The locking pin is first transferred to the transfer to the closed position in an intermediate position in which the locking bolt locks with the lock latch, and in the further transfer to the closed position, the door is moved by the latch bolt locked with the lock bolt in the direction of the body. In this way, the dense concerns of the door on the surrounding the treatment room front frame or arranged on this seal is improved. In this case, an electric drive to an electric motor and a driven by the electric motor spindle, which carries at the door facing the end of an external thread and designed as a hook closing clamp with a arranged on the hook arm designed as a fastening arm internal thread in the longitudinal direction of the spindle movable on the external thread is held and engages with the locking arm formed as a hook arm in the closed position in the lock latch.

Zwar ist aus der DE 197 05 821 C1 eine TĆ¼rverriegelung bekannt, bei der das freie Ende des SchlieƟklobens keilfƶrmig ausgebildet ist. Hierdurch soll jedoch ein anderes Ziel erreicht werden, nƤmlich die Mƶglichkeit zu schaffen, dass der Benutzer bei bereits betƤtigter TĆ¼rverriegelung auch eine noch offenstehende TĆ¼r schlieƟen kann, ohne dabei die TĆ¼rverriegelung wieder in die Ɩffnungslage Ć¼berfĆ¼hren zu mĆ¼ssen. Zum anderen ist diese AusfĆ¼hrungsform nicht dazu geeignet, das erfindungsgemƤƟe Problem zu lƶsen. Bei der AusfĆ¼hrungsform gemƤƟ der DE 197 05 821 C1 verlƤuft die den Keil bildende SchrƤgflƤche derart, dass die TĆ¼r bei einem Kontakt der SchrƤgflƤche des SchlieƟklobens mit der SchrƤgflƤche der Schlossfalle in Richtung der Ɩffnungslage gedrĆ¼ckt wĆ¼rde. Dies ist das genaue Gegenteil von dem, was durch die erfindungsgemƤƟe Anordnung erreicht wird, nƤmlich dass die TĆ¼r bei der weiteren ƜberfĆ¼hrung in die SchlieƟlage durch den mit der Schlossfalle verriegelten SchlieƟkloben weiter in Richtung des Korpus bewegt wird.Although is out of the DE 197 05 821 C1 a door lock is known in which the free end of the locking pin is wedge-shaped. As a result, however, another goal is to be achieved, namely to create the possibility that the user can also close a still open door while already activated door lock, without having to convert the door lock again in the open position. On the other hand, this embodiment is not suitable for solving the problem according to the invention. In the embodiment according to the DE 197 05 821 C1 runs the wedge-forming inclined surface such that the door would be pressed in a contact of the inclined surface of the locking bolt with the inclined surface of the latch in the direction of the opening position. This is the exact opposite of what is achieved by the arrangement according to the invention, namely that the door is moved further in the direction of the body during the further transfer to the closed position by the locking bolt locked with the lock latch.

Eine besonders vorteilhafte Weiterbildung sieht vor, dass der SchlieƟkloben in der Ɩffnungslage vollstƤndig in dem als GehƤuse ausgebildeten Korpusteil aufgenommen ist. Auf diese Weise ist das optische Erscheinungsbild der Frontseite und damit der optische Gesamteindruck des HaushaltsgerƤts weiter verbessert.A particularly advantageous further development provides that the locking block in the open position is completely accommodated in the body part designed as a housing. To this Way, the visual appearance of the front and thus the overall visual impression of the household appliance is further improved.

Eine weitere vorteilhafte Weiterbildung sieht vor, dass der SchlieƟkloben in AbhƤngigkeit des Vorliegens eines vorher festgelegten Schaltzustands in einer Auswerteschaltung einer elektrischen Steuerung des HaushaltsgerƤts durch einen elektrischen Antrieb zwischen der Ɩffnungslage und der SchlieƟlage hin und her bewegbar ist. Hierdurch ist der Benutzerkomfort verbessert und eine weitergehende Automatisierung der TĆ¼rverriegelung und der davon abhƤngigen Betriebsprogramme des HaushaltsgerƤts ermƶglicht.A further advantageous development provides that the locking pin is movable in response to the presence of a predetermined switching state in an evaluation circuit of an electrical control of the household appliance by an electric drive between the open position and the closed position back and forth. As a result, the user comfort is improved and a more extensive automation of the door lock and the dependent operating programs of the household appliance allows.

Eine vorteilhafte Weiterbildung der vorgenannten AusfĆ¼hrungsform sieht vor, dass der SchlieƟkloben in dessen Ɩffnungslage und SchlieƟlage jeweils einen Ausschalter zum Ausschalten des elektrischen Antriebs betƤtigt. Hierdurch ist das Ausschalten des elektrischen Antriebs auf besonders einfache Weise verwirklicht.An advantageous development of the aforementioned embodiment provides that the locking block in its open position and closed position each actuates a switch for switching off the electric drive. As a result, the switching off of the electric drive is realized in a particularly simple manner.

ZweckmƤƟigerweise verlƤuft die Bewegung des Verriegelungsarms des Hakens zwischen der Ɩffnungs- und der Zwischenlage im Wesentlichen parallel zu einer durch die geschlossene TĆ¼r aufgespannte Ebene.Conveniently, the movement of the locking arm of the hook between the opening and the intermediate layer is substantially parallel to a plane spanned by the closed door plane.

Eine besonders vorteilhafte Weiterbildung der vorgenannten AusfĆ¼hrungsform sieht vor, dass die Schlossfalle einen Anschlag fĆ¼r den Haken aufweist, an dem der Haken in der Zwischenlage anliegt, wobei der Haken allein in dieser Lage in eine parallel zur LƤngsrichtung der Spindel verlaufende LƤngsfĆ¼hrung des Korpusteils einfahrbar ist. Auf diese Weise ist gewƤhrleistet, dass die TĆ¼r bei dem nachfolgenden Betrieb des HaushaltsgerƤts in gewĆ¼nschter Weise an dem Frontrahmen des Korpus dicht anliegt. DarĆ¼ber hinaus ist hierdurch eine ungewĆ¼nschte Lage der TĆ¼r relativ zum Korpus auf einfache Weise automatisch erkennbar.A particularly advantageous development of the aforementioned embodiment provides that the latch has a stop for the hook against which the hook rests in the intermediate layer, wherein the hook alone in this position in a direction parallel to the longitudinal direction of the spindle longitudinal guide of the body part is retractable. In this way it is ensured that the door in the subsequent operation of the household appliance in the desired manner to the front frame of the carcass tight. In addition, this is an undesirable position of the door relative to the body in a simple manner automatically recognizable.

Eine vorteilhafte Weiterbildung der vorgenannten AusfĆ¼hrungsform sieht vor, dass der Elektromotor als ein Synchronmotor ausgebildet ist. Hierdurch ist es auf einfache Weise ermƶglicht, dass der durch den Elektromotor bewegte SchlieƟkloben bei einer nicht korrekt platzierten TĆ¼r automatisch zurĆ¼ck in die Ɩffnungslage Ć¼berfĆ¼hrt wird.An advantageous development of the aforementioned embodiment provides that the electric motor is designed as a synchronous motor. This makes it possible in a simple manner that the closing cam moved by the electric motor is automatically transferred to an incorrectly placed door back to the open position.

Eine andere vorteilhafte Weiterbildung sieht vor, dass die Spindel mittels einer an dem Korpusteil angeordneten NotausrĆ¼ckungsvorrichtung von dem Elektromotor entkoppelbar ist. Auf diese Weise ist gewƤhrleistet, dass die TĆ¼r bei einer Fehlfunktion oder Blockade des elektrischen Antriebs manuell geƶffnet werden kann.Another advantageous embodiment provides that the spindle can be decoupled from the electric motor by means of an emergency release device arranged on the body part. In this way, it is ensured that the door can be opened manually in case of malfunction or blockage of the electric drive.

Fig. 1 zeigt ein als Einbaubackofen mit Pyrolysefunktion ausgebildetes HaushaltsgerƤt mit einer erfindungsgemƤƟen TĆ¼rverriegelung. Das HaushaltsgerƤt weist einen Korpus 2 und einen durch eine TĆ¼r 4 verschlieƟbaren Behandlungsraum 1 auf. Der Behandlungsraum 1 ist vorne durch einen umlaufenden Frontrahmen 5 umgeben. Zwischen dem Ć¼brigen Korpus 2 und dem Frontrahmen 5 ist eine umlaufende TĆ¼rdichtung 5.1 angeordnet, an der die TĆ¼r 4 in deren geschlossenen Zustand dicht anliegt. Die TĆ¼r 4 ist in Fig. 1 in der SchlieƟlage dargestellt, so dass die TĆ¼rdichtung 5.1 nicht sichtbar ist. In dem oberen Bereich des Korpus 2 ist ein an sich bekannter Abluftkanal 6 zur Ableitung von KĆ¼hlluft aus dem HaushaltsgerƤt angeordnet, wobei der besseren Ɯbersichtlichkeit wegen der bis auf Luftaustrittsschlitze vorne geschlossene Korpus in diesem Korpusteil 7 nach vorne offen dargestellt ist. In dem darin ausgebildeten Abluftkanal 6 ist ein in den nachfolgenden Fig. nƤher dargestellter SchlieƟkloben 8 mit dessen Verstellmimik angeordnet. Der Korpusteil 7 bildet somit ein GehƤuse fĆ¼r den SchlieƟkloben 8 und dessen Verstellmimik, wobei der SchlieƟkloben 8 in der nicht dargestellten Ɩffnungslage, in der die TĆ¼r 4 nicht verriegelt ist, vollstƤndig in dem als GehƤuse ausgebildeten Korpusteil 7 angeordnet ist. Die Verstellmimik des SchlieƟklobens 8 ist sowohl in der Ɩffnungs- wie auch in der SchlieƟlage des SchlieƟklobens 8 vollstƤndig in dem Korpusteil 7 aufgenommen. Fig. 1 shows a trained as a built-in oven with pyrolysis home appliance with a door lock according to the invention. The household appliance has a body 2 and a lockable by a door 4 treatment room 1. The treatment room 1 is surrounded at the front by a circumferential front frame 5. Between the remaining body 2 and the front frame 5, a circumferential door seal 5.1 is arranged, on which the door 4 tightly in the closed state. The door 4 is in Fig. 1 shown in the closed position, so that the door seal 5.1 is not visible. In the upper region of the body 2, a per se known exhaust duct 6 for discharging cooling air from the domestic appliance is arranged, for better clarity because of up to air outlet slots front closed body in this body part 7 is shown to the front open. In the exhaust duct 6 formed therein, a closer in the following Fig. Shown locking block 8 is arranged with its Verstellmimik. The body part 7 thus forms a housing for the locking bolt 8 and its Verstellmimik, wherein the locking block 8 in the open position, not shown, in which the door 4 is not locked, is arranged completely in the housing part designed as a housing part 7. The Verstellmimik the SchlieƟklobens 8 is completely taken up in the body part 7 both in the opening and in the closed position of the locking bolt 8.

Wie aus der Fig. 1 ersichtlich, Ć¼berragt der Korpus 2 mit dem Korpusteil 7 zumindest teilweise eine RandflƤche 9 der TĆ¼r 4. Durch eine in dem Korpusteil 7 ausgebildete Ɩffnung greift der SchlieƟkloben 8 in der hier dargestellten SchlieƟlage in eine in der RandflƤche 9 der TĆ¼r 4 ausgebildete Ɩffnung, die Schlossfalle 10, ein. In der dargestellten SchlieƟlage der TĆ¼rverriegelung liegt die TĆ¼r 4, wie bereits erlƤutert, dicht an dem Frontrahmen 5 bzw. der TĆ¼rdichtung 5.1 an. Dies wird zum einen durch vorgespannte, nicht dargestellte Federn erreicht, die die ƜberfĆ¼hrung der TĆ¼r 4 in deren SchlieƟlage fƶrdern. Zum anderen unterstĆ¼tzt die erfindungsgemƤƟe TĆ¼rverriegelung in vorteilhafter Weise das dichte Anliegen der TĆ¼r 4 an dem Frontrahmen 5 bzw. der TĆ¼rdichtung 5.1, was nachfolgend noch nƤher erlƤutert wird.Like from the Fig. 1 can be seen, the body 2 with the body part 7 at least partially surmounted by an edge surface 9 of the door 4. By an opening formed in the body part 7 of the locking pin 8 engages in the closed position shown here in a formed in the edge surface 9 of the door 4 opening, the latch 10, one. In the illustrated closed position of the door lock the door 4, as already explained, close to the front frame 5 and the door seal 5.1 on. This is achieved on the one hand by prestressed springs, not shown, which promote the transfer of the door 4 in its closed position. On the other hand, the door lock invention advantageously supports the tight fit of the door 4 on the front frame 5 and the door seal 5.1, which will be explained in more detail below.

In Fig. 2 ist der SchlieƟkloben 8 und dessen Verstellmimik nƤher dargestellt. Auf einer TrƤgerplatte 12 ist ein Elektromotor 14 angeordnet, der Ć¼ber eine Antriebsschnecke 16 auf dem Fachmann bekannte Weise eine Spindel 18 mit einem Zahnrad 20 antreibt. Die Spindel 18 wird nachfolgend anhand der Fig. 4 nƤher erlƤutert. Im vorderen Bereich der Spindel 18, also in dem der TĆ¼r 4 zugewandten Bereich, ist der SchlieƟkloben 8 drehbar gehalten. Die Spindel 18 ist mittels eines als NotausrĆ¼ckungsvorrichtung ausgebildeten Lagers 22 auf der TrƤgerplatte 12 drehbar an der Spindel 18 gehalten. Ɯber GestƤnge 24 und 26 sowie Ć¼ber einen an der Spindel 18 angeordneten Nocken 28 sind zwei Mikroschalter 30 und 32 betƤtigbar. Sobald einer der beiden Mikroschalter 30, 32 betƤtigt wird, wird der als Synchronmotor ausgebildete Elektromotor 14 mittels einer nicht nƤher dargestellten Steuerung 34 und einer darin integrierten Auswerteschaltung 35 ausgeschaltet. Befindet sich der SchlieƟkloben 8 in der in Fig. 1 dargestellten SchlieƟlage betƤtigt die Spindel 18 Ć¼ber den Nocken 28 und das GestƤnge 26 den Mikroschalter 32 und schaltet dadurch den Elektromotor 14 aus. Befindet sich der SchlieƟkloben 8 in der nicht dargestellten Ɩffnungslage betƤtigt die Spindel 18 Ć¼ber den Nocken 28 und das GestƤnge 24 den Mikroschalter 30 und schaltet dadurch den Elektromotor 14 aus. Siehe hierzu auch die Fig. 3.In Fig. 2 is the closing block 8 and its Verstellmimik shown in more detail. On a support plate 12, an electric motor 14 is arranged, which drives a spindle 18 with a gear 20 via a drive screw 16 in a manner known to those skilled in the art. The spindle 18 will be described below with reference to Fig. 4 explained in more detail. In the front region of the spindle 18, that is, in the area facing the door 4, the locking bolt 8 is rotatably held. The spindle 18 is rotatably supported on the spindle 18 on the carrier plate 12 by means of a bearing 22 designed as an emergency release device. About linkage 24 and 26 and a arranged on the spindle 18 cam 28, two micro-switches 30 and 32 can be actuated. As soon as one of the two microswitches 30, 32 is actuated, the electric motor 14 embodied as a synchronous motor is switched off by means of a control 34 (not shown) and an evaluation circuit 35 integrated therein. Is the locking pin 8 in the in Fig. 1 shown closed position, the spindle 18 actuates the microswitch 32 via the cam 28 and the linkage 26 and thereby switches off the electric motor 14. The locking pin 8 is in the open position, not shown, the spindle 18 is actuated via the cam 28 and the linkage 24, the micro-switch 30 and thereby switches off the electric motor 14. See also the Fig. 3 ,

Fig. 3 zeigt die vorgenannten Bauteile des SchlieƟklobens 8 und dessen Verstellmimik im Detail. Der Elektromotor 14 wurde aus GrĆ¼nden der Ɯbersichtlichkeit hier nicht dargestellt. Der SchlieƟkloben 8 ist als ein Haken ausgebildet. Der eine als Befestigungsarm ausgebildete Hakenarm 8.1 dient zur drehbaren Befestigung des SchlieƟklobens 8 an der Spindel 18. Der andere als Verriegelungsarm ausgebildete Hakenarm 8.2 greift in der SchlieƟlage des SchlieƟklobens 8 in die Schlossfalle 10 ein. Fig. 3 shows the aforementioned components of the SchlieƟklobens 8 and its Verstellmimik in detail. The electric motor 14 has not been shown here for reasons of clarity. The locking bolt 8 is formed as a hook. The hook arm 8.1 designed as a fastening arm serves for the rotatable attachment of the locking bolt 8 to the spindle 18. The other hook arm 8.2 designed as a locking arm engages in the lock latch 10 in the closed position of the locking bolt 8.

Der SchlieƟkloben 8 und die Spindel 18 sind in Fig. 4 nƤher dargestellt. In dem vorderen Bereich, also dem der TĆ¼r 4 zugewandten Bereich der Spindel 18 weist diese ein AuƟengewinde 36 auf, das mit einem an dem Befestigungsarm 8.1 des SchlieƟklobens 8 ausgebildeten Innengewinde zusammenwirkt.The locking bolt 8 and the spindle 18 are in Fig. 4 shown in more detail. In the front region, that is to say the region of the spindle 18 facing the door 4, this has an external thread 36 which cooperates with an internal thread formed on the fastening arm 8.1 of the closing bolt 8.

Ferner zeigt Fig. 5 den SchlieƟkloben 8 und dessen Verstellmimik in einer perspektivischen Ansicht von schrƤg unten. Die TrƤgerplatte 12 weist eine zu der Ɩffnung in dem Korpusteil 7 korrespondierend ausgebildete Ɩffnung 38 auf, durch die der an der Spindel 18 drehbar gehaltene SchlieƟkloben 8 in der SchlieƟlage nach unten aus der TrƤgerplatte 12 hinausragt. In der nicht dargestellten Ɩffnungslage wird der Verriegelungsarm 8.2 des SchlieƟklobens 8 in dem links dargestellten Abschnitt 40 der Ɩffnung 38 aufgenommen. In dieser Lage ist die TĆ¼r 4 nicht verriegelt, so dass diese in gewohnter Weise aufgeschwenkt werden kann. Die Ɩffnung 38 weist ferner einen hinteren Abschnitt 42 auf. Der SchlieƟkloben 8 ist nur in der in Fig. 5 dargestellten Lage in den hinteren Abschnitt 42 der Ɩffnung 38 einfahrbar. Ist der SchlieƟkloben 8 um dessen Drehachse, also der LƤngsachse der Spindel 18, in eine der beiden Drehrichtungen aus dieser Lage herausgedreht, ist der SchlieƟkloben 8 nicht in den hinteren Abschnitt 42 einfahrbar.Further shows Fig. 5 the locking block 8 and its Verstellmimik in a perspective view obliquely from below. The carrier plate 12 has an opening 38 corresponding to the opening in the body part 7, through which the locking pin 8, which is rotatably held on the spindle 18, protrudes downwards out of the carrier plate 12 in the closed position. In the open position, not shown, the locking arm 8.2 of the locking bolt 8 is received in the section 40 of the opening 38 shown on the left. In this position, the door is 4 not locked, so that it can be swung open in the usual way. The opening 38 further includes a rear portion 42. The locking block 8 is only in the in Fig. 5 shown position in the rear portion 42 of the opening 38 retractable. If the locking block 8 is rotated out of this position about its axis of rotation, that is to say the longitudinal axis of the spindle 18, in one of the two directions of rotation, the locking block 8 can not be moved into the rear section 42.

Die bereits genannte NotausrĆ¼ckungsvorrichtung 22 ist in Fig. 6 im Detail dargestellt. In der hier nicht dargestellten Normallage der NotausrĆ¼ckungsvorrichtung 22 ist die Spindel 18 durch die NotausrĆ¼ckungsvorrichtung 22 drehbar gelagert. Dabei umschlieƟt die NotausrĆ¼ckungsvorrichtung 22 mit einer Lagerbuchse 44 den hinteren Teil 46 der Spindel 18. Falls die TĆ¼rverriegelung durch eine Fehlfunktion der Steuerung 34 oder des Elektromotors 14 blockiert sein sollte, besteht die Mƶglichkeit, die NotausrĆ¼ckungsvorrichtung 22 manuell in die in Fig. 6 dargestellte Entriegelungslage zu Ć¼berfĆ¼hren. Hierzu fĆ¼hrt der Benutzer beispielsweise einen nicht dargestellten Schraubenzieher von vorne durch eine Ɩffnung 48 in der TrƤgerplatte 12 ein und drĆ¼ckt damit gegen einen BetƤtigungsschenkel 50 der NotausrĆ¼ckungsvorrichtung 22. Hierdurch wird die Schnappverbindung zwischen dem BetƤtigungsschenkel 50 und dem Arretierungspfosten 52 gelƶst, und der BetƤtigungsschenkel 50 kann um eine vertikale Drehachse in der Bildebene nach hinten verdreht werden. Die Spindel 18 wird nicht mehr von der NotausrĆ¼ckungsvorrichtung 22 gehalten und die Verzahnung zwischen dem Zahnrad 20 und der Antriebsschnecke 16 ist aufgehoben. Die Spindel 18 ist nicht mehr durch den Elektromotor 14 blockiert und kann vom Benutzer manuell verdreht werden, um die Verriegelung der TĆ¼r 4 zu lƶsen.The already mentioned emergency release device 22 is in Fig. 6 shown in detail. In the not shown here normal position of the emergency release device 22, the spindle 18 is rotatably supported by the emergency release device 22. In this case, the emergency release device 22 encloses the rear part 46 of the spindle 18 with a bearing bushing 44. If the door lock should be blocked by a malfunction of the control 34 or of the electric motor 14, it is possible to manually move the emergency release device 22 into the in Fig. 6 to transfer shown unlocking position. For this purpose, the user introduces, for example, a screwdriver, not shown, from the front through an opening 48 in the support plate 12 and thus presses against an actuating leg 50 of the emergency release device 22. As a result, the snap connection between the actuating arm 50 and the locking post 52 is released, and the actuating arm 50 can to be rotated around a vertical axis of rotation in the image plane to the rear. The spindle 18 is no longer held by the emergency release device 22 and the toothing between the gear 20 and the drive screw 16 is released. The spindle 18 is no longer blocked by the electric motor 14 and can be manually rotated by the user to release the lock of the door 4.

Alternativ hierzu wƤre es auch mƶglich, den BetƤtigungsschenkel 50 mittels einer Befestigungsschraube an dem Arretierungspfosten 52 zu befestigen und damit die Spindel 18 mittels des als NotausrĆ¼ckungsvorrichtung ausgebildeten Lagers 22 an der TrƤgerplatte 12 drehbar zu halten. Zur manuellen ƜberfĆ¼hrung der NotausrĆ¼ckungsvorrichtung 22 in die oben genannte Entriegelungslage wĆ¼rde nun der Schraubenzieher ebenfalls von vorne durch die Ɩffnung 48 in der TrƤgerplatte 12 zum Lƶsen der Befestigungsschraube eingefĆ¼hrt werden. Durch den gleichzeitigen Druck mit dem Schraubenzieher gegen die Befestigungsschraube und damit gegen den Arretierungspfosten 52 wĆ¼rde sich der BetƤtigungsschenkel 50 in der Bildebene von Fig. 6 nach hinten bewegen, so dass sich die NotausrĆ¼ckungsvorrichtung 22 nach hinten von der Spindel 18 lƶsen wĆ¼rde. Wie in dem vorliegenden AusfĆ¼hrungsbeispiel kƶnnte die NotausrĆ¼ckungsvorrichtung 22 um eine vertikale Drehachse in der Bildebene nach hinten verdreht werden. Der weitere Ablauf ist identisch mit dem des AusfĆ¼hrungsbeispiels.Alternatively, it would also be possible to fix the actuating leg 50 by means of a fastening screw to the locking post 52 and thus to keep the spindle 18 rotatably by means of the bearing 22 designed as emergency release bearing 22 on the support plate. For manual transfer of the emergency release device 22 in the above-mentioned unlocking position, the screwdriver would now also be introduced from the front through the opening 48 in the support plate 12 for releasing the fastening screw. Due to the simultaneous pressure with the screwdriver against the fastening screw and thus against the locking post 52, the actuating arm 50 would be in the image plane of Fig. 6 move backwards, so that the emergency release device 22 would be released from the spindle 18 to the rear. As in the present embodiment, the emergency release device 22 could be rotated backwards about a vertical axis of rotation in the image plane. The further procedure is identical to that of the embodiment.

Nachfolgend wird die Funktionsweise der erfindungsgemƤƟen TĆ¼rverriegelung anhand der Fig. nƤher erlƤutert.The mode of operation of the door lock according to the invention will be explained in more detail below with reference to FIG.

Bei dem hier vorliegenden Backofen handelt es sich um einen Pyrolysebackofen. Die TĆ¼rverriegelung dient dem Schutz des Benutzers, da bei der Pyrolyse sehr hohe Temperaturen in dem als Garraum ausgebildeten Behandlungsraum 1 auftreten. Die TĆ¼r 4 ist geschlossen, so dass diese an dem Frontrahmen 5 bzw. der TĆ¼rdichtung 5.1 anliegt. Sobald der Benutzer die Betriebsart Pyrolyse Ć¼ber nicht dargestellte und mit der Steuerung 34 in SignalĆ¼bertragungsverbindung stehende Eingabemittel auswƤhlt, steuert die Steuerung 34 den Elektromotor 14 an, so dass dieser die Spindel 18 im Gegenuhrzeigersinn dreht. Hierbei wird der SchlieƟkloben 8 mitgedreht und bewegt sich dadurch von der nicht dargestellten Ɩffnungslage, in der dieser sich in dem Abschnitt 40 der Ɩffnung 38 befindet, in der Bildebene von Fig. 2 nach unten in die dargestellte SchlieƟlage. In dieser Lage, der Zwischenlage, greift der SchlieƟkloben 8 in die Schlossfalle 10 der TĆ¼r 4 ein und verriegelt dadurch die TĆ¼r 4. Die Spindel 18 wird durch den Elektromotor 14 weiter im Gegenuhrzeigersinn gedreht. In der vorgenannten Zwischenlage wird der SchlieƟkloben 8 durch einen an der Schlossfalle 10 ausgebildeten Anschlag an dem weiteren Mitdrehen gehindert. Der Anschlag ist dabei als die in der Fig. 1 in der Bildebene rechts dargestellte Seitenwand 10.1 der Schlossfalle 10 ausgebildet. In dieser Lage des SchlieƟklobens 8, der Zwischenlage, ist der SchlieƟkloben 8 relativ zu der Ɩffnung in dem Korpusteil 7 und dem hinteren Abschnitt 42 der Ɩffnung 38 der TrƤgerplatte 12 ausgerichtet, so dass der SchlieƟkloben 8 in den hinteren Abschnitt 42 und damit in die LƤngsfĆ¼hrung des Korpusteils 7 einfahrbar ist.The oven here is a pyrolysis oven. The door lock serves to protect the user, since very high temperatures occur in the pyrolysis in the cooking chamber 1 formed as a cooking space. The door 4 is closed, so that it rests against the front frame 5 or the door seal 5.1. As soon as the user selects the pyrolysis mode via input means not shown and in signal communication with the controller 34, the controller 34 drives the electric motor 14 to rotate the spindle 18 counterclockwise. Here, the locking cam 8 is rotated and thereby moves from the open position, not shown, in which it is located in the portion 40 of the opening 38, in the image plane of Fig. 2 down into the illustrated closed position. In this position, the intermediate position, the locking pin 8 engages in the latch 10 of the door 4 and thereby locks the door 4. The spindle 18 is rotated by the electric motor 14 further counterclockwise. In the aforementioned intermediate position of the locking pin 8 is prevented by a formed on the latch 10 stop on the further co-rotation. The attack is as the in the Fig. 1 formed in the image plane right side wall 10.1 of the latch 10 is formed. In this position of the locking bolt 8, the intermediate layer, the locking bolt 8 is aligned relative to the opening in the body part 7 and the rear portion 42 of the opening 38 of the support plate 12, so that the locking bolt 8 in the rear portion 42 and thus in the longitudinal guide of the body part 7 is retractable.

Da der SchlieƟkloben 8, wie bereits erlƤutert, in der Zwischenlage nicht mehr mit der Spindel 18 mitdreht, wird der SchlieƟkloben 8 Ć¼ber das Gewinde 36 und das an dem Befestigungsarm 8.1 angeordnete Innengewinde in der Bildebene der Fig. 2 nach hinten, also weg von der TĆ¼r 4, bewegt und fƤhrt dabei in den hinteren Abschnitt 42 der Ɩffnung 38 ein. Hierdurch zieht der mit der Schlossfalle 10 verriegelte SchlieƟkloben 8 die bereits an dem Frontrahmen 5 anliegende TĆ¼r 4 weiter an diesen heran, so dass dadurch ein dichtes Anliegen der TĆ¼r 4 an dem Frontrahmen 5 bzw. an der TĆ¼rdichtung 5.1 gewƤhrleistet ist. Sobald der SchlieƟkloben 8 die SchlieƟlage, in der die TĆ¼r 4 in gewĆ¼nschter Weise dicht an dem Frontrahmen 5 bzw. an der TĆ¼rdichtung 5.1 anliegt, erreicht hat, schaltet dieser auf die oben bereits erlƤuterte Weise den Elektromotor 14 aus. Die TĆ¼r 4 ist geschlossen und der Pyrolysevorgang wird automatisch gestartet.Since the locking block 8, as already explained, no longer rotates in the intermediate position with the spindle 18, the locking bolt 8 via the thread 36 and arranged on the mounting arm 8.1 internal thread in the image plane of Fig. 2 to the rear, that is away from the door 4, moves and thereby moves into the rear portion 42 of the opening 38 a. As a result, the locking bolt 8 locked with the latch 10 pulls the door 4, which is already in contact with the front frame 5, further, so that a tight contact of the door 4 with the front frame 5 or with the door seal 5.1 is ensured. As soon as the locking bolt 8 has reached the closed position, in which the door 4 rests in the desired manner close to the front frame 5 or to the door seal 5.1, it switches off the electric motor 14 in the manner already explained above. The door 4 is closed and the pyrolysis process is started automatically.

Sollte die TĆ¼r 4 von dem Benutzer nicht ordnungsgemƤƟ geschlossen worden sein, wĆ¼rde der SchlieƟkloben 8 bei der oben erlƤuterten ƜberfĆ¼hrung von der Ɩffnungslage in die SchlieƟlage durch die TĆ¼r 4 blockiert werden, so dass der SchlieƟkloben 8 nicht in gewĆ¼nschter Weise in die Schlossfalle 10 und damit in die Zwischenlage Ć¼berfĆ¼hrt wĆ¼rde. Hierdurch wĆ¼rde der SchlieƟkloben 8 ebenfalls am Mitdrehen mit der Spindel 18 gehindert, ohne aber in den hinteren Abschnitt 42 der Ɩffnung 38 und damit in die LƤngsfĆ¼hrung der Ɩffnung des Korpusteils 7 einfahren zu kƶnnen. Der SchlieƟkloben 8 wĆ¼rde gegen den Korpus 2 fahren und dessen weitere Bewegung blockiert werden. Aufgrund dieser Blockade wĆ¼rde der als Synchronmotor ausgebildete Elektromotor 14 automatisch die Drehrichtung Ƥndern und den SchlieƟkloben 8 automatisch wieder in die Ɩffnungslage Ć¼berfĆ¼hren, in der der Elektromotor 14 auf die oben genannte Weise ausgeschaltet wĆ¼rde.If the door 4 had not been properly closed by the user, the locking block 8 would be blocked in the above-described transfer from the open position to the closed position by the door 4, so that the locking cam 8 is not in the desired manner in the lock latch 10 and thus would be transferred to the intermediate position. As a result, the locking bolt 8 would also be prevented from turning with the spindle 18, but without being able to retract into the rear portion 42 of the opening 38 and thus into the longitudinal guidance of the opening of the body part 7. The locking bolt 8 would go against the body 2 and its further movement will be blocked. Due to this blockade, the electric motor 14 designed as a synchronous motor would automatically change the direction of rotation and automatically return the closing cam 8 to the open position in which the electric motor 14 would be switched off in the above-mentioned manner.

Die oben genannte erste AusfĆ¼hrungsform bewirkt, dass die TĆ¼rverriegelung bei nicht vollstƤndig geschlossener TĆ¼r 4 bei der ƜberfĆ¼hrung von der Ɩffnungslage in die Zwischenlage von der TĆ¼r 4 blockiert wird, so dass die TĆ¼rverriegelung wieder automatisch in die Ɩffnungslage Ć¼berfĆ¼hrt wird.The above-mentioned first embodiment causes the door lock is blocked when not completely closed door 4 in the transfer of the open position in the intermediate layer of the door 4, so that the door lock is automatically transferred back to the open position.

Um nun auch dem Fall gerecht zu werden, dass die TĆ¼r 4 Ć¼berhaupt nicht geschlossen ist, also beispielsweise noch in der vollstƤndig geƶffneten Lage ist, wie in Fig. 7 dargestellt, ist das GestƤnge 24 bei dem zweiten AusfĆ¼hrungsbeispiel der erfindungsgemƤƟen TĆ¼rverriegelung gemƤƟ Fig. 8 modifiziert. Das GestƤnge 24 weist zusƤtzlich zu den baulichen Merkmalen des ersten AusfĆ¼hrungsbeispiels, nƤmlich einer Welle 24.1, einem BetƤtigungsnocken 24.2 und einer in Fig. 8 nicht nƤher dargestellten Mitnehmerrampe 24.3, einen Detektionshebel 24.4 und eine Sperrklinke 24.5 auf. Ansonsten ist die nachfolgend anhand der Fig. 9 bis 14 nƤher erlƤuterte zweite AusfĆ¼hrungsform in Konstruktion und Funktion gleich dem bereits oben erlƤuterten ersten AusfĆ¼hrungsbeispiel.In order to cope with the case that the door 4 is not closed at all, so for example still in the fully open position, as in Fig. 7 shown, the linkage 24 in the second embodiment of the door lock according to the invention according to Fig. 8 modified. The linkage 24 has, in addition to the structural features of the first embodiment, namely a shaft 24.1, an actuating cam 24.2 and a in Fig. 8 Not shown driving ramp 24.3, a detection lever 24.4 and a pawl 24.5. Otherwise, the following is based on the Fig. 9 to 14 explained in more detail second embodiment in construction and function equal to the already explained above first embodiment.

In den Fig. 9 und 10 ist das GestƤnge 24 in der Einbaulage und in unterschiedlichen Perspektiven zu sehen. Fig. 9 zeigt das GestƤnge 24 in der BetƤtigungsstellung des BetƤtigungsnocken 24.2, also in der Stellung, in der mittels des GestƤnges 24 und des Mikroschalters 30 der hier nicht dargestellte Elektromotor 14 auf die bereits erlƤuterte Weise ausgeschaltet wird. Die TĆ¼rverriegelung befindet sich in der Ɩffnungslage. Es sei angemerkt, dass die an dem zweiten Mikroschalter 32 angeordnete Feder zur automatischen RĆ¼ckstellung des GestƤnges 26 anders als in der in den Fig. 9 und 14 dargestellten Lage in der Einbaulage der TĆ¼rverriegelung analog zu dem ersten AusfĆ¼hrungsbeispiel, siehe Fig. 2, mit dem GestƤnge 26 verhakt ist.In the FIGS. 9 and 10 the linkage 24 can be seen in the installation position and in different perspectives. Fig. 9 shows the linkage 24 in the operating position of the actuating cam 24.2, ie in the position in which by means of the linkage 24 and the microswitch 30 of the electric motor 14, not shown here is turned off in the manner already explained. The door lock is in the open position. It should be noted that the arranged on the second microswitch 32 spring for automatic return of the linkage 26 differently than in the in the Fig. 9 and 14 shown position in the installation position of the door lock analogous to the first embodiment, see Fig. 2 , with the linkage 26 is hooked.

Analog zu dem ersten AusfĆ¼hrungsbeispiel wird durch die Auswahl der Betriebsart Pyrolyse durch den Benutzer der Elektromotor 14 in die bereits erlƤuterte Weise angesteuert. Das GestƤnge 24 wird daraufhin wie bei dem ersten AusfĆ¼hrungsbeispiel freigegeben. Der an der sich drehenden Spindel 18 angeordnete Hakenarm 8.2 des SchlieƟklobens 8 gibt die Mitnehmerrampe 24.3 des GestƤnges 24 frei, so dass eine RĆ¼ckstellfeder 60, siehe die Fig. 12 und 14, das GestƤnge 24 derart automatisch bewegt, dass der Detektionshebel 24.4 sich bezogen auf Fig. 11 in der Bildebene nach unten bewegt. In dem gewĆ¼nschten und in den Fig. 11 und 12 dargestellten Normalfall, in dem die TĆ¼r 4 ordnungsgemƤƟ geschlossen ist, wird die vorgenannte AbwƤrtsbewegung des Detektionshebels 24.4 durch die RandflƤche 9 der TĆ¼r 4 gestoppt, so dass die Sperrklinke 24.5 des GestƤnges 24 in der in Fig. 12 dargestellten Lage verbleibt. In dieser Lage der Sperrklinke 24.5 gelangt diese bei der unter dem ersten AusfĆ¼hrungsbeispiel erlƤuterten Bewegung des SchlieƟklobens 8 in Richtung des Korpus nicht in Eingriff mit dem Befestigungsarm 8.1 des SchlieƟklobens 8. Der weitere Ablauf entspricht dem ersten AusfĆ¼hrungsbeispiel.Analogous to the first exemplary embodiment, the selection of the operating mode pyrolysis by the user activates the electric motor 14 in the manner already explained. The linkage 24 is then released as in the first embodiment. The arranged on the rotating spindle 18 hook arm 8.2 of the locking bolt 8 are the driving ramp 24.3 of the linkage 24 free, so that a return spring 60, see the Fig. 12 and 14 , the linkage 24 moves automatically such that the detection lever 24.4 related to Fig. 11 moved down in the image plane. In the desired and in the FIGS. 11 and 12 illustrated normal case in which the door 4 is properly closed, the aforementioned downward movement of the detection lever 24.4 is stopped by the edge surface 9 of the door 4, so that the pawl 24.5 of the linkage 24 in the in Fig. 12 situation remains. In this position, the pawl 24.5 gets this at the bottom of the first Embodiment explained movement of the locking bolt 8 in the direction of the body is not in engagement with the mounting arm 8.1 of the locking bolt 8. The further sequence corresponds to the first embodiment.

Sollte die TĆ¼r 4 von dem Benutzer noch nicht geschlossen worden sein, also sich beispielsweise in der in Fig. 7 dargestellten Lage befinden, kann sich der Detektionshebel 24.4 und damit das ganze GestƤnge 24 in die gleiche Richtung weiterdrehen. Siehe Fig. 13. Dabei bewegt sich die Sperrklinke 24.5 soweit nach unten, dass der SchlieƟkloben 8 mit dem Befestigungsarm 8.1 bei der ƜberfĆ¼hrung von der Ɩffnungslage in die Zwischenlage gegen die Sperrklinke 24.5 fƤhrt und an dieser zur Anlage kommt. Siehe Fig. 14. HierfĆ¼r weist der Befestigungsarm 8.1 einen Vorsprung 8.1.1 auf. Analog zu dem oben bereits erlƤuterten Fall, dass die TĆ¼r 4 nicht vollstƤndig geschlossen ist und der Verriegelungsarm 8.2 des SchlieƟklobens 8 nicht in den hinteren Abschnitt 42 der Ɩffnung 38 einfahren kann, wird die Bewegung des SchlieƟklobens 8 blockiert, was den als Synchronmotor ausgebildeten Elektromotor 14 automatisch die Drehrichtung Ƥndern lƤsst und den SchlieƟkloben 8 wieder in die Ɩffnungslage Ć¼berfĆ¼hrt, in der der Elektromotor 14 Ć¼ber den BetƤtigungsnocken 24.2 und den Mikroschalter 30 ausgeschaltet wird.If the door 4 has not yet been closed by the user, that is, for example, in the in Fig. 7 Position shown, the detection lever 24.4 and thus the entire rod 24 can continue to rotate in the same direction. Please refer Fig. 13 , In this case, the pawl moves 24.5 far enough down that the locking bolt 8 moves with the mounting arm 8.1 in the transfer of the open position in the intermediate position against the pawl 24.5 and comes to rest on this. Please refer Fig. 14 , For this purpose, the mounting arm 8.1 a projection 8.1.1. Analogous to the case already explained above, that the door 4 is not completely closed and the locking arm 8.2 of the locking bolt 8 can not retract into the rear portion 42 of the opening 38, the movement of the closing bolt 8 is blocked, which constitutes the electric motor 14 designed as a synchronous motor automatically change the direction of rotation and the locking cam 8 again transferred to the open position in which the electric motor 14 is turned off via the actuating cam 24.2 and the micro-switch 30.

Die Ausbildung des GestƤnges 24 gemƤƟ dem zweiten AusfĆ¼hrungsbeispiel bewirkt somit, dass auch bei nicht geschlossener TĆ¼r 4 eine Fehlfunktion wirksam vermieden ist.The formation of the linkage 24 according to the second embodiment thus causes a malfunction is effectively avoided even when the door 4 is not closed.

Sofern der oben bereits erlƤuterte Normalfall vorliegt, ist der weitere Ablauf fĆ¼r beide AusfĆ¼hrungsbeispiele identisch.If the normal case already explained above exists, the further sequence is identical for both exemplary embodiments.

Nach Beendigung des Pyrolysevorgangs wird der Elektromotor 14 erneut von der Steuerung 34 angesteuert und zwar derart, dass sich die Spindel 18 nun im Uhrzeigersinn dreht. Da sich der SchlieƟkloben 8 in dem hinteren Abschnitt 42 der Ɩffnung 38 in der TrƤgerplatte 12 bewegt, kann er sich nicht mit der Spindel 18 mitdrehen, so dass er sich in analoger Weise wie bei der ƜberfĆ¼hrung in die SchlieƟlage nun nach vorne in Richtung auf die TĆ¼r 4 zu bewegt. Mit dem Erreichen der oben erlƤuterten Zwischenlage stĆ¶ĆŸt der SchlieƟkloben 8 mit dessen Vorderseite gegen die TrƤgerplatte 12, so dass sich der SchlieƟkloben 8 nicht weiter nach vorne bewegen kann. Siehe Fig. 5. Sobald der SchlieƟkloben 8 die Zwischenlage wieder erreicht hat, kann er sich wieder mit der Spindel 18 mitdrehen und wird auf diese Weise von der Zwischenlage in die bereits erlƤuterte Ɩffnungslage Ć¼berfĆ¼hrt. Damit dies mƶglich ist, muss die Steigung des AuƟengewindes 36 ausreichend groƟ sein, damit sich der SchlieƟkloben 8 trotz der Reibung zwischen dem SchlieƟkloben 8 und der Halteplatte 12 mit der Spindel 18 mitdreht. Alternativ hierzu wƤre es auch mƶglich, den SchlieƟkloben 8 nicht gegen die Halteplatte 12 fahren zu lassen, sondern die VorwƤrtsbewegung des SchlieƟklobens 8 relativ zu der Spindel 18 durch einen an der Spindel 18 angeordneten Anschlag, beispielsweise einen Splint, einen Sicherungsring oder eine Verpressung, zu stoppen. Bei dieser AusfĆ¼hrungsform wƤre dann eine geringere Steigung des AuƟengewindes 36 ausreichend. Bei Erreichen der Ɩffnungslage betƤtigt der SchlieƟkloben 8, wie bereits erlƤutert, den Mikroschalter 30 und schaltet dadurch den Elektromotor 14 wieder aus. Die TĆ¼r 4 ist nun entriegelt. Der Behandlungsraum kann geƶffnet werden.After completion of the pyrolysis process, the electric motor 14 is controlled again by the controller 34 in such a way that the spindle 18 now rotates clockwise. Since the locking cam 8 moves in the rear portion 42 of the opening 38 in the support plate 12, he can not rotate with the spindle 18 so that he now in an analogous manner as in the transfer to the closed position forward toward the Door 4 to move. With the achievement of the above-explained intermediate layer of the locking block 8 abuts with its front against the support plate 12, so that the locking pin 8 can not move forward. Please refer Fig. 5 , Once the locking pin 8 has reached the intermediate position again, he can turn again with the spindle 18 and is transferred in this way from the intermediate position in the already explained opening position. For this to be possible, the pitch of the external thread 36 must be sufficiently large that the locking block 8 rotates with the spindle 18 despite the friction between the locking bolt 8 and the retaining plate 12. Alternatively, it would also be possible not to let the locking bolt 8 drive against the holding plate 12, but the forward movement of the SchlieƟklobens 8 relative to the spindle 18 by a arranged on the spindle 18 stop, for example, a split pin, a locking ring or a compression to stop. In this embodiment would be then a smaller pitch of the external thread 36 is sufficient. When the opening position is reached, the closing block 8, as already explained, actuates the microswitch 30 and thereby switches off the electric motor 14 again. The door 4 is now unlocked. The treatment room can be opened.

Die erfindungsgemƤƟe TĆ¼rverriegelung ist nicht auf das oben erlƤuterte AusfĆ¼hrungsbeispiel begrenzt. Beispielsweise lƤsst sich die erfindungsgemƤƟe TĆ¼rverriegelung auch bei anderen HaushaltsgerƤten wie Dampfgarer, Herden, Waschmaschinen, WƤschetrockner und GeschirrspĆ¼ler einsetzen. Auch ist der Einsatz nicht auf EinbaugerƤte beschrƤnkt; StandgerƤte kƶnnen ebenfalls mit der erfindungsgemƤƟen TĆ¼rverriegelung ausgestattet werden. Ferner ist es denkbar, anstelle der hier verwendeten Antriebsschnecke andere dem Fachmann bekannte und geeignete Antriebselemente zu verwenden. Beispielsweise wƤren Winkelgetriebe im Allgemeinen und KegelrƤder oder TellerrƤder im Speziellen mƶglich. DarĆ¼ber hinaus sind auch konstruktiv weniger aufwendige AusfĆ¼hrungsformen der TĆ¼rverriegelung denkbar. Beispielsweise kƶnnte der SchlieƟkloben durch einen konstruktiv einfachen Mechanismus von oben nach unten in die Schlossfalle eingefahren und wieder herausgefahren werden. Die weitere Anpressung der TĆ¼r an den Frontrahmen bzw. eine TĆ¼rdichtung kƶnnte dabei durch eine keilfƶrmige Ausbildung des SchlieƟklobens erreicht werden. Auch ist die Anordnung der erfindungsgemƤƟen TĆ¼rverriegelung in weiten geeigneten Grenzen wƤhlbar und nicht auf die des AusfĆ¼hrungsbeispiels beschrƤnkt. Beispielsweise wƤre auch eine seitliche Anordnung der TĆ¼rverriegelung denkbar. Sofern der TĆ¼ranschlag nicht an der unteren Seite der Zugangsƶffnung des Behandlungsraums angeordnet, wƤre darĆ¼ber hinaus auch eine Anordnung der TĆ¼rverriegelung in diesem Bereich mƶglich. Anstelle einer TrƤgerplatte ist es auch denkbar, dass der SchlieƟkloben mit dessen Verstellmimik direkt an dem Korpusteil montiert ist.The door lock according to the invention is not limited to the above-described embodiment. For example, the door lock invention can also be used in other household appliances such as steamer, stoves, washing machines, dryers and dishwashers. Also, the use is not limited to built-in appliances; Floor units can also be equipped with the door lock according to the invention. It is also conceivable, instead of the drive screw used here, to use other drive elements known and suitable to the person skilled in the art. For example, bevel gears in general and bevel gears or ring gears in particular possible. In addition, structurally less expensive embodiments of the door lock are conceivable. For example, the locking bolt could be retracted by a structurally simple mechanism from top to bottom in the lock latch and moved out again. The further contact pressure of the door on the front frame or a door seal could be achieved by a wedge-shaped design of the SchlieƟklobens. Also, the arrangement of the door lock according to the invention can be selected within wide suitable limits and not limited to that of the embodiment. For example, a lateral arrangement of the door lock would be conceivable. If the door stop is not arranged on the lower side of the access opening of the treatment room, an arrangement of the door lock in this area would also be possible beyond. Instead of a support plate, it is also conceivable that the locking block is mounted with its Verstellmimik directly to the body part.

Anordnung der TĆ¼rverriegelung in diesem Bereich mƶglich. Anstelle einer TrƤgerplatte ist es auch denkbar, dass der SchlieƟkloben mit dessen Verstellmimik direkt an dem Korpusteil montiert ist.Arrangement of the door lock in this area possible. Instead of a support plate, it is also conceivable that the locking block is mounted with its Verstellmimik directly to the body part.
