Description

HAUSHALTSGERÄT MIT EINER EINE BREMSVORRICHTUNG AUFWEISENDEN TÜR HOUSEHOLD UNIT WITH A DOOR HAVING A BRAKING DEVICE
Die vorliegende Erfindung betrifft ein Haushaltsgerät, insbesondere ein Kältegerät wie einen Kühlschrank, mit einer Tür, die um eine Schwenkachse verschwenkbar ist, sowie mit einer Bremsvorrichtung zum Dämpfen der Schwenkbewegung der Tür.The present invention relates to a household appliance, in particular a refrigerator such as a refrigerator, with a door which is pivotable about a pivot axis, and with a braking device for damping the pivotal movement of the door.
Bei Haushaltsgeräten wie insbesondere Kältegeräten wird zur Verbesserung der Energieeffizienz zunehmend gewünscht, sogenannte Door-in-door-Lösungen vorzusehen, bei denen eine zusätzliche Tür in der eigentlichen Tür des Kältegeräts wie beispielsweise eines Kühlschranks vorgesehen ist, um einen vom Öffnen der "Haupttüre" unabhängigen Zugang zu einem Getränkefach oder zu einem an der Innenseite der Haupttüre angebrachten Absteller für Getränke zu ermöglichen. Da bei solchen Lösungen nicht mehr die Haupttüre geöffnet zu werden braucht und dadurch nicht mehr viel warme Luft in den Kühlschrank strömen kann, wird insgesamt weniger Kälteleistung und damit weniger Energie benötigt.In household appliances such as refrigeration appliances in particular, in order to improve energy efficiency, it is increasingly desired to provide so-called door-in-door solutions in which an additional door is provided in the actual door of the refrigeration appliance, such as a refrigerator, in order to obtain an independent opening of the "main door" To provide access to a drink compartment or to a stand for drinks on the inside of the main door. Since no longer the main door needs to be opened in such solutions and thus not much warm air can flow into the refrigerator, a total of less cooling capacity and thus less energy is needed.
Um die Ästhetik bei solchen Door-in-door-Lösungen nicht durch einen weiteren Griff zu stören, ist die in der Haupttüre angebrachte kleinere Tür im Regelfall mit einem sogenannten Push-push-Mechanismus versehen, bei dem sowohl das Öffnen der Tür als auch deren Schließung durch einfaches Andrücken durch beispielsweise die Hand eines Benutzers im Randbereich der Tür erfolgt. Für das Funktionieren des Push-push- Mechanismus ist im Regelfall eine Feder erforderlich, welche die selbsttätige Öffnung der Tür aus der Schließstellung heraus - entgegen der Richtung des Drückens durch die Hand - bewirkt oder zumindest unterstützt. Dies kann jedoch zu Problemen führen, dass dann die Tür, da sie nicht von einem Benutzer an einem Griff festgehalten wird, eine unkontrollierte und zu schnelle Bewegung ausführt. Dieses Problem tritt insbesondere dann auf, wenn die Schwenkachse der Tür horizontal angeordnet ist und sich die Bewegung der Tür bei deren Öffnung aufgrund der Schwerkraft verstärkt. Um eine derartige zu schnelle Bewegung zu vermeiden, ist in der US 7,059,693 B2 vorgeschlagen worden, an der Tür eine Dämpfungseinheit anzubringen, bei der ein Drehelement in einem ölgefüllten Behälter für die Dämpfung der Bewegung der Tür sorgt. In der Praxis erweist es sich jedoch als schwierig, angesichts der beengten Platzverhältnisse eine solche an der Tür angreifende Dämpfungseinheit anzubringen. Der vorliegenden Erfindung liegt die Aufgabe zugrunde, die vorgenannten Probleme des Stands der Technik zu vermeiden und ein Haushaltsgerät wie insbesondere ein Kältegerät zu schaffen, bei dem eine Dämpfungseinheit bzw. Bremsvorrichtung zum Dämpfen der Schwenkbewegung der Tür vorgesehen ist, die nicht nur zuverlässig arbeitet, sondern auch trotz der beengten Platzverhältnisse gut einbaubar ist.In order not to disturb the aesthetics with such door-in-door solutions by another handle, the attached in the main door smaller door is usually provided with a so-called push-push mechanism, in which both the opening of the door and their Closure is done by simply pressing through, for example, the hand of a user in the edge region of the door. For the functioning of the push-push mechanism is usually required a spring, which causes the automatic opening of the door from the closed position - contrary to the direction of pressing by hand - or at least supported. However, this can lead to problems that then the door, as it is not held by a user on a handle, performs an uncontrolled and too fast movement. This problem occurs in particular when the pivot axis of the door is arranged horizontally and the movement of the door increases when it is opened due to gravity. In order to avoid such too rapid movement, it has been proposed in US Pat. No. 7,059,693 B2 to attach a damping unit to the door, in which a rotary element in an oil-filled container ensures the damping of the movement of the door. In practice, however, it proves to be difficult, given the limited space to install such an attacking on the door damping unit. The present invention has for its object to avoid the aforementioned problems of the prior art and to provide a household appliance such as in particular a refrigerator, in which a damping unit or braking device is provided for damping the pivoting movement of the door, which not only works reliably, but also in spite of the cramped space is well installable.
Diese Aufgabe wird mit einem Haushaltsgerät gemäß Anspruch 1 gelöst. Vorteilhafte Weiterbildungen der Erfindung sind Gegenstand der abhängigen Ansprüche.This object is achieved with a household appliance according to claim 1. Advantageous developments of the invention are the subject of the dependent claims.
Das erfindungsgemäße Haushaltsgerät umfasst eine um eine Schwenkachse verschwenkbare Tür und eine Bremsvorrichtung zum Dämpfen der Schwenkbewegung der Tür. Die Erfindung zeichnet sich dadurch aus, dass eine Übertragungseinheit zum Übertragen der Rotation der Schwenkachse während der Schwenkbewegung der Tür auf eine Bremsachse vorgesehen ist, die bezüglich der Schwenkachse versetzt ist, und dass die Bremsvorrichtung dabei in Wirkverbindung mit der Bremsachse steht. In anderen Worten greift die Bremsvorrichtung nicht direkt an der Tür an, sondern an derThe household appliance according to the invention comprises a pivotable about a pivot axis door and a braking device for damping the pivotal movement of the door. The invention is characterized in that a transmission unit for transmitting the rotation of the pivot axis during pivotal movement of the door is provided on a brake axle, which is offset with respect to the pivot axis, and in that the brake device is in operative connection with the brake axle. In other words, the brake device does not attack directly on the door, but on the
Übertragungseinheit. Dadurch kann die Bremsvorrichtung an einer Stelle eingebaut werden, die an die herrschenden Platzverhältnisse optimal angepasst ist, was insbesondere in der unmittelbaren Nähe der sich bewegenden Tür sonst schwierig realisierbar wäre. Es ist hierbei festzuhalten, dass die Begriffe "Schwenkachse" und "Bremsachse" nicht nur so zu verstehen sind, dass sie sich auf die tatsächliche körperliche Ausgestaltung einer derartigen Achse wie beispielsweise in Form einer Welle beziehen, sondern dass sie auch im abstrakten Sinne des Wortes "Achse" zu verstehen sind. Das heißt, jedwede Form der Gestaltung einer solchen Achse soll von diesen Begriffen umfasst sein, so dass die Drehbewegung der Tür von deren Schwenkachse auf eine als Bremsachse bezeichnete andere Achse übertragen wird und die Bremsvorrichtung an dieser Bremsachse angreift.Transmission unit. As a result, the braking device can be installed at a location that is optimally adapted to the prevailing space conditions, which would otherwise be difficult to achieve, especially in the immediate vicinity of the moving door. It should be noted here that the terms "pivot axis" and "brake axis" are not to be understood to refer to the actual physical design of such an axis such as in the form of a wave, but that they also in the abstract sense of the word "Axis" are to be understood. That is, any form of design of such an axle should be encompassed by these terms, so that the rotational movement of the door from its pivot axis is transmitted to a designated as brake axle other axis and the brake device acts on this brake axle.
Eine besonders einfache Ausführungsform der Erfindung ergibt sich dann, wenn die Schwenkachse einen Bolzen umfasst oder beispielsweise aus zwei Bolzen an den Enden der Tür gebildet ist, und die Übertragungseinheit aus mehreren Zahnrädern aufgebaut ist, deren erstes drehfest bzw. nicht verrutschbar mit einem der Bolzen verbunden ist und deren letztes drehfest mit der Bremsvorrichtung verbunden ist. Eine solche Ausgestaltung ist mechanisch leicht zu realisieren und kostengünstig herzustellen, da entsprechende Zahnräder marktgängig und somit kostengünstig sind.A particularly simple embodiment of the invention results when the pivot axis comprises a bolt or is formed for example of two bolts at the ends of the door, and the transmission unit is constructed of a plurality of gears, the first rotatably or not verrutschbar connected to one of the bolts is and whose last is rotatably connected to the brake device. Such a design is mechanically easy to implement and inexpensive to manufacture, since corresponding gears are marketable and therefore cost.
Die Bremswirkung kann besonders gut dosiert werden, wenn das letzte Zahnrad bezüglich dem ersten Zahnrad untersetzt ist; in anderen Worten weist das letzte Zahnrad einen größeren Teilkreis auf als das erste Zahnrad.The braking effect can be particularly well metered when the last gear is reduced in relation to the first gear; in other words, the last gear has a larger pitch than the first gear.
Eine alternative Realisierungsmöglichkeit der Übertragungseinheit stellt ein Kardangelenk dar, dessen eines Ende drehfest mit einem Bolzen als Teil der Schwenkachse verbunden ist und dessen anderes Ende drehfest mit der Bremsvorrichtung verbunden ist.An alternative realization possibility of the transmission unit is a universal joint, one end of which is rotatably connected to a bolt as part of the pivot axis and the other end is rotatably connected to the braking device.
Es ist auch möglich, die Übertragungseinheit als Riementrieb mit zwei Riemenscheiben und einem Riemen auszubilden, bei dem eine erste Riemenscheibe drehfest mit einem Bolzen als Teil der Schwenkachse verbunden ist und eine zweite Riemenscheibe drehfest mit der Bremsvorrichtung verbunden ist.It is also possible to form the transmission unit as a belt drive with two pulleys and a belt, in which a first pulley rotatably connected to a bolt as part of the pivot axis and a second pulley is rotatably connected to the braking device.
Es ist besonders bevorzugt, die Schwenkachse in Form mindestens eines mit der Tür drehfest verbundenen Bolzens auszubilden und die Tür dadurch schwenkbar an einem Rahmen des Haushaltsgeräts zu lagern. Die an dem bzw. den Bolzen angreifende Übertragungseinheit und die Bremsvorrichtung befinden sich dabei außerhalb der Tür.It is particularly preferred to form the pivot axis in the form of at least one pin rotatably connected to the door and thereby pivotally mount the door on a frame of the household appliance. The acting on the bolt or the transfer unit and the braking device are doing outside the door.
Alternativ ist es möglich, die Übertragungseinheit und die Bremsvorrichtung mit der Bremse innerhalb eines in der Tür befindlichen Hohlraums anzuordnen. Um die Tür dann an einem Rahmen schwenkbar lagern zu können, ist der mindestens eine die Schwenkachse bildende Bolzen bevorzugt drehfest mit dem Rahmen verbunden. Bei dieser Ausführungsform ist es somit möglich, den Platz innerhalb der Tür für die Unterbringung der Übertragungseinheit und der Bremsvorrichtung zu nutzen.Alternatively, it is possible to arrange the transfer unit and the brake device with the brake within a cavity located in the door. In order to store the door then pivotally on a frame, the at least one pivot axis forming bolt is preferably rotatably connected to the frame. In this embodiment, it is thus possible to use the space inside the door for accommodating the transfer unit and the brake device.
Eine besonders zweckmäßige Anwendung der Erfindung ergibt sich dann, wenn die Tür in eine noch größere Türe - auch Haupttüre genannt - des Haushaltsgeräts eingebaut ist, wobei die größere Türe bevorzugt um eine im Wesentlichen vertikal angeordnete Türschwenkachse verschwenkbar ist. Diese größere Türe ist beispielsweise eine "normale" Türe eines Gefrier- oder Kühlschranks, die seitlich angelenkt ist. Besonders vorteilhaft ist es dabei, wenn die Schwenkachse der kleinen Tür im Wesentlichen horizontal angeordnet ist und die Tür somit durch Herunterklappen geöffnet wird. Hierbei bedeuten "im Wesentlichen" vertikal bzw. horizontal lediglich, dass es nicht auf die exakte Ausrichtung in einer bestimmten Orientierung ankommt, sondern dass durchaus Toleranzen aufgrund der Fertigung oder einer nicht ganz ebenen Aufstellung der betreffenden Geräte vorhanden sein können, ohne dass dies die Funktionsfähigkeit der Erfindung beeinträchtigt.A particularly expedient application of the invention results when the door is installed in an even larger door - also called main door - of the household appliance, wherein the larger door is preferably pivotable about a substantially vertically arranged door pivot axis. This larger door is for example a "normal" door of a freezer or refrigerator, which is articulated laterally. It is particularly advantageous if the pivot axis of the small door substantially is arranged horizontally and thus the door is opened by folding down. Here, "substantially" vertically or horizontally merely means that it does not depend on the exact orientation in a particular orientation, but that quite tolerances due to the production or a not very level installation of the devices in question can be present, without affecting the functionality of the invention impaired.
Die vorliegende Erfindung lässt sich dann einfach realisieren, wenn die Übertragungseinheit an der Schwenkachse der Tür angreift, und nicht an einer Stelle, die gegenüber der Schwenkachse versetzt ist. Bei dieser Ausführungsform muss daher nur die Rotationsbewegung übertragen werden und nicht eine Translationskomponente mitübertragen oder kompensiert werden, wie es bei einem Angriff der Übertragungseinheit an einer Stelle außerhalb der Schwenkachse der Fall wäre.The present invention can then be easily realized when the transmission unit engages the pivot axis of the door, and not at a location which is offset from the pivot axis. In this embodiment, therefore, only the rotational movement must be transmitted and not a translational component mitübertragen or compensated, as would be the case in an attack of the transmission unit at a location outside the pivot axis.
Eine besonders einfache, zuverlässig arbeitende und kostengünstige Bremsvorrichtung ist dadurch gegeben, dass sie aus einem in einem Zylinder beweglichen, durch Reibung gebremsten Kolben gebildet ist. Derartige Bremsvorrichtungen sind als Massenware verfügbar und werden beispielsweise von ITW-Ateco GmbH hergestellt. Bei solchen Bremsvorrichtungen rotiert ein Kolben aus beispielsweise Minion® in einem beispielsweise aus Delrin® hergestellten Gehäuse, gedämpft durch die Viskosität einer dazwischen eingebrachten Flüssigkeit.A particularly simple, reliable and cost-effective braking device is given by the fact that it is formed from a movable in a cylinder, braked by friction piston. Such braking devices are available as mass-produced goods and are produced, for example, by ITW-Ateco GmbH. In such braking devices, a piston of, for example, Minion® rotates in a housing made, for example, of Delrin®, dampened by the viscosity of a liquid introduced therebetween.

Nachfolgend wird als Beispiel für die Erfindung ein Kühlschrank mit einer seitlich angeschlagenen Türe beschrieben, in die eine kleinere, zusätzliche Tür eingebaut ist, die um eine horizontal angeordnete Schwenkachse verschwenkbar bzw. auf- und zuklappbar ist.Below is described as an example of the invention, a refrigerator with a laterally hinged door, in which a smaller, additional door is installed, which is pivotable about a horizontally arranged pivot axis and open and closed.
In Fig. 1 und 2 ist eine (kleine) Tür 12 eines erfindungsgemäßen Haushaltsgeräts bzw. Kühlschranks gezeigt. In der Tür 12 ist ein Bolzen 15, der als Schwenkachse 14 dient, über eine Bolzenaufnahme 16 drehfest mit der Tür 12 verbunden. Der Bolzen 15 ist in einem Rahmen 40 in einer großen, seitlich angeschlagenen Tür 50 verschwenkbar gelagert. Durch einen nicht dargestellten Push-push-Mechanismus am oberen Ende der Tür 12 kann diese geöffnet werden. Durch eine Schenkelfeder 60 (vgl. Fig. 3 und 3b), welche die Tür 12 in eine Offenstellung beaufschlagt, wird die Öffnungsbewegung der Tür 12 unterstützt. Beim Öffnen der Tür 12 dreht sich der drehfest mit ihr verbundene Bolzen 15 sowie ein drehfest auf dem Bolzen aufgestecktes, erstes Zahnrad 34 (vgl. auch Fig. 2). Gemäß Darstellung in Fig. 2 umfasst das erste Zahnrad 34 nur einige Zähne 34a auf einer Seite des Umfangs. Selbstverständlich können auch mehrere Zähne in einem Bereich des Umfangs oder auch - bei entsprechenden Platzverhältnissen - Zähne um den ganzen Umfang herum vorhanden sein. Das erste Zahnrad 34 kämmt mit einem zweiten Zahnrad 35, welches mit einem dritten Zahnrad 36 kämmt, das wiederum mit einem vierten, letzten Zahnrad 37 kämmt. Die Zahnräder 34 - 37 bilden somit eine Übertragungseinheit 30 zum Übertragen einer Drehbewegung der Schwenkachse 14 der Tür 12 auf eine Bremsachse 22, die zugleich auch die Drehachse des letzten Zahnrads 37 und gegenüber der Schwenkachse 14 versetzt ist.In Fig. 1 and 2, a (small) door 12 of a household appliance or refrigerator according to the invention is shown. In the door 12, a bolt 15, which serves as a pivot axis 14, rotatably connected via a pin receptacle 16 with the door 12. The bolt 15 is pivotally mounted in a frame 40 in a large, laterally hinged door 50. By a push-push mechanism, not shown, at the upper end of the door 12, this can be opened. By a leg spring 60 (see Fig. 3 and 3b), which acts on the door 12 in an open position, the opening movement of the door 12 is supported. When the door 12 is opened, the bolt 15 rotatably connected thereto rotates, as well as a first gearwheel 34, which is attached non-rotatably to the bolt (see also FIG. As shown in FIG. 2, the first gear 34 includes only a few teeth 34a on one side of the circumference. Of course, several teeth in a region of the circumference or - with appropriate space - teeth around the entire circumference around be present. The first gear 34 meshes with a second gear 35, which meshes with a third gear 36, which in turn meshes with a fourth, last gear 37. The gears 34 - 37 thus form a transmission unit 30 for transmitting a rotational movement of the pivot axis 14 of the door 12 on a brake axle 22, which is also the axis of rotation of the last gear 37 and offset from the pivot axis 14.
Aus Fig. 1 und. 2 ist ersichtlich, dass das Zahnrad 37 mehr Zähne 37a aufweist, als das erste Zahnrad 34 (bezogen auf deren jeweiligen Umfang); in anderen Worten weist das vierte Zahnrad 37 einen größeren Teilkreisdurchmesser auf als das erste Zahnrad 34. Dadurch ergibt sich eine Untersetzung der Drehbewegung des ersten Zahnrads 34. Hierdurch kann die Wirkung der an dem letzten Zahnrad 37 bzw. an dessen Achse 22 angreifenden Bremsvorrichtung 20 feiner dosiert werden, als dies beispielsweise bei einer Übersetzung der Rotationsbewegung des ersten Zahnrads 34 der Fall wäre. Die Bremsvorrichtung 20 besteht bei dieser Ausführungsform aus einem Kolben 28, der sich in einem Zylinder 27 bewegen kann und durch Reibung abgebremst ist. Der Kolben 28 weist dabei Eingriffsvorsprünge 26 auf, die in Ausnehmungen 37b des letzten Zahnrads 37 (vgl. Fig. 3h) eingreifen und somit bei Drehung des vierten Zahnrads 37 mitgedreht werden. Der Zylinder 27 dagegen wird durch eine Bremshalterung 24 ortsfest und drehfest gehaltert. In Fig. 3 sowie den Figuren 3a - 3k sind einzelne Komponenten des erfindungsgemäßen Kühlschranks zusammengebaut bzw. in Einzeldarstellungen abgebildet. Der Bolzen 15 der Tür 12 ist in einer Bolzenaufnahme 16, die Bestandteil der Tür ist, drehfest befestigt. Die Zahnräder 34 - 37 sind über einen Lagerflansch 38 und eine Zahnradfixierung 39 jeweils drehbar gehaltert. Die Schenkelfeder 60 (vgl. Fig. 3b) stützt sich mit einem ersten Schenkel 61 an dem Rahmen 40 der Türe 50 ab und greift mit einem zweiten Schenkel 62 in eine entsprechende Ausnehmung 34b des ersten Zahnrads 34 ein.From Fig. 1 and. 2, it can be seen that the gear 37 has more teeth 37a than the first gear 34 (relative to their respective circumference); In other words, the fourth gear 37 has a larger pitch circle diameter than the first gear 34. This results in a reduction of the rotational movement of the first gear 34. As a result, the effect of acting on the last gear 37 and at its axis 22 braking device 20 finer be metered, as this would be the case, for example, in a translation of the rotational movement of the first gear 34. The braking device 20 in this embodiment consists of a piston 28 which can move in a cylinder 27 and is braked by friction. In this case, the piston 28 has engagement projections 26 which engage in recesses 37b of the last gearwheel 37 (cf., FIG. 3h) and thus are rotated when the fourth gearwheel 37 is rotated. The cylinder 27, however, is held by a brake holder 24 stationary and rotationally fixed. In Fig. 3 and the figures 3a - 3k individual components of the refrigerator according to the invention are assembled or shown in individual representations. The bolt 15 of the door 12 is rotatably mounted in a bolt receptacle 16, which is part of the door. The gears 34-37 are each rotatably supported via a bearing flange 38 and a gear fixing 39. The leg spring 60 (see Fig. 3b) is supported with a first leg 61 on the frame 40 of the door 50 and engages with a second leg 62 in a corresponding recess 34b of the first gear 34 a.
Durch die vorstehend beschriebene Anordnung wird bei Drehung des mit der Tür 12 verbundenen Bolzens 15 diese Drehbewegung, die beim Öffnen der Tür 12 durch dieBy the arrangement described above, upon rotation of the bolt 12 connected to the door 15, this rotational movement, the 12 when opening the door through the
Schenkelfeder 60 forciert wird, durch die Zahnräder 34 - 37 von der durch den Bolzen 15 verlaufenden Schwenkachse 14 auf die unterhalb dieser Schwenkachse 14 verlaufende Bremsachse 22, die das letzte Zahnrad 37 mittig durchsetzt, übertragen. Die Bremsvorrichtung 20 mit dem in dem Zylinder 27 sich drehenden Kolben 28 liegt dabei genau auf der Bremsachse 22 und wirkt somit auf die Drehbewegung des viertenLeg spring 60 is forced, by the gears 34 - 37 of the extending through the bolt 15 pivot axis 14 on the below this pivot axis 14 extending brake axis 22, which passes through the last gear 37 centered. The brake device 20 with the piston 27 rotating in the cylinder 27 lies exactly on the brake axle 22 and thus acts on the rotational movement of the fourth
Zahnrads 37 bzw. die Bremsachse 22. Die Anordnung kann dabei durch entsprechende Wahl der Vorspannung der Schenkelfeder 60 und der Dämpfungseigenschaften der Bremsvorrichtung 20 so getroffen werden, dass - nachdem die Schenkelfeder 60 nach schon fortgeschrittener Öffnungsbewegung der Tür 12 nicht mehr wirkt und die Schwerkraft bei der sich immer weiter öffnenden Tür immer stärker angreift - ein unkontrolliertes, zu schnelles Herabbewegen der Tür 12 vermieden werden kann. Da die Bremsvorrichtung 20 nicht unmittelbar an der Schwenkachse 14 des Bolzens 15 bzw. der Tür 12 angreift bzw. angreifen muss, sondern ihre Funktion auch an einer gegenüber der Schwenkachse 14 versetzten Position entfalten kann, wo die Platzverhältnisse entsprechend besser gestaltet sind, kann der insgesamt zur Verfügung stehende Platz besser genutzt und die Anordnung optimiert werden. Eine typisches Beispiel des Zylinders 27 der Bremsvorrichtung 20 ist etwa 50 mm lang und weist einen Durchmesser von 20 mm auf. Wie insbesondere aus den Fig. 1 und 2 ersichtlich ist, sind bei der vorstehend beschriebenen Ausführungsform die Bremsvorrichtung 20, die Übertragungseinheit 30 in Form der Zahnräder 34 - 37 und die Schenkelfeder 60 sowie der Lagerflansch 38 und die Zahnradfixierung 39 außerhalb der Tür 12 angebracht. Es ist jedoch auch möglich, in der Tür einen mit gestrichelten Linien angedeuteten Hohlraum 19 vorzusehen und dieseThe arrangement can be made by appropriate selection of the bias of the leg spring 60 and the damping properties of the brake device 20 so that - after the leg spring 60 after already advanced opening movement of the door 12 no longer acts and gravity the ever-opening door attacks more and more - an uncontrolled, too fast down moving the door 12 can be avoided. Since the braking device 20 does not have to act or act directly on the pivot axis 14 of the bolt 15 or the door 12, but can also perform its function at a position offset from the pivot axis 14 where the space conditions are correspondingly better, the overall available space better used and the arrangement can be optimized. A typical example of the cylinder 27 of the brake device 20 is about 50 mm long and has a diameter of 20 mm. As can be seen in particular from FIGS. 1 and 2, in the embodiment described above, the brake device 20, the transmission unit 30 in the form of gears 34-37 and the leg spring 60 and the bearing flange 38 and the gear fixation 39 are mounted outside the door 12. However, it is also possible to provide in the door a direction indicated by dashed lines cavity 19 and this
Bauteile innerhalb des Hohlraums 19 anzuordnen. Das heißt, diese Bauelemente werden bei einer entsprechenden Bewegung mit der Tür mitbewegt bzw. verschwenkt. Dadurch kann der Platz innerhalb der Tür 12 genutzt werden, falls dies gewünscht wird. In diesem Fall muss dann allerdings der Bolzen 15 mit dem mit der großen Türe 50 fest verbundenen Rahmen 40 drehfest verbunden sein, so dass sich die Übertragungseinheit 30 relativ zu dem Bolzen 15 dreht. Die Funktionalität der über die Zahnräder 34 - 37 verbundenen Bremsvorrichtung 20 wird dadurch jedoch nicht beeinträchtigt.To arrange components within the cavity 19. That is, these components are moved with a corresponding movement with the door or pivoted. This allows the space within the door 12 to be used, if desired. In this case, however, then the bolt 15 must be rotatably connected to the frame 40 fixedly connected to the large door 50, so that the transmission unit 30 rotates relative to the bolt 15. However, the functionality of the connected via the gears 34-37 brake device 20 is not affected thereby.
Der Rahmen 40 kann so ausgestaltet werden, dass er ein Gehäuse 42 (vgl. Fig. 2) bildet, welches über einen nicht gezeigten Deckel verschlossen werden kann. Dieses Gehäuse 42 kann dann im Verlauf des Produktionsprozesses des Haushaltsgeräts mit Schaumstoff umgössen werden, um die Isolierwirkung der Türe 50, in der sich das Gehäuse 42 befindet, zu verbessern.The frame 40 may be configured to form a housing 42 (see Fig. 2) which may be closed by a lid, not shown. This housing 42 can then be encapsulated in the course of the production process of the household appliance with foam to improve the insulating effect of the door 50, in which the housing 42 is located.
Statt die vorstehend beschriebene Übertragungseinheit 30 in Form von Zahnrädern 34 - 37 auszubilden, kann auch ein Kardangelenk oder ein Riementrieb mit zwei oder mehr Riemenscheiben sowie entsprechenden Riemen vorgesehen werden, womit in entsprechender weise die Dreh- bzw. Schwenkbewegung der Tür 12 von deren Schwenkachse 14 auf eine hiervon beabstandete Bremsachse 22 übertragen werden kann.Instead of the above-described transmission unit 30 in the form of gears 34 - 37 form, a universal joint or a belt drive with two or more pulleys and corresponding belt can be provided, which in a corresponding manner, the rotational or pivotal movement of the door 12 of the pivot axis 14th can be transmitted to a brake axle 22 spaced therefrom.
Als für praktische Zwecke besonders geeignetes Material für das erste Zahnrad 34 ist Zinkdruckguss zu nennen, während die übrigen Zahnräder sowie auch die anderen Komponenten vorzugsweise aus POM (Polyoxymethylen) hergestellt sind. Selbstverständlich können diese Komponenten auch aus gefrästen Stahlteilen oder entsprechenden, gegebenenfalls durch Glasfasern verstärkten, Kunststoffen hergestellt sein. Vorstehend wurde ein Kühlschrank mit links angeschlagener großer Türe und unten angeschlagener kleiner Tür als Beispiel für ein Haushaltsgerät gemäß der Erfindung angegeben. Selbstverständlich ist die Erfindung auch bei anderen Arten von Haushaltsgeräten einsetzbar, bei denen eine solche oder ähnliche Door-in-door- Anordnung gewünscht ist.Zinc diecasting is to be mentioned as material which is particularly suitable for practical purposes for the first gearwheel 34, while the remaining gearwheels as well as the other components are preferably made of POM (polyoxymethylene). Of course, these components can also be made of milled steel parts or corresponding, possibly reinforced by glass fibers, plastics. In the above, a left-hinged large door refrigerator and a small-door down-hinged refrigerator have been exemplified as a household appliance according to the invention. Of course, the invention is also applicable to other types of household appliances, in which such or similar door-in-door arrangement is desired.
