpuls selbsttätig umklappt. Beim Verriegeln der Tür ist dann eine entsprechend hohe Schließkraft aufzubringen.In all applications with a large door seal, the spring-back force on the block is so great that the catch automatically turns over when the trigger is triggered. A correspondingly high closing force must then be applied when the door is locked.
Der entscheidende Vorteil der Erfindung ist aber darin zu sehen, daß unabhängig von den je nach Anwendungsfall unterschiedlichen Schließkräften die Auslösekraft klein und konstant ist.The decisive advantage of the invention, however, can be seen in the fact that it differs depending on the application Closing forces the release force is small and constant.
Um die günstigen mechanischen Eigenschaften auch unter widrigen Umweltbedingungen beizubehalten, werden wichtige Teile wie Federn, Hebel, Bolzen aus Edelstahl hergestellt, während die Gehäusehälften aus Druckguß, vorzugsweise Zinkdruckguß, bestehen.In order to maintain the favorable mechanical properties even under adverse environmental conditions, important parts such as springs, levers, bolts are made of stainless steel, while the housing halves are made of die-cast, preferably zinc die-cast.
Zur Erhöhung der Betriebssicherheit ist die Wippe 7 so aufgebaut, daß der Massenmittelpunkt mit der Drehachse (Lagerbolzen 6) zusammenfällt. Damit wird verhindert, daß sich die Wippe durch Schläge oder Unwuchten in der Zentrifuge bzw. Schleuder gewollt oder ungewollt aus der Sperrstellung herauslöst und die Tür bei laufender Maschine aufspringt.To increase operational safety, the
Die beschriebene elektromagnetische Türverriegelung kann mit großem Zugewinn an Bedienungssicherheit bei allen Geräten und Maschinen eingesetzt werden, die rotierende Teile aufweisen oder mit gefährlichen Flüssigkeiten und Dämpfen arbeiten. Vorzugsweise sind dies Schleudern sowie Wasch- und Spülmaschinen, wie sie in der Industrie oder im Dienstleistungsgewerbe benutzt werden.The electromagnetic door lock described can be used with great gain in operating safety for all devices and machines that have rotating parts or work with dangerous liquids and vapors. These are preferably spin dryers and washing machines and dishwashers, as are used in industry or in the service sector.
