Abstract
Description
Der Gegenstand der Erfindung betrifft ein Haushaltgerät, insbesondere eine Geschirrspülmaschine oder einen Herd mit einem durch eine Gerätetür verschließbaren Spül- oder Backraum mit mindestens einem Geschirrkorb bzw. Gargutträger, wobei die Gerätetür um eine horizontale Schwenkachse klappbar ist.The subject matter of the invention relates to a household appliance, in particular a dishwasher or a stove with a washing or baking space which can be closed by an appliance door and has at least one crockery basket or food support, the appliance door being foldable about a horizontal pivot axis.
Bei Geschirrspülmaschinen oder Herden, die als Einbau- oder Standgeräte in Küchenunterschrankzeilen oder dgl. installiert sind, ist es besonders für körperbehinderte Menschen oder auch für viele ältere Personen schwierig und mühevoll, die geöffnete Gerätetür nach dem Beschicken der Geschirrkörbe oder Gargutträger aus der unteren Stellung nach oben zu schwenken, da man sich hierfür tief bücken muß. Dieses Problem tritt aber auch auf, wenn die Gerätetür zum Herausziehen und Entleeren der Körbe nach einem Spül- oder Backvorgang bis in ihre unterste Türstellung aufgeschwenkt werden muß. Auch hier soll die Erfindung Abhilfe schaffen.In the case of dishwashers or stoves that are installed as built-in or stand-alone units in rows of kitchen cabinets or the like, it is particularly difficult and tedious for physically handicapped people or for many older people to open the appliance door after loading the baskets or food carriers from the lower position to swing up, because you have to bend down deep for this. However, this problem also occurs when the appliance door has to be swung open into its lowest door position in order to pull out and empty the baskets after a rinsing or baking process. The invention is also intended to remedy this.
Ausgehend von einem Haushaltgerät der eingangs genannten Art werden die vorstehenden Probleme erfindungsgemäß gelöst durch die Merkmale des Anspruchs 1.Starting from a household appliance of the type mentioned at the outset, the above problems are solved according to the invention by the features of
Vorteilhafte Weiterbildungen sind den Unteransprüchen zu entnehmen.Advantageous further developments can be found in the subclaims.
Auf diese Weise ergibt sich eine Vielfalt von Vorteilen: Durch das motorgesteuerte und/oder halbautomatische Türschließen bzw. Türöffnen wird der Bedienungskomfort des Haushaltgerätes erheblich gesteigert; sowohl das motorgesteuerte als auch das manuelle Türöffnen und/oder Türschließen kann bequem von der Frontseite des Gerätes her eingeleitet und ausgeführt werden, wobei die Bedienungsperson immer ihre aufrechte Bedienungshaltung beibehalten kann; bei einem nur teilweisen automatischen (halbautomatischen) Türschließvorgang genügt es, wenn die vollständig geöffnete Gerätetür nur bis zu einer Türoffenstellung motorisch geschlossen wird, welche etwa in Handgriffhöhe des Gerätebedieners liegt, von dieser Stellung aus läßt sich die Tür dann manuell ebenfalls in aufrechter Bedienhaltung in Schließstellung bringen; das automatische Türschließen ist von der jeweiligen Geschirrkorb- oder Gargutträgerstellung im Spül- oder Backraum abhängig gemacht, so daß sichergestellt ist, daß z. B. ein herausgezogener Geschirrkorb nicht durch die sich schließende Gerätetür in den Spülraum gestoßen wird und hierdurch Geschirr zu Bruch geht; der elektromotorische Antrieb mit dem nachgeschalteten Verstellgetriebe für die Gerätetür sowie die Steuereinrichtung für den Antrieb sind kontrollierbar auf einer im Bereich des unteren Gerätegehäuses vorzugsweise lösbar angeordneten Trägerplatte prüf- und auswechselbar montiert, wodurch sich eine servicefreundliche Baugruppeneinheit ergibt.This results in a variety of advantages: the ease of use of the household appliance is increased considerably by the motor-controlled and / or semi-automatic door closing or door opening; Both motor-controlled and manual door opening and / or door closing can be conveniently initiated and carried out from the front of the device, the operator always being able to maintain his upright operating position; in the case of an only partially automatic (semi-automatic) door closing process, it is sufficient if the fully open appliance door is only closed by a motor up to a door open position which is approximately at the handle height of the appliance operator, from this position the door can then also be manually operated in an upright operating position bring into the closed position; the automatic door closing is made dependent on the respective crockery basket or food support position in the washing or baking chamber, so that it is ensured that, for. B. a pulled-out crockery basket is not pushed through the closing appliance door into the wash cabinet, causing crockery to break; the electromotive drive with the downstream adjustment gear for the appliance door and the control device for the drive can be inspected and exchangeably mounted on a support plate which is preferably detachably arranged in the area of the lower appliance housing, resulting in a service-friendly assembly unit.
Die nachstehende Beschreibung dient der Erläuterung des Gegenstandes gemäß der Erfindung, von dem ein Ausführungsbeispiel in den Zeichnungen dargestellt ist. Es zeigen:
Figur 1- eine mit Besteck- und Geschirrkörben ausgestattete Geschirrspülmaschine in der Seitenansicht, bei geschlossener Gerätetür,
Figur 2- die Geschirrspülmaschine bei teilweise geöffneter Gerätetür,
Figur 3- die Geschirrspülmaschine bei vollständig geöffneter Gerätetür,
- Figure 1
- a side view of a dishwasher equipped with cutlery and crockery baskets, with the appliance door closed,
- Figure 2
- the dishwasher with the appliance door partially open,
- Figure 3
- the dishwasher with the appliance door fully open,
Die in den Figuren 1 bis 3 gezeigte Geschirrspülmaschine (1) besitzt einen unteren sowie einen mittleren Geschirrkorb (4 bzw. 5) und in einer dritten Spülebene einen zusätzlichen Besteckkorb (6) in Form einer flachen Besteckschublade. Bei teilgeöffneter Gerätetür (2) (Fig. 2) kann zumindest der flache Besteckkorb (6) zum Ablegen von zu spülenden Besteckteilen noch ungehindert herausgezogen werden. Der mittlere Geschirrkorb (5) hingegen ist bei dieser Türstellung nur noch teilweise und der untere Geschirrkorb (4) nicht mehr mit Spülgut beschickbar. Die teilgeöffnete Gerätetür (2) läßt in der gezeigten Stellung in der Regel jedoch noch ein Befüllen des Gerätes mit Reiniger bzw. Klarspüler zu. Hierfür sind die entsprechenden Dosiervorrichtungen (8) zum Befüllen, wie bekannt, in der Gerätetür (2) in einer bedienerfreundlichen Höhe angeordnet.The dishwasher (1) shown in FIGS. 1 to 3 has a lower and a middle crockery basket (4 and 5) and, in a third washing level, an additional cutlery basket (6) in the form of a flat cutlery drawer. With partially open The appliance door (2) (FIG. 2) can at least pull out the flat cutlery basket (6) unhindered for storing cutlery items to be washed. The middle crockery basket (5), on the other hand, can only be partially loaded in this door position and the lower crockery basket (4) can no longer be loaded with dishes. In the position shown, however, the partially open appliance door (2) usually still allows the appliance to be filled with detergent or rinse aid. For this purpose, as is known, the corresponding metering devices (8) for filling are arranged in the appliance door (2) at a user-friendly height.
Zur weiteren Bedienungserleichterung ist gemäß der Erfindung im Gerätegehäuse (9) der Geschirrspülmaschine (1) ein elektromotorischer Antrieb (10) mit zugeordneter Steuereinrichtung (11) und nachgeschaltetem Verstellgetriebe (12) zum ganz oder teilweisen (halbautomatischen) Schließen und/oder Öffnen der Gerätetür (2) untergebracht. Dabei ist der elektromotorische Antrieb mit dem nachgeschalteten Verstellgetriebe (12) im Bereich des unteren Gerätegehäuses (9) vorzugsweise im Scharnierbereich der Gerätetür (2) kontrollierbar angeordnet, wobei das vom Antrieb bewegte Verstellgetriebe (12) mittelbar (Fig. 1 bis 3) oder unmittelbar an der Gerätetür (2) angreift.To further facilitate operation, according to the invention, an electromotive drive (10) with an associated control device (11) and a subsequent adjustment gear (12) for fully or partially (semi-automatic) closing and / or opening the appliance door () in the appliance housing (9) of the dishwasher (1). 2) housed. The electromotive drive with the downstream adjustment gear (12) in the area of the lower device housing (9) is preferably arranged in a controllable manner in the hinge area of the device door (2), the adjustment gear (12) moved by the drive being indirect (Fig. 1 to 3) or directly attacks on the appliance door (2).
Im oberen Gerätebereich ist ein manuell zu bedienender mit der Steuereinrichtung (11) in Wirkverbindung stehender Schalter (Auslöseschalter 13) oder dergl. für die Türbewegungssteuerung vorgesehen. Der Auslöseschalter (13) kann an der Geräteaußenseite (sh. Fig.1), vorzugsweise über die Schalterblende (B) des Gerätes oder aber hinter der Gerätetür (2) im Gerätegehäuse (9) bedienbar angeordnet werden, wie z. B. die Fig. 2 zeigt.In the upper area of the device, a manually operated switch (trigger switch 13) or the like which is operatively connected to the control device (11) or the like is provided for the door movement control. The trigger switch (13) can be arranged on the outside of the device (see Fig. 1), preferably via the switch panel (B) of the device or behind the device door (2) in the device housing (9), such as. B. Fig. 2 shows.
Mit einem von außen zugänglichen Auslöseschalter (13) gemäß Fig. 1 ist sowohl ein elektromotorisches vollständiges Öffnen (vollautomatischer Betrieb) als auch das vollständige oder nur teilweise (halbautomatische) elektromotorische Schließen der Gerätetür (2) einsteuerbar. Bei verdeckt hinter der Tür angeordnetem Auslöseschalter (13) muß die Gerätetür (2) zuerst zumindest teilweise manuell (halbautomatisches Türöffnen) geöffnet werden, um danach den Auslöseschalter (13) für ein weiteres elektromotorisches Türöffnen betätigen zu können. Die bevorzugte Türöffnungsstellung ist auch hier die in Fig. 2 gezeigte Türstellung. Die Gerätetür (2) kann bei dieser Schalteranordnung aber auch vollständig manuell geöffnet werden. Bei einer ausbalancierten Gerätetür (2) durch eine aus Türfeder (15), Seilzug (14) und/oder Türgestänge bestehenden und am Türscharnier (16) angreifenden einstellbaren Türbremse zum Gewichtsausgleich (Fig. 1 bis 3) fällt die Tür bei leichtem manuellen Druck auf die Türoberkante selbsttätig und sanft aus der bevorzugten Türstellung in ihre unterste Lage (Fig. 3). Ein manuelles Führen der Gerätetür (2) bis in ihre Endstellung durch die Bedienungsperson ist nicht notwendig. Die Geschirrkörbe (4, 5, 6) können anschließend zum Be- oder Entladen aus dem Spülraum (3) herausgezogen werden. Die verdeckte Schalteranordnung stellt auch vorteilhaft eine einfache Sicherheitsmaßnahme gegen versehentliches Öffnen der Gerätetür (2) insbesondere durch Kinder dar.With an externally accessible trigger switch (13) according to FIG. 1, both an electromotive full opening (fully automatic operation) and the complete or only partial (semi-automatic) electromotive closing of the appliance door (2) can be controlled. If the trigger switch (13) is concealed behind the door, the appliance door (2) must first be opened at least partially manually (semi-automatic door opening) in order to then be able to actuate the trigger switch (13) for a further electromotive door opening. The preferred door opening position is also the door position shown in FIG. 2. With this switch arrangement, the appliance door (2) can also be opened completely manually. In the case of a balanced appliance door (2) by means of a door spring (15), cable pull (14) and / or door linkage and on the door hinge (16) attacking adjustable door brake for weight compensation (Fig. 1 to 3), the door falls automatically and gently from the preferred door position to its lowest position with light manual pressure on the top edge of the door (Fig. 3). Manual operation of the appliance door (2) into its end position by the operator is not necessary. The crockery baskets (4, 5, 6) can then be pulled out of the wash cabinet (3) for loading or unloading. The concealed switch arrangement also advantageously represents a simple safety measure against accidental opening of the appliance door (2), in particular by children.
Die Steuereinrichtung (11) für den elektromotorischen Antrieb kann Bestandteil der nicht näher gezeigten Geräteprogrammsteuerung sein und gibt in Abhängigkeit von der Geschirrkorbstellung im Spülraum (3), oder bei einem Herd durch die Gargutträgerstellung im Backraum, eine Türschließbewegung frei oder verhindert diese. Dies ist nachstehend ausführlich beschrieben.The control device (11) for the electromotive drive can be part of the appliance program control (not shown in more detail) and, depending on the position of the crockery basket in the wash cabinet (3), or in the case of a stove due to the position of the food support in the baking chamber, releases or prevents a door closing movement. This is described in detail below.
Bei geöffneter Geratetür (2) besteht die Gefahr, daß ein zum Beladen oder Entladen aus dem Spülraum (3) herausgezogener Geschirrkorb und/oder Besteckkorb (4, 5, 6) beim versehentlichen oder gewollten Betätigen des Auslöseschalters (13) durch die sich anschließende motorisch gesteuerte Bewegung der Gerätetür (2) in Schließstellung mit Wucht in den Spülraum (3) eingeschoben wird, und daß dabei Geschirrteile, Gläser oder dergl. zerbrechen können. Um dies zu verhindern ist die Türsteuerung von der jeweiligen Stellung der Geschirrkörbe (4, 5 ,6) im Spülraum (3) abhängig gemacht. Dafür ist an mindestens einem Geschirrkorb (4, 5, 6), oder bei einem Herd am Gargutträger, ein impulsauslösendes Schaltelement (17) und in der Wegstrecke (W) des aus dem Spül- oder Backraum (3) herausziehbaren Geschirrkorbes (4, 5, 6) oder des Gargutträgers ein impulsgebendes Schaltelement (18) vorzugsweise als Bestandteil der Steuereinrichtung (11) angeordnet. Das impulsgebende Schaltelement (18) gibt einerseits Meldung an die Steuereinrichtung (11), wenn ein Korb oder dergl. nicht vollständig in den Spülraum (3) eingeschoben ist und signalisiert andererseits aber auch eine ordnungsgemäße Geschirrkorbstellung. Bei herausgezogenem Korb oder Träger wird eine elektromotorische Schließbewegung der Gerätetür (2) verhindert und im anderen Fall freigegeben.When the appliance door (2) is open, there is a risk that a crockery basket and / or cutlery basket (4, 5, 6) pulled out for loading or unloading from the wash cabinet (3) if the trigger switch (13) is accidentally or intentionally actuated by the subsequent motor Controlled movement of the appliance door (2) in the closed position with force is inserted into the wash cabinet (3), and that dishes, glasses or the like can break. To prevent this, the door control is made dependent on the respective position of the crockery baskets (4, 5, 6) in the wash cabinet (3). For this, there is an impulse-triggering switching element (17) on at least one crockery basket (4, 5, 6), or in the case of a stove on the food support and in the path (W) of the crockery basket (4, 5 that can be pulled out of the washing or baking chamber (3) , 6) or the food support, a pulse-generating switching element (18) is preferably arranged as part of the control device (11). The pulse-generating switching element (18) notifies the control device (11) when a basket or the like is not fully inserted into the wash cabinet (3) and also signals that the basket is in the correct position. If the basket or carrier is pulled out, an electromotive closing movement of the appliance door (2) is prevented and released in the other case.
Das impulsgebende Schaltelement (18) ist zweckmäßig in Korbhöhe des zugeordneten Geschirrkorbes (4, 5, 6) im Bereich einer Spülraumwand (3) bzw. im Türwandbereich vorzugsweise außenseitig an der entsprechenden Wand (19) vorgesehen, wie in Fig. 3 gezeigt ist. Als impulsauslösende und impulsgebende Schaltelemente (17, 18) sind vorzugsweise elektrische bzw. elektronische Bauelemente, wie Dauermagnete, Reedkontakte, Hallgeneratoren, Schwingkreise oder dergl. berührungslos arbeitende Schaltmittel verwendet.

Aus der unteren Türstellung heraus erfolgt das elektromotorische Schließen der Gerätetür (2) vorzugsweise nur bis zu einer in Handgriffhöhe (H) des Gerätebedieners liegenden Türoffenstellung. Diese Vorzugstürstellung ist in Fig. 2 gezeigt. Die Türstellung genügt zum anfangs beschriebenen Befüllen der Dosiervorrichtungen (8) bzw. zum Teilbeladen des mittleren Geschirrkorbes (5) sowie zum vollständigen Beladen oder Entladen der Besteckschublade (6).From the lower door position, the electromotive closing of the appliance door (2) is preferably only carried out up to a door open position at handle height (H) of the appliance operator. This preferred door position is shown in Fig. 2. The door position is sufficient for filling the dosing devices (8) described initially or for partially loading the middle crockery basket (5) as well as for completely loading or unloading the cutlery drawer (6).
Bei einer teilweise nur bis in Handgriffhöhe (H) des Gerätebedieners elektromotorisch bewegten Gerätetür (2) genügt es, wenn auch nur die direkt in dem entsprechenden Türschließweg liegenden Geschirrkörbe (unterer und/oder mittlerer Geschirrkorb (4, 5)) bzw. Gargutträger mit den impulsauslösenden Schaltelementen (17) versehen werden.If the appliance door (2) is only moved electromotively up to the handle height (H) of the appliance operator, it is sufficient if only the crockery baskets (lower and / or middle crockery basket (4, 5)) or food carriers with the pulse-triggering switching elements (17) are provided.
Der erfindungsgemäße Türantrieb ist vorteilhaft bei einem Haushaltgerät, insbesondere bei einer Geschirrspülmaschine (1) oder einem Herd mit einer aus Türfeder (15), Seilzug (14) und/oder Türgestänge bestehenden und am Türscharnier (16) angreifenden Türbremse zum Gewichtsausgleich der Gerätetür (2) zu realisieren, wobei das Verstellgetriebe (12) die Gerätetür (2) mittelbar über den Seilzug (14) oder das Türgestänge bewegt. Dafür ist das Verstellgetriebe (12) an den Seilzug (14) oder an das Türgestänge an- und abkuppelbar ausgebildet.The door drive according to the invention is advantageous in a household appliance, in particular in a dishwasher (1) or a stove with a door brake consisting of a door spring (15), cable pull (14) and / or door linkage and acting on the door hinge (16) for balancing the weight of the appliance door (2 ) to realize, the adjustment gear (12) moving the appliance door (2) indirectly via the cable (14) or the door linkage. For this purpose, the adjustment gear (12) is designed to be connected and disconnected to the cable pull (14) or to the door linkage.
Als elektromotorischer Antrieb (10) ist für diese bevorzugte Ausführungsvariante ein nur in einer Drehrichtung arbeitender Elektromotor vorgesehen. Das Verstellgetriebe (12) besitzt einen vom Motor bewegten Endlosriementrieb (20) in Form eines Zahnriementriebes mit einem umlaufenden sich selbsttätig in den Seilzug (14) der Gerätetür (2) ein- und ausklinkenden Mitnehmer (21), wobei an einem starren Seilzugabschnitt (22) des am Türscharnier (16) angelenkten Seilzuges (14) ein entsprechender Gegenmitnehmer (23) festgesetzt ist. Der starr ausgebildete Seilzugabschnitt (22) ist in einem Lagerbock (24) gerade geführt. Die als Kupplungselemente wirkenden Mitnehmer (21, 23) des Verstellgetriebes (12) sowie die Federspannung der Türbremse sind vorzugsweise nachjustierbar ausgebildet.For this preferred embodiment, an electric motor that operates only in one direction of rotation is provided as the electric motor drive (10). The adjustment gear (12) has an endless belt drive (20) moved by the motor in the form of a toothed belt drive with a rotating driver (21) that automatically clicks in and out of the cable pull (14) of the appliance door (2), with a rigid cable pull section (22 ) of the cable hinge (16) articulated on the door hinge (16), a corresponding counter-driver (23) is fixed. The rigid cable section (22) is straight in a bearing block (24). The drivers (21, 23) of the adjustment gear (12) acting as coupling elements and the spring tension of the door brake are preferably designed to be readjustable.
Der Endlosriementrieb (20) sowie der Seilzug (14) verlaufen ohne seitliche Auslenkung über eine vorbestimmte Wegstrecke (W) zum Ein- und Ausklinken der Mitnehmer (21) mit Abstand parallel zueinander. Dabei ist dem Mitnehmer (21) am Endlosriementrieb (20) dem Trum gegenüberliegend ein Gegenhalter (25) zugeordnet, der den elastischen Zahnriemen des Endlosriementriebes (20) daran hindert, nach hinten auszuweichen. Durch diese Maßnahme wird ein versehentliches Abkuppeln des Antriebes verhindert. Die Wegstrecke (W) ist so bemessen, daß entweder ein vollständiges oder zumindest ein teilweises Schließen und/oder Öffnen der Gerätetür (2) möglich ist. Das gewählte Ausführungsbeispiel erlaubt ein elektromotorisches Teilschließen der Gerätetür (2) bis zur Öffnungsstellung gemäß Fig. 2.The endless belt drive (20) and the cable pull (14) run parallel to one another at a distance without lateral deflection over a predetermined distance (W) for engaging and disengaging the drivers (21). The driver (21) on the endless belt drive (20) opposite the run is assigned a counter-holder (25) which prevents the elastic toothed belt of the endless belt drive (20) from evading to the rear. This measure prevents accidental disconnection of the drive. The distance (W) is such that either a complete or at least a partial closing and / or opening of the appliance door (2) is possible. The selected exemplary embodiment permits partial electromotive closing of the appliance door (2) up to the open position according to FIG. 2.
Ausgehend von Fig. 1 öffnet die Bedienungsperson die Gerätetür (2) zum Ein- oder Ausräumen der Geschirrkörbe (4, 5, 6) manuell bis zur bevorzugten Öffnungsstellung (Handgriffhöhe H des Gerätebedieners) gemäß Fig. 2. Ab dieser Stellung senkt sich die Tür durch leichten Druck auf die Türoberkante selbsttätig und sanft durch die Wirkung der Türbremse bis in die unterste Stellung gemäß Fig. 3. Dabei wandert der Gegenmitnehmer (23) des sich bewegenden Seilzuges (14) von seiner oberen weit außerhalb des Zahnriementriebes (20) befindlichen Lage bis zum oberen Ende des Kupplungsweges des Zahnriemens und bei zunehmender Federwirkung bzw. Federspannung der Türbremse weiter bis zum untersten Ende der Wegstrecke (W). Soll die Gerätetür (2) nach der Geschirrkorbbeladung geschlossen werden, so wird der Auslöseschalter (13) betätigt und die Gerätetür (2) bewegt sich gesteuert vom elektromotorischen Antrieb (10) und dem Verstellgetriebe (12) automatisch bis zur Handgriffhöhe (H) des Bedieners zurück. Ohne Mühe kann die Bedienungsperson in aufrechter Bedienhaltung den weiteren Schließvorgang dann manuell vornehmen. Dieser aus einer motorischen und einer manuellen Schließbewegung resultierende Schließvorgang wird als halbautomatischer Türschließvorgang bezeichnet.Starting from FIG. 1, the operator manually opens the appliance door (2) for clearing or clearing the crockery baskets (4, 5, 6) up to the preferred opening position (handle height H of the appliance operator) according to FIG. 2. From this position the door lowers automatically and gently through the action of the door brake to the lowest position according to FIG. 3 by light pressure on the upper edge of the door. The counter-driver (23) of the moving cable (14) moves from its upper position located far outside the toothed belt drive (20) up to the upper end of the coupling path of the toothed belt and with increasing spring action or spring tension of the door brake further up to the lowest end of the distance (W). If the appliance door (2) is to be closed after loading the crockery basket, the trigger switch (13) is actuated and the appliance door (2) moves automatically up to the handle height (H) of the operator, controlled by the electromotive drive (10) and the adjustment gear (12) back. The operator can then carry out the further closing process manually without any effort in an upright operating position. This closing process, which results from a motorized and a manual closing movement, is referred to as a semi-automatic door closing process.
Beim motorgesteuerten Türschließen greift der Mitnehmer (21) des Zahnriementriebes (20) hinter den Gegenmitnehmer (23) des Seilzuges (14) oder eines äquivalenten Türgestänges und zieht hierdurch den Seilzug (14) zurück. Die Kupplungsverbindung wird erst wieder gelöst wenn der Mitnehmer (21) seine Richtung am oberen Ende der Wegstrecke (W) ändert. Ein aus dem Spülraum (3) herausgezogener Korb (4, 5 und/oder 6) hingegen verhindert den motorischen Türschließvorgang.
Für einen voll- oder halbautomatischen Türöffnungsvorgang ist der Antrieb (10) in seiner Drehrichtung entsprechend umkehrbar auszubilden.When the door is closed by a motor, the driver (21) of the toothed belt drive (20) engages behind the counter driver (23) of the cable pull (14) or an equivalent door linkage and thereby pulls back the cable pull (14). The coupling connection is only released again when the driver (21) changes its direction at the upper end of the path (W). One pulled out of the wash cabinet (3) Basket (4, 5 and / or 6), on the other hand, prevents the motorized door closing process.
For a fully or semi-automatic door opening process, the drive (10) must be reversible in its direction of rotation.
Der elektromotorische Antrieb sowie das Verstellgetriebe (12) sind vorzugsweise auf einer gemeinsamen Trägerplatte (26) montiert, die zwischen der Geräteaußenwand und dem angrenzenden Spülraum (3) (oder Backraum) angeordnet und als separat prüf- und auswechselbare Baueinheit ausgebildet ist.The electromotive drive and the adjusting mechanism (12) are preferably mounted on a common support plate (26), which is arranged between the outer wall of the device and the adjacent washing area (3) (or baking area) and is designed as a separately testable and replaceable unit.
Abweichend von dem hier beschriebenen Ausführungsbeispiel kann auch ein Verstellgetriebe (12) vorgesehen werden, daß direkt an der Gerätetür (2) angreift und hierfür beispielsweise als ein vom elektromotorischen Antrieb (10) bewegter Zahnstangenantrieb in Art einer beispielsweise nur am Türscharnier (16) der Gerätetür (2) gelenkig befestigten Schwinge ausgebildet ist. Bei dieser nicht näher gezeigten Variante ist die Schwinge mit einer allseitig geschlossenen Ausnehmung versehen, innerhalb welcher eine Verzahnung auf einer gerade verlaufenden Strecke ausgebildet ist, Innerhalb der Ausnehmung kämmt mit der Stangenverzahnung ein Zahnritzel des Antriebsmotors. Der Antriebsmotor ist lösbar am Gerätegehäuse (9) vorzugsweise im Sockelbereich des Haushaltgerätes angeordnet und zum Antrieb der Schwinge als drehrichtungsumkehrbarer Elektromotor (z. B. Scheibenwischermotor) mit einem Wechselgetriebe ausgebildet.In a departure from the exemplary embodiment described here, an adjustment gear (12) can also be provided which acts directly on the appliance door (2) and for this purpose, for example, as a rack and pinion drive moved by the electromotive drive (10) in the manner of, for example, only on the door hinge (16) of the appliance door (2) articulated rocker is formed. In this variant, which is not shown in detail, the rocker arm is provided with a recess which is closed on all sides and within which a toothing is formed on a straight line. A toothed pinion of the drive motor meshes with the rod toothing within the recess. The drive motor is detachably arranged on the device housing (9), preferably in the base area of the household appliance, and is designed to drive the rocker arm as a reversible electric motor (e.g. windshield wiper motor) with a change gear.
Um Fingerquetschungen oder ein Blockieren der Gerätetür (2) beim der motorgesteuerten Türbewegung zu vermeiden, wird das elektromotorische Schließen und/oder Öffnen der Gerätetür (2) vorzugsweise von einer nicht näher gezeigten Sicherheitsvorrichtung überwacht, welche im Gefahrenfall die gesteuerte Türbewegung selbsttätig unterbricht. Als Sicherheitsvorrichtung ist in zweckmäßiger Weise eine zwischen dem elektromotorischen Antrieb (10) und dem Verstellgetriebe (12) angeordnete mechanisch oder elektrisch wirkende Kupplung eingesetzt. Als zusätzliche Sicherheitsmaßnahme sind die Türendstellungen vorzugsweise über Endschalter gesteuert.In order to avoid pinching fingers or blocking the appliance door (2) during the motor-controlled door movement, the electromotive closing and / or opening of the appliance door (2) is preferably monitored by a safety device (not shown in more detail) which automatically interrupts the controlled door movement in the event of danger. A mechanically or electrically acting coupling arranged between the electromotive drive (10) and the adjustment gear (12) is expediently used as the safety device. As an additional safety measure, the door end positions are preferably controlled via limit switches.
