Abstract

The locking device is constructed as a locking casing (29), moving longitudinally in the direction of the catch (6). Onto its inner walls locking projections (33, 38, 43) are formed. These prevent lever (5) and catch pivoting. The locking device can be moved from a neutral position (I) in which it releases the lever and catch, into a first locking position (II) in which lever pivoting is prevented, and into a second locking position (III) in which pivoting of lever and catch are prevented.

Description

Die Erfindung betrifft eine Türverriegelung für elektrische Geräte, insbesondere für Waschmaschinen, mit einem an der Tür befestigten Kloben, mit einem federgespannten Drehglied, das in einer ersten Drehstellung den Kloben in der Schließstellung der Tür hält und in einer zweiten Drehstellung den Kloben zum Öffnen der Tür freigibt, mit einer schwenkbaren Klinke, mit der das Drehglied in der ersten Drehstellung arretierbar ist, wobei das Drehglied drehbar auf einem schwenkbaren Hebel gelagert ist, der zusammen mit dem Drehglied gegen eine Federkraft derart verschwenkbar ist, dass die Klinke sich relativ zum Drehglied bewegt und dieses für eine Drehung in die zweite Drehstellung freigibt und mit einer Sperrvorrichtung mit Mitteln mit welchen die Schwenkbewegung der Klinke verhinderbar ist.The invention relates to a door lock for electrical devices, in particular for washing machines, with a block fastened to the door, with a spring-loaded rotary member which holds the block in the closed position of the door in a first rotational position and the block for opening the door in a second rotational position releases, with a pivotable pawl, with which the rotary member can be locked in the first rotational position, the rotary member being rotatably mounted on a pivotable lever which, together with the rotary member, can be pivoted against a spring force such that the pawl moves relative to the rotary member and this releases for rotation into the second rotational position and with a locking device with means with which the pivoting movement of the pawl can be prevented.

Aus der DE 39 19 458 C2 ist eine Türverriegelung bekannt, die insbesondere für Wäschetrockner geeignet ist. Dabei sind auf dem Drehglied mehrere Kulissenbahnen angeordnet, die durch ihre Form und den Umstand, dass die Klinke sowohl in axialer als auch in radialer Richtung schwenkbeweglich gelagert ist und in beiden Bewegungsrichtungen unter Federspannung steht, eine Öffnung der Tür auf drei verschiedene Arten zulassen.

  • 1. Elektromagnetische Türöffnung:
    • Ein Elektromagnet, der beispielsweise über eine Türöffnungstaste bestromt werden kann, bewegt die Klinke in eine Außereingriffsstellung, so dass diese eine Bewegung des Drehglieds in die zweite Drehstellung und damit eine Freigabe des Klobens ermöglicht.
  • 2. Öffnung durch Überhub:
    • Durch nochmaliges Drücken der bereits geschlossenen Tür in Schließrichtung dreht der Kloben das Drehglied in eine Drehstellung, in der eine seitliche Bewegung der unter Federspannung stehenden Klinke ermöglicht wird. Hierdurch wird die Verrastung des Drehglieds mit der Klinke aufgehoben und es bewegt sich ebenfalls in die zweite Drehstellung.
  • 3. Öffnen durch Druck von innen:
    • Das Drehglied ist auf einem schwenkbaren Hebel gelagert. Dieser kann zusammen mit dem Drehglied gegen eine Federkraft derart verschwenkt werden, dass das Drehglied sich relativ zur Klinke bewegt und so für eine Drehung in die zweite Drehstellung freigegeben wird. Die Kraft wird durch Druck auf die Innenseite der Tür auf den Kloben und von dort über das Drehglied auf den Hebel aufgebracht. Diese Öffnungsfunktion dient als Notentriegelung. Sie soll es ermöglichen, sich ohne Hilfe bei geschlossener Tür aus dem Inneren der Trommel zu befreien.
From DE 39 19 458 C2 a door lock is known which is particularly suitable for tumble dryers. Several sliding tracks are arranged on the rotary link.Thanks to their shape and the fact that the pawl is pivotally mounted in both the axial and radial directions and is spring-loaded in both directions of movement, the door can be opened in three different ways.
  • 1. Electromagnetic door opening:
    • An electromagnet, which can be energized, for example, via a door opening button, moves the pawl into a disengaged position, so that it enables the rotary member to move into the second rotary position and thus release the clapper.
  • 2. Opening by overstroke:
    • By pressing the already closed door again in the closing direction, the block rotates the rotary member into a rotary position in which a lateral movement of the spring-loaded latch is made possible. As a result, the locking of the rotary member with the pawl is released and it also moves into the second rotary position.
  • 3. Opening by pressure from the inside:
    • The rotating member is mounted on a pivotable lever. This can be pivoted together with the rotary member against a spring force in such a way that the rotary member moves relative to the pawl and is thus released for rotation into the second rotary position. The force is applied by pressing the inside of the door on the block and from there via the rotary link to the lever. This opening function serves as an emergency release. It should make it possible to get out of the inside of the drum without help when the door is closed.

Die vorgenannten Öffnungsfunktionen sind, wie bereits eingangs erwähnt, für einen Haushalts-Wäschetrockner konzipiert. Insbesondere bei Waschmaschinen mit großem Trommelvolumen kann der Wunsch bestehen, diese oder ähnliche Möglichkeiten der Türöffnung ebenfalls anzubieten. Dabei ist jedoch zusätzlich zu beachten, dass es im Verlauf eines Waschprogramms zu Betriebszuständen kommen kann, in denen eine Öffnung der Tür gefährlich ist und deshalb verhindert werden muss. Dies ist beispielsweise der Fall, wenn der Laugenbehälter mit heißer Waschflotte gefüllt ist oder wenn die Trommel im Schleudergang mit einer hohen Drehzahl rotiert.As already mentioned at the beginning, the aforementioned opening functions are designed for a household clothes dryer. Particularly in washing machines with a large drum volume, there may be a desire to also offer these or similar possibilities for opening the door. However, it should also be noted that operating conditions can occur during a washing program in which opening the door is dangerous and must therefore be prevented. This is the case, for example, when the tub is filled with hot wash liquor or when the drum rotates at high speed in the spin cycle.

Aus der DE 196 01 230 A1 ist deshalb eine Türverriegelung bekannt, bei der die Klinke mit einer Öffnung versehen ist, in die der Verriegelungsstift eines Spermechanismus' eintauchen kann. Hierdurch ist zwar die Öffnung durch Überhub und die Öffnung durch einen Elektromagneten sperrbar, aber nicht die Notentriegelung. Der Verriegelungsstift ist nämlich nicht in der Lage, den Schwenkweg des gegen die Federkraft eines Hebels, wie er aus der DE 39 19 458 C2 bekannt ist und auch in der DE 196 01 230 A1 als mögliche Alternative vorgeschlagen wird, zu hemmen. Deshalb lässt sich die Notentriegelung auch während der Durchführung eines Waschprogramms vornehmen, was nicht gewünscht ist.A door lock is therefore known from DE 196 01 230 A1, in which the latch is provided with an opening into which the locking pin of a locking mechanism can be inserted. As a result, the opening can be blocked by overstroke and the opening by an electromagnet, but not the emergency release. The locking pin is in fact unable to inhibit the pivoting path of the lever against the spring force, as is known from DE 39 19 458 C2 and also proposed in DE 196 01 230 A1 as a possible alternative. Therefore, the emergency release can also be carried out while a washing program is being carried out, which is not desired.

Aus der EP 1 217 117 A1 ist eine Vorrichtung zum Sperren und Freigeben eines Türschlosses eines elektrischen Gerätes bekannt. Diese Vorrichtung besitzt einen Schieber mit einer Sperrfläche, die die Drehung einer Greifeinrichtung verhindert und damit die Freigabe eines an der Tür angeordneten Klobens unterbindet. Der Schieber wird durch einen elektrisch gesteuerten Aktuator (Motor, Elektromagnet, piezostriktives Bauteil) bewegt, so dass über die Gerätesteuerung eine zustandsabhängige Sperrung des Türschlosses vorgenommen werden kann. Der Schieber wird über einen relativ aufwändigen Hebelmechanismus bewegt, außerdem ist bei dem dargestellten Türschloss weder eine Öffnung durch Überhub noch ein Öffnen durch Druck von innen möglich.A device for locking and unlocking a door lock of an electrical device is known from EP 1 217 117 A1. This device has a slide with a locking surface, which prevents the rotation of a gripping device and thus prevents the release of a block arranged on the door. The slide is moved by an electrically controlled actuator (motor, electromagnet, piezostrictive component) so that the device lock can be used to lock the door lock depending on the condition. The slide is moved via a relatively complex lever mechanism, and in the door lock shown, neither an opening by overtravel nor an opening by pressure from the inside is possible.

Aus der DE 196 01 228 ist eine Vorrichtung zum Verriegeln der Tür einer Wasch- oder Geschirrspülmaschine bekannt. Bei dieser Vorrichtung greift ein Türhaken oder ein Schließkloben in einen Verriegelungskörper ein und wird durch diesen in der Schließstellung gehalten. Der Verriegelungskörper ist in der Schließstellung durch einen Sperrriegel arretierbar, wobei letzterer durch einen bistabil gelagerten Hebel in seine Arretierstellung bewegt wird. Auch bei dieser Vorrichtung werden sehr viele mechanisch ineinandergreifende Einzelbauteile verwendet, welche sowohl aufgrund der Teilekosten als auch wegen ihrer komplizierten Montage sehr teuer sind. Außerdem besitzt auch diese Verriegelung nicht die Öffnungsmöglichkeiten durch Überhub oder Druck von innen.A device for locking the door of a washing machine or dishwasher is known from DE 196 01 228. In this device, a door hook or a locking block engages in a locking body and is held by this in the closed position. The locking body can be locked in the closed position by a locking bolt, the latter being moved into its locking position by a bistably mounted lever. This device also uses a large number of mechanically interlocking individual components, which are very expensive both because of the part costs and because of their complicated assembly. In addition, this lock also does not have the opening options due to overstroke or pressure from the inside.

Der Erfindung stellt sich somit das Problem, eine Türverriegelung für elektrische Geräte der eingangs genannten Art dahingehend weiterzubilden, dass ihre Öffnungsfunktionen auf einfache und kostengünstige Art durch die Gerätesteuerung gesperrt werden können.The invention therefore presents the problem of developing a door lock for electrical devices of the type mentioned at the outset in such a way that their opening functions can be blocked in a simple and inexpensive manner by the device control.

Erfindungsgemäß wird dieses Problem durch eine Türverriegelung mit den Merkmalen des Patentanspruchs 1 gelöst. Vorteilhafte Ausgestaltungen und Weiterbildungen der Erfindung ergeben sich aus den nachfolgenden Unteransprüchen.According to the invention, this problem is solved by a door lock with the features of claim 1. Advantageous refinements and developments of the invention result from the following subclaims.

Die mit der Erfindung erreichbaren Vorteile bestehen in dem einfachen Aufbau der Sperrvorrichtung, bei der nur ein einziges bewegliches Teil verwendet wird, und in der Tatsache, dass zahlreiche Öffnungsmöglichkeiten für die Gerätetür realisiert werden können und dass diese über den erfindungsgemäßen Sperrmechanismus durch eine einfache lineare Bewegung sperrbar sind.The advantages which can be achieved with the invention consist in the simple construction of the locking device, in which only a single movable part is used, and in the fact that numerous opening possibilities can be realized for the appliance door and that these can be achieved by means of the locking mechanism according to the invention by a simple linear movement are lockable.

In einer vorteilhaften Ausführungsform ist die Sperrvorrichtung derart ausgebildet, dass sie bei ihrer Bewegung in eine Öffnungsstellung die Klinke derart schwenkt, dass sie sich relativ zum Drehglied bewegt und dieses für eine Drehung in die zweite Drehstellung freigibt. Hierdurch wird die Funktionalität der Sperrvorrichtung um eine Öffnungsfunktion erweitert und ein separater Elektromagnet zur Bewegung der Klinke kann eingespart werden.In an advantageous embodiment, the locking device is designed such that when it moves into an open position it pivots the pawl in such a way that it moves relative to the rotary member and releases it for rotation into the second rotary position. As a result, the functionality of the locking device is expanded by an opening function and a separate electromagnet for moving the pawl can be saved.

Es ist auch vorteilhaft, wenn die Klinke und ihre Lagerung und/oder das Drehglied derart ausgebildet sind, dass sie in der Position, die sie einnehmen, wenn sich das Drehglied in der zweiten Drehstellung befindet, die Bewegung der Sperrvorrichtung von der neutralen Stellung in eine andere Stellung sperren. Hierdurch kann entweder über den Motorstrom des Antriebs für die Sperrvorrichtung oder durch einen Positionssensor (Anspruch 7) auf einfache Weise und ohne zusätzlichen Schalter sensiert werden, ob die Tür geschlossen wurde. In einer zweckmäßigen Ausführungsform ist an das Drehglied ein Arretiervorsprung angeformt, der die Bewegung der Sperrvorrichtung von der neutralen Stellung in eine andere Stellung sperrt, wenn sich das Drehglied in der zweiten Drehstellung befindet.It is also advantageous if the pawl and its mounting and / or the rotary member are designed such that in the position which they assume when the rotary member is in the second rotary position, the movement of the locking device from the neutral position into one lock other position. As a result, it can be sensed either via the motor current of the drive for the locking device or by a position sensor (claim 7) in a simple manner and without an additional switch whether the door has been closed. In an expedient embodiment, a locking projection is formed on the rotary member, which blocks the movement of the locking device from the neutral position into another position when the rotary member is in the second rotary position.

In einer weiteren zweckmäßigen Ausführungsform ist die Sperrvorrichtung als in Längsrichtung der Klinke bewegbares Sperrgehäuse ausgebildet, an dessen Innenwände mindestens eine Sperrnase angeformt ist.In a further expedient embodiment, the locking device is designed as a locking housing which can be moved in the longitudinal direction of the pawl and on the inner walls of which at least one locking lug is formed.

Es ist auch vorteilhaft, wenn ein Piezomotor zur Bewegung der Sperrvorrichtung verwendet wird. Ein solcher Motor ist preisgünstig und kompakt im Aufbau.It is also advantageous if a piezomotor is used to move the locking device. Such an engine is inexpensive and compact in construction.

In einer bevorzugten Ausführungsform besitzt die Türverriegelung einen in Richtung der Klinke beweglich gelagerten Auslösestift, mit dem die Klinke in eine Stellung überführbar ist, in der sie eine Drehung des Drehglieds in die zweite Drehstellung freigibt. Hierdurch kann auf einfache Weise eine zusätzliche Öffnungsmöglichkeit realisiert werden, beispielsweise durch einen Hebelmechanismus an der Tür.In a preferred embodiment, the door lock has a release pin movably mounted in the direction of the pawl, with which the pawl can be moved into a position in which it releases a rotation of the rotary member into the second rotary position. This allows for easy An additional opening possibility can be realized, for example by a lever mechanism on the door.

Zunächst werden nachfolgend die einzelnen Bauteile der Türverriegelung erläutert, im Anschluss daran ihre Funktion. Die in den Figuren 1 bis 3 dargestellte Türverriegelung ist in einem Gehäuse angeordnet, von dem in den Zeichnungen lediglich das Unterteil (1) dargestellt ist. Das Gehäuse wiederum ist an einer ebenfalls nicht dargestellten Waschmaschinenfrontseite befestigt. Ein Schließkloben (2) ist mit der Tür (nicht dargestellt) verbunden und greift bei geschlossener Tür durch eine Öffnung (3) im Gehäuseunterteil (1) in den Bereich der Verriegelung ein. Die Türverriegelung weist ein Drehglied (4) auf, welches auf einem Hebel (5) drehbar gelagert ist. Mit dem Drehglied (4) wirkt eine Klinke (6) zusammen, die ebenfalls drehbar auf dem Hebel (5) gelagert ist. Die Lagerstelle (7) der Klinke (6) ist so beschaffen, dass letztere in zwei Richtungen schwenken kann, nämlich zum einen in Figur 1 nach oben und unten und zum anderen in Figur 2 nach oben und unten. Die beiden Schwenkrichtungen stehen somit senkrecht zueinander. Die Klinke (6) ist als flaches einstückiges Blechteil ausgebildet und besitzt annähernd die Form eines Tropfens. Ihre Spitze ist zum Drehglied (4) gerichtet und als Nase (8) nach unten gebogen. Die Klinke (6) wird durch eine am Hebel (5) befestigte Zugfeder (9) einerseits auf das Drehglied (4) und andererseits in Figur 2 nach unten gezogen. Weiterhin besitzt die Türverriegelung eine Justierschraube (10), die von einem an dem Gehäuseunterteil (1) angeformten Dom (11) aufgenommen wird. Der Dom (11) wird von einer Feder (12) umgeben, die sich auf der einen Seite am Hebel (5) und auf der anderen Seite am Gehäuseunterteil (1) abstützt. Durch Drehung der Justierschraube (10), deren Kopf (13) auf den Hebel (5) wirkt, wird die Feder (12) mehr oder weniger gespannt.First, the individual components of the door lock are explained below, followed by their function. The door lock shown in Figures 1 to 3 is in one Arranged housing, of which only the lower part (1) is shown in the drawings. The housing in turn is attached to a washing machine front, also not shown. A locking block (2) is connected to the door (not shown) and, when the door is closed, engages in the area of the lock through an opening (3) in the lower housing part (1). The door lock has a rotary member (4) which is rotatably mounted on a lever (5). A pawl (6) interacts with the rotary member (4) and is also rotatably mounted on the lever (5). The bearing point (7) of the pawl (6) is such that the latter can pivot in two directions, namely on the one hand up and down in FIG. 1 and on the other hand up and down in FIG. 2. The two swivel directions are thus perpendicular to each other. The pawl (6) is designed as a flat, one-piece sheet metal part and has approximately the shape of a drop. Its tip is directed towards the rotary member (4) and bent downwards as a nose (8). The pawl (6) is pulled by a tension spring (9) attached to the lever (5) on the one hand onto the rotary member (4) and on the other hand in FIG. 2 downwards. The door lock also has an adjusting screw (10) which is received by a dome (11) formed on the lower housing part (1). The dome (11) is surrounded by a spring (12) which is supported on one side on the lever (5) and on the other side on the lower housing part (1). By turning the adjusting screw (10), the head (13) of which acts on the lever (5), the spring (12) is more or less tensioned.

Das Drehglied (4) ist durch eine Drehfeder (nicht dargestellt) gegen den Uhrzeigersinn vorgespannt. Es dreht sich insgesamt um eine Achse (15), die in Bezug auf den Hebel (5) ortsfest ist. Am äußeren Umfang des Drehglieds (4) sind Kulissenbahnen (16, 18) angeordnet. An eine Kulissenbahn (16) ist ein nach außen gerichteter Arretiervorsprung (17) angeformt, der nach oben zeigt, wenn sich das Drehglied (4) in der zweiten Drehstellung befindet (s. Figur 8).The rotary member (4) is biased counterclockwise by a torsion spring (not shown). Overall, it rotates around an axis (15) which is stationary with respect to the lever (5). Slide tracks (16, 18) are arranged on the outer circumference of the rotary member (4). An outwardly directed locking projection (17) is molded onto a slide track (16) and points upwards when the rotary member (4) is in the second rotary position (see FIG. 8).

Weiterhin weist die Türverriegelung einen Auslösestift (20) auf, der in einer am Gehäuseunterteil (1) angeformten Hülse (21) in axialer Richtung beweglich gelagert ist. Der Stift (20) wirkt mit einem in der Zeichnung nicht dargestellten, an der Tür angeordneten Hebelgriff zusammen und kann durch dessen Betätigung in Richtung der Klinke (6) gedrückt werden.Furthermore, the door lock has a release pin (20) which is mounted so that it can move in the axial direction in a sleeve (21) formed on the lower housing part (1). The pin (20) interacts with a lever handle (not shown in the drawing) arranged on the door and can be pressed in the direction of the pawl (6) by its actuation.

Der Kloben (2) wirkt mit dem Drehglied (4) in der Weise zusammen, dass er beim Schließen der Tür in eine Ausnehmung (22) eingreift und das Drehglied (4) weiter in eine erste Drehstellung bewegt, in der eine Nase (23) unter den Kloben (2) fährt, so dass er sich nicht in seine Längsrichtung bewegen kann und die Tür verschlossen bleibt. Außerdem wirkt auf das Drehglied (4) die Klinke (6), und zwar über die nach unten gebogene Nase (8), welche sich durch die Spannung der Zugfeder (9) je nach dem Zustand der Türverriegelung auf verschiedenen Kulissenbahnen (16, 18) am Umfang des Drehglieds (4) bewegt. Da die Wirkungsweise der Kulissenbahnen (16, 18) auf die Nase (8) in Abhängigkeit von den verschiedenen Öffnungsbetätigungen bereits aus der DE 39 19 458 C2 bekannt ist, wird darauf nicht näher eingegangen. In dem in den Figuren 1 bis 7 gezeigten Zustand liegt eine Verriegelungskante (19) unter der Wirkung der gegen den Uhrzeigersinn gerichteten Drehfeder an der Verriegelungskante (19) an und hält das Drehglied (4) in der ersten Drehstellung.The block (2) interacts with the rotary member (4) in such a way that when the door is closed it engages in a recess (22) and moves the rotary member (4) further into a first rotary position in which a nose (23) moves under the block (2) so that it cannot move in its longitudinal direction and the door remains locked. In addition, the pawl (6) acts on the rotary member (4), specifically via the downwardly bent nose (8), which is caused by the tension of the tension spring (9) depending on the state of the door lock on different slide tracks (16, 18) moved on the circumference of the rotary member (4). Since the mode of action of the slide tracks (16, 18) on the nose (8) depending on the various opening operations is already known from DE 39 19 458 C2, this will not be discussed in more detail. In the state shown in FIGS. 1 to 7, a locking edge (19) bears against the locking edge (19) under the action of the counterclockwise torsion spring and holds the rotary member (4) in the first rotational position.

Das Gehäuseunterteil (1) besitzt eine zur Waschmaschinenfrontseite gerichtete Grundplatte (24), von der sich senkrecht und nach innen versetzt ein umlaufender Rahmen (25) erstreckt. An den Rahmen (25) sind mit Abstand zur Grundplatte (24) Führungsnasen (26) angeformt, die mit dem Rand (27) der Grundplatte (24) und den Nasen (26) eine Parallelführung (28) erzeugen. In der Führung (28) gleitet ein Sperrgehäuse (29), welches aus einem u-förmig Körper aus Kunststoff gebildet ist. Hierzu sind die unteren Ränder (31) der beiden Schenkel (30) einwärts gebogenen. An die hinteren Ränder (32) der Schenkel (30) sind nach innen gebogene Fortsätze angeformt, die als erste Sperrnasen (33) fungieren. Deren oberer Rand (34) erstreckt sich in einer Höhe, die geringfügig unter dem unterem Rand (36) der Längsseiten (35) des Hebels (5) liegt. An den vorderen Bereich des Stegs (37) des Sperrgehäuses (29) sind eine zweite Sperrnase (38) und eine dritte Sperrnase (43) angeformt, die sich vom Steg (37) aus nach unten erstrecken und durch Bewegung des Sperrgehäuses (29) in den Schwenkbereich der Klinke (6) gefahren werden können. Die Länge der Schenkel (30) ist derart bemessen, dass die dritte Sperrnase (43) gegen den Arretiervorsprung (17) stößt, wenn sich das Drehglied (4) in der zweiten Drehstellung befindet.The lower housing part (1) has a base plate (24) facing the front of the washing machine, from which a circumferential frame (25) extends vertically and offset inwards. Guide lugs (26) are formed on the frame (25) at a distance from the base plate (24) and produce a parallel guide (28) with the edge (27) of the base plate (24) and the lugs (26). A locking housing (29) slides in the guide (28) and is formed from a U-shaped body made of plastic. For this purpose, the lower edges (31) of the two legs (30) are bent inwards. At the rear edges (32) of the legs (30) are formed inwardly bent extensions, which act as the first locking lugs (33). The upper edge (34) extends at a height which is slightly below the lower edge (36) of the longitudinal sides (35) of the lever (5). A second locking lug (38) and a third locking lug (43) are integrally formed on the front area of the web (37) of the locking housing (29), which extend downwards from the web (37) and by moving the locking housing (29) in the swivel range of the pawl (6) can be driven. The length of the legs (30) is dimensioned such that the third locking lug (43) abuts the locking projection (17) when the rotary member (4) is in the second rotary position.

Das Sperrgehäuse (29) wird durch einen Piezomotor (39) in die in Figur 2 mit I bis IV bezeichneten Stellungen bewegt. Alternativ kann ein in den Zeichnungen nicht dargestellter Gleichstrommotor verwendet werden. Zur Sensierung der Stellungen sind auf einer mit der Grundplatte (24) verbundenen Leiterkarte (40) zwei parallele Kontaktbahnen (nicht dargestellt) angeordnet, von denen die eine durchgehend ausgeführt ist und über den oberen Port (40a) von der Waschmaschinensteuerung an Spannung gelegt ist. Die andere Kontaktbahn besitzt Unterbrechungen und ist so in einzelne Kontaktabschnitte unterteilt, die mit verschiedenen Ports (40b, c) auf der Leitekarte verbunden sind. Durch eine Kontaktzunge (41) am Sperrgehäuse (29) werden in Abhängigkeit von seiner Position verschiedene Kontaktabschnitte mit der durchgehenden Kontaktbahn verbunden und so an Spannung gelegt, so dass die Waschmaschinensteuerung (nicht dargestellt) über die Spannungsbelegung der mit den Kontaktabschnitten (40) verbundenen Ports (40b, c) eine Positionserkennung durchführen kann.The locking housing (29) is moved by a piezomotor (39) into the positions designated I to IV in FIG. Alternatively, a DC motor, not shown in the drawings, can be used. To sense the positions, two parallel contact tracks (not shown) are arranged on a printed circuit board (40) connected to the base plate (24), one of which is continuous and is supplied with voltage by the washing machine control system via the upper port (40a). The other contact path has interruptions and is thus divided into individual contact sections which are connected to different ports (40b, c) on the guide card. A contact tongue (41) on the blocking housing (29) connects various contact sections to the continuous contact track depending on its position and thus applies voltage, so that the washing machine control system (not shown) uses the voltage assignment of the ports connected to the contact sections (40) (40b, c) can perform position detection.

Im folgenden sind die Funktionen der Türverriegelung beschrieben:The functions of the door lock are described below:

Bei einer Notentriegelung wird die Tür in Figur 1 nach unten gedrückt. Dabei zieht der an ihr befestigte Kloben (2) über die Nase (23) das Drehglied (4) nach unten. Zunächst ist das Drehglied (4) noch in der Schließstellung mittels der Nase (8) der Klinke (6) verriegelt. Wird nun das gesamte System bestehend aus Drehglied (4), Hebel (5) und Klinke (6) gegen die Kraft der Feder (12) weiter nach unten gezogen, so überwindet nach einem Teil der synchronen Schwenkbewegung von Hebel (5) und Klinke (6) letztere einen Leerhub und stößt dann gegen den oberen Rand der Hülse (21). Dabei hebt die Nase (8) der Klinke (6) vom Drehglied (4) ab und gibt es frei. Die Drehfeder bewegt das Drehglied (4) in die zweite Drehstellung, in der der Kloben (2) freigegeben wird.In the event of an emergency release, the door in FIG. 1 is pressed down. The clamp (2) attached to it pulls the rotary member (4) down over the nose (23). First, the rotary member (4) is still locked in the closed position by means of the nose (8) of the pawl (6). If the entire system consisting of rotary member (4), lever (5) and pawl (6) is pulled further down against the force of the spring (12), then overcomes part of the synchronous one Pivotal movement of lever (5) and pawl (6) the latter an idle stroke and then abuts against the upper edge of the sleeve (21). The nose (8) of the pawl (6) lifts off the rotary member (4) and releases it. The torsion spring moves the rotary member (4) into the second rotational position, in which the block (2) is released.

Bei einer Entriegelung über den Hebelgriff wird der Auslösestift (20) in der Hülse (21) in Richtung der Klinke (6) bewegt und drückt diese vom Drehglied (4) weg. Dabei wird die Nase (8) der Klinke (6) über die Verriegelungskante (19) angehoben und damit das Drehglied (4) freigegeben. Die Drehfeder bewegt dann das Drehglied (4) in die zweite Drehstellung, in der der Kloben (2) freigegeben wird.When unlocking via the lever handle, the release pin (20) in the sleeve (21) is moved in the direction of the pawl (6) and presses it away from the rotary member (4). The nose (8) of the pawl (6) is raised above the locking edge (19) and the rotary member (4) is thus released. The torsion spring then moves the rotary member (4) into the second rotational position, in which the block (2) is released.

Die Öffnung durch Überhub, also durch nochmaliges Drücken der bereits geschlossenen Tür in Schließrichtung, bewirkt eine geringe Drehung des Drehglieds (4) im Uhrzeigersinn durch den Kloben (2). Dabei entfernt sich die Verriegelungskante (19) von der Nase (8) der Klinke (6), und die von der Drehfeder erzeugte Reibungskraft zwischen Nase (8) und Verriegelungskante (19) wird aufgehoben. Dies wiederum ermöglicht eine seitliche Bewegung der Klinke (6) auf eine andere Kulissenbahn (16), die keine Verriegelungskante (19) besitzt. Somit gerät die Klinke (6) in eine Außereingriffsstellung und das Drehglied (4) vollführt gegen den Uhrzeigersinn eine Drehung in die zweite Drehstellung, in der es den Kloben (2) freigibt.The opening by overstroke, i.e. by pressing the already closed door again in the closing direction, causes the rotary member (4) to turn slightly clockwise through the block (2). The locking edge (19) moves away from the nose (8) of the pawl (6) and the frictional force generated by the torsion spring between the nose (8) and the locking edge (19) is canceled. This in turn enables the pawl (6) to move laterally onto another slide track (16) which has no locking edge (19). Thus, the pawl (6) is in an disengaged position and the rotary member (4) rotates counterclockwise to the second rotary position, in which it releases the block (2).

Die vorbeschriebenen Öffnungsfunktionen können von der Waschmaschinensteuerung durch Stromzufuhr zum Piezomotor (39) und einer damit verbundenen Bewegung des Sperrgehäuses (29) deaktiviert werden.The above-described opening functions can be deactivated by the washing machine control system by supplying power to the piezomotor (39) and a movement of the locking housing (29) associated therewith.

Die Figuren 1 bis 3 zeigen das Sperrgehäuse (29) in einer sogenannten neutralen Stellung (I), in welcher es sich in den Figuren 1 und 2 in der äußersten linken Position befindet. Hier sind alle Sperrnasen in Außereingriffsstellung, so dass alle drei vorbeschriebenen Öffnungsvarianten möglich sind. Diese Stellung (I) nimmt das Sperrgehäuse (29) nach dem Programmende ein.Figures 1 to 3 show the locking housing (29) in a so-called neutral position (I), in which it is in the extreme left position in Figures 1 and 2. Here, all locking lugs are in the disengaged position, so that all three opening variants described above are possible. This position (I) takes the lock housing (29) after the end of the program.

In den Figuren 4 und 5 hat der Piezomotor (39) das Sperrgehäuse (29) nach rechts in eine erste Verriegelungsstellung (II) bewegt. Diese Bewegung ist nur möglich, wenn sich das Drehglied (4) in der ersten Drehstellung befindet, d. h., die Tür muss geschlossen sein und der Kloben (2) vom Drehglied (4) fixiert werden. Ansonsten zeigt der Arretiervorsprung (17) nach oben und die dritte Sperrnase (43) fährt dagegen. Hierdurch wird eine Weiterbewegung des Sperrgehäuses (29) verhindert. Die ausbleibende Bewegung kann die Waschmaschinensteuerung daran erkennen, dass trotz eingeschaltetem Piezomotor (39) die Kontaktabschnitte (40) nicht an Spannung gelegt werden (bei Verwendung eines Gleichstrommotors wäre hier eine zusätzliche Stromsensierung mit Abschaltung notwendig, um den Motor nicht zu überlasten). Hierdurch kann ein Betrieb der Waschmaschine bei geöffneter Tür verhindert werden. In der in den Figuren 4 und 5 gezeigten Position, d. h., bei erfolgreicher Bewegung des Sperrgehäuses (29) in die erste Verriegelungsstellung (II), liegen die ersten Sperrnasen (33) jeweils unter dem unterem Rand (36) der Längsseiten (35) des Hebels (5). Hierdurch wird ein Schwenken des Hebels (5) gegen die Kraft der Feder (12) verhindert und damit die Notentriegelung gesperrt. Eine solche Sperrung ist nach dem Start eines Waschprogramms sinnvoll, um zu verhindern, dass bei überladener Trommel die Wäsche die Tür selbsttätig aufdrückt. Ein Öffnen der Tür durch Überhub und/oder durch Betätigung des Hebelgriffs kann in diesem Programmabschnitt noch zugelassen werden, da die Waschflotte noch nicht stark erhitzt ist und die Trommel nur mit Waschdrehzahl bewegt wird. Dem Benutzer wird so ermöglicht, Wäsche nachzulegen.In FIGS. 4 and 5, the piezomotor (39) has moved the locking housing (29) to the right into a first locking position (II). This movement is only possible when the rotary member (4) is in the first rotary position, ie the door must be closed and the block (2) fixed by the rotary member (4). Otherwise, the locking projection (17) points upwards and the third locking lug (43) moves against it. This prevents further movement of the locking housing (29). The washing machine control system can recognize the lack of movement by the fact that, despite the piezo motor (39) being switched on, the contact sections (40) are not energized (if a DC motor were used, an additional current sensor with shutdown would be necessary in order not to overload the motor). This can prevent the washing machine from operating when the door is open. In the position shown in FIGS. 4 and 5, ie when the locking housing has been moved successfully (29) in the first locking position (II), the first locking lugs (33) are each below the lower edge (36) of the longitudinal sides (35) of the lever (5). This prevents the lever (5) from pivoting against the force of the spring (12) and thus locks the emergency release. Such a lock is useful after starting a washing program to prevent the laundry from opening the door automatically when the drum is overloaded. Opening the door by overstroke and / or by actuating the lever handle can still be permitted in this program section, since the washing liquor is not yet very hot and the drum is only moved at the washing speed. This enables the user to add laundry.

Die Figuren 6 und 7 zeigen das Sperrgehäuse (29) in einer zweiten Verriegelungsstellung (III). In dieser Position sperren die ersten Sperrnasen (33) weiterhin die Schwenkbewegung des Hebels (5) und damit die Notentriegelung. Die zweite Sperrnase (38) befindet sich neben der Klinke (6) und verhindert deren seitliche Schwenkbewegung auf die andere Kulissenbahn (16), die keine Verriegelungskante (19) besitzt. Hierdurch wird auch die Öffnungsmöglichkeit durch Überhub gesperrt. Gleichzeitig liegt der Steg (37) des Sperrgehäuses (29) über der Klinke (6) und blockiert eine Schwenkbewegung, die die Nase (8) senkrecht von der Verriegelungskante (19) abheben würde (verursacht durch den Auslösestift 20). Somit ist auch eine Öffnung durch den Hebelgriff gesperrt.Figures 6 and 7 show the locking housing (29) in a second locking position (III). In this position, the first locking lugs (33) continue to block the pivoting movement of the lever (5) and thus the emergency release. The second locking lug (38) is located next to the pawl (6) and prevents its lateral pivoting movement onto the other slide track (16), which has no locking edge (19). This also blocks the possibility of opening due to overstroke. At the same time, the web (37) of the locking housing (29) lies above the pawl (6) and blocks a pivoting movement which would raise the nose (8) vertically from the locking edge (19) (caused by the release pin 20). Thus, an opening is blocked by the lever handle.

Die Waschmaschinensteuerung bewegt das Sperrgehäuse (29) in diese zweite Verriegelungsstellung (III), wenn dem Benutzer jegliche Öffnung der Tür untersagt werden soll, was beispielsweise bei stark erhitzter Waschflotte oder bei schneller Drehung der Trommel geboten ist.The washing machine control moves the locking housing (29) into this second locking position (III) if the user is to be prohibited from opening the door, which is necessary, for example, when the washing liquor is very hot or when the drum rotates quickly.

Die Figuren 8 und 9 zeigen eine zusätzliche Öffnungsmöglichkeit der Türverriegelung. Hier hat der Piezomotor (39) das Sperrgehäuse (29) über seine zweite Verriegelungsstellung (III) hinaus in eine Öffnungsstellung (IV) gefahren. In dieser Stellung (IV) wird die zweite Sperrnase (38) in den verbreiterten Bereich (42) der Klinke (6) bewegt, bis sie ihren Rand berührt und bei weiterer Bewegung in Figur 9 die Klinke (6) nach oben schwenkt. Dadurch wird die Nase (8) seitlich aus ihrer Position hinter der Verriegelungskante (19) gedrückt und gibt das Drehglied (4) frei. Die Drehfeder bewegt dann das Drehglied (4) in die zweite Drehstellung, in der der Kloben (2) nicht mehr arretiert ist. Durch die vorbeschriebene Wirkungsweise wird bei eingeschalteter Stromversorgung eine Öffnung der Tür über einen elektrischen Taster ermöglicht.Figures 8 and 9 show an additional possibility of opening the door lock. Here the piezomotor (39) has moved the blocking housing (29) beyond its second locking position (III) into an open position (IV). In this position (IV), the second locking lug (38) is moved into the widened area (42) of the pawl (6) until it touches its edge and the pawl (6) swivels upward in FIG. As a result, the nose (8) is pressed laterally out of its position behind the locking edge (19) and releases the rotary member (4). The torsion spring then moves the rotary member (4) into the second rotational position, in which the block (2) is no longer locked. The above-described mode of operation enables the door to be opened using an electrical button when the power supply is switched on.
