Description
Die vorliegende Erfindung betrifft einen automatischen Eisspender für den Einbau in einem Kältegerät, insbesondere einem Haushaltskältegerät, und ein mit einem solchen Eisbereiter ausgestattetes Kältegerät. Herkömmlicherweise umfasst ein solcher Eisspender zwei Funktionsgruppen, nämlich den eigentlichen Eiserzeuger, der wenigstens eine gekühlte Hohlform und ggf. Mittel zum Eindosieren von Wasser in die Hohlform und zum Auswerfen der fertigen Eisstücke umfasst, und einen Eisvorratsbehälter, in dem die fertigen Eisstücke bis zum Gebrauch aufbewahrt werden, ggf. mit Mitteln zum Auswerfen der Eisstücke aus dem Behälter.The present invention relates to an automatic ice dispenser for installation in a refrigeration appliance, in particular a household refrigeration appliance, and a refrigerator equipped with such an ice maker. Conventionally, such an ice dispenser comprises two functional groups, namely the actual ice maker, which comprises at least one cooled mold and optionally means for metering water into the mold and ejecting the finished pieces of ice, and an ice storage container in which stores the finished pieces of ice until use be, if necessary, with means for ejecting the pieces of ice out of the container.
Diese beiden Funktionsgruppen werden jeweils für sich in einem Kältegerät montiert. Im Falle des Nichtgebrauchs sollten sie durch einen Benutzer leicht ausbaubar sein, und auch der Wiedereinbau sollte bequem und sicher möglich sein. Ein Problem hierbei ist, dass der Eiserzeuger im Allgemeinen deutlich kleinere Abmessungen als der Eisvorratsbehälter hat und nahe der Rückwand, an eher unzugänglicher Stelle, in einem Kältegerät montiert wird. Dies macht seinen Ein- und Ausbau beschwerlich. Für einen Benutzer, der in dem Kältegerät zeitweilig Platz benötigt, ist es am einfachsten, nur den Eisvorratsbehälter auszubauen und den Eiserzeuger an Ort und Stelle zu belassen. Das ist unbefriedigend, weil der Eiserzeuger nur Platz belegt, aber nicht genutzt werden kann. Um sicherzustellen, dass der Eiserzeuger kein Eis produziert, wenn der Eisvorratsbehälter nicht da ist, um es aufzunehmen, muss ein Sensor vorgesehen werden, der den Eiserzeuger bei Fehlen des Eisvorratsbehälters automatisch ausschaltet.These two functional groups are each mounted separately in a refrigeration unit. In case of disuse, they should be easily expandable by a user, and also the replacement should be comfortable and safe possible. A problem here is that the ice maker is generally much smaller in size than the ice bin and is mounted near the back wall, in a rather inaccessible place, in a refrigerator. This makes its installation and removal cumbersome. For a user who temporarily requires space in the refrigerator, it is easiest to remove only the ice bin and leave the icemaker in place. This is unsatisfactory because the ice maker occupies only space, but can not be used. To ensure that the icemaker does not produce ice when the icemaker is not there to pick it up, a sensor must be provided which automatically shuts off the icemaker in the absence of the icebox.

Aufgabe der vorliegenden Erfindung ist, einen Eisspender anzugeben, der einfacher ein- und auszubauen ist und bei dem keine Gefahr des Betriebs des Eiserzeugers bei Fehlen des Eisvorratsbehälters besteht.The object of the present invention is to provide an ice dispenser, which is easier to install and remove and in which there is no risk of the operation of the ice maker in the absence of the ice storage container.
Die Aufgabe wird zum einen gelöst, indem bei einem Eisspender mit einem Eisvorratsbehältergehäuse und einem Eiserzeuger, der wenigstens eine mit Wasser befüllbare Hohlform umfasst, das Eisvorratsbehältergehäuse und der Eiserzeuger zu einer Baueinheit verbunden sind. So sind beide gemeinsam ein- und ausbaubar, und der mit dem Ein- und Ausbau des Eiserzeugers verbundene Aufwand entfällt. Da der Eiserzeuger immer zusammen mit dem Eisvorratsbehältergehäuse entnommen wird, besteht kein Bedarf nach Mitteln zum Unterbinden des Betriebs des Eiserzeugers bei Fehlen des Eisvorratsbehälters.The object is achieved on the one hand by the Eisvorratsbehältergehäuse and the ice maker are connected to form a structural unit in an ice dispenser with an ice storage container and an ice maker, which comprises at least one fillable with water mold. Thus, both can be installed and removed together, and the associated with the installation and removal of the ice maker expense is eliminated. Since the ice maker is always taken out together with the ice storage box, there is no need for means for inhibiting the operation of the ice maker in the absence of the ice storage bin.
Um einen korrekten Zusammenbau von Eisvorratsbehältergehäuse und Eiserzeuger zu gewährleisten, weisen beide ineinandergreifende Konturen auf, die den Zusammenbau nur in einer einzigen Konfiguration erlauben.To ensure proper assembly of ice bin casings and ice makers, both have interlocking contours that allow assembly in only a single configuration.
Zum Kühlen der Hohlform kann ein Kaltluftkanal am Eiserzeuger vorgesehen sein. Vorzugsweise hat dieser eine in das Eisvorratsbehältergehäuse mündende Auslassöffnung, so dass die durch den Kanal geführte Luft nach der Hohlform auch noch den Eisvorrat kühlen kann.For cooling the mold, a cold air duct may be provided on the ice maker. Preferably, this has an opening into the Eisvorratsbehältergehäuse outlet, so that the guided through the channel air after the mold can also cool the ice stock.
Die ineinandergreifenden Konturen können insbesondere dadurch gebildet sein, dass eine den Kaltluftkanal begrenzende Wand des Eiserzeugers in eine komplementäre Aussparung des Eisvorratsbehältergehäuses eingreift.The interlocking contours can be formed, in particular, in that a wall of the ice maker bounding the cold air duct engages in a complementary recess of the ice storage container housing.
Vorzugsweise verläuft der Kaltluftkanal unterhalb der Hohlform. So wird zum einen die Hohlform effizient gekühlt, zum anderen kann die Kaltluft nach Passieren der Hohlform ohne eine wesentliche Umlenkung in den Eisvorratsbehälter gelangen, der vorzugsweise etwas tiefer als die Hohlform angeordnet ist, damit Eis aus der Hohlform durch Schwerkraftwirkung in den Eisvorratsbehälter gelangen kann.Preferably, the cold air duct extends below the mold. Thus, on the one hand, the mold is cooled efficiently, on the other hand, the cold air can pass without passing through the mold without a significant deflection in the ice storage, which is preferably arranged slightly lower than the mold so that ice can get out of the mold by gravity into the ice storage.
Vorzugsweise sind das Eisvorratsbehältergehäuse und der Eiserzeuger an einem gemeinsamen Trägerteil befestigt. Das gemeinsame Trägerteil kann insbesondere eine Rückwand des Eisspenders bilden.Preferably, the Eisvorratsbehältergehäuse and the ice maker are attached to a common support member. The common carrier part can in particular form a rear wall of the ice dispenser.
Ein stromaufwärtiger Abschnitt des Kaltluftkanals, über den Kaltluft dem Eiserzeuger zugeführt werden kann, kann zweckmäßigerweise an dem Trägerteil gebildet sein.An upstream portion of the cold air duct, via which cold air can be supplied to the ice maker, can be expediently formed on the carrier part.
Wenn das Trägerteil eine Rückwand des Eisspenders ist, dann bietet es sich als zweckmäßig an, wenn der stromaufwärtige Abschnitt einerseits von der Rückwand des Eisspenders und andererseits von einer Rückwand des Kältegerätegehäuses begrenzt ist.If the support part is a rear wall of the ice dispenser, then it is expedient if the upstream section is delimited on the one hand by the rear wall of the ice dispenser and on the other hand by a rear wall of the refrigeration device housing.
Zum Abdichten des stromaufwärtigen Abschnitts kann zweckmäßigerweise eine Wand des stromaufwärtigen Abschnitts durch zwei benachbarte Rippen und einen in einen Zwischenraum zwischen den Rippen eingefügten Dichtstreifen gebildet sein. Dieser Dichtstreifen kann an die Rückwand des Kältegeräts oder eine andere geeignete Wandoberfläche dicht anschließen.For sealing the upstream portion, a wall of the upstream portion may conveniently be formed by two adjacent ribs and a sealing strip inserted in a space between the ribs. This sealing strip can connect tightly to the rear wall of the refrigerator or another suitable wall surface.
Das Eisvorratsbehältergehäuse ist vorzugsweise gegliedert in einen ersten Hohlraum zum Aufnehmen des Eises und einen zweiten Hohlraum, in dem ein Antriebsmotor eines im ersten Hohlraum angebrachten, zum Auswerfen des Eises aus dem Vorratsbehälter dienenden Förderwerkzeugs angeordnet ist.The Eisvorratsbehältergehäuse is preferably arranged in a first cavity for receiving the ice and a second cavity in which a drive motor of a mounted in the first cavity, is arranged for ejecting the ice from the storage container conveying tool.
Dieser zweite Hohlraum kann durch das Trägerteil verschlossen sein, etwa um den Motor oder andere Einbauten des zweiten Hohlraums vor Feuchtigkeit zu schützen.This second cavity may be closed by the support member, such as to protect the motor or other internals of the second cavity from moisture.
Zum Auswerfen von Eis aus der Hohlform weist der Eiserzeuger vorzugsweise einen durch die Hohlform hindurch bewegbaren Schieber auf. Dadurch entfällt die Notwendigkeit, die Hohlform selbst zum Auswerfen des Eises zu bewegen, und Raum, der ansonsten für die Bewegung der Hohlform frei gehalten werden müsste, kann anderweitig genutzt werden.For ejecting ice from the mold, the ice maker preferably has a slide which can be moved through the mold. This eliminates the need to move the mold itself to eject the ice, and space that would otherwise need to be kept clear for the movement of the mold can be used elsewhere.
Zwischen zwei Hohlformen kann eine zum Eisvorratsbehälter abschüssige Schrägfläche vorgesehen, auf die durch den Schieber aus der Hohlform herausgeschobene Eisstücke fallen können, um von dort in den Eisvorratsbehälter abzugleiten.Between two hollow molds, a sloping to the ice storage tank inclined surface may be provided, may fall on the pushed out of the mold by the slide pieces of ice to slide off from there into the ice storage container.
Ein Füllstandsfühler kann eine Einlassöffnung des Eisvorratsbehälters kreuzend bewegbar vorgesehen sein. Wenn die Bewegung des Füllstandsfühlers durch Eis behindert ist, ist das Fassungsvermögen des Eisvorratsbehälters erschöpft. In diesem Fall ist der Eiserzeuger auszuschalten.A filling level sensor may be provided so as to be capable of crossing an inlet opening of the ice storage container. If the movement of the level sensor is obstructed by ice, the capacity of the ice storage container is exhausted. In this case, the ice maker should be switched off.
Gegenstand der Erfindung ist ferner ein Kältegerät mit einem Eisspender der oben beschriebenen Art, an dessen Gehäuse der Eiserzeuger mittelbar über das Eisvorratsbehältergehäuse oder ein mit dem Eisvorratsbehältergehäuse gemeinsames Trägerteil verbunden ist. Da der Eiserzeuger ohne das Eisvorratsbehältergehäuse nicht im Kältegerät montierbar ist, besteht keine Möglichkeit, dass er versehentlich betrieben wird, ohne dass das produzierte Eis vom Eisvorratsbehälter aufgenommen werden könnte.The invention further relates to a refrigerator with an ice dispenser of the type described above, to the housing of the ice maker is indirectly connected via the Eisvorratsbehältergehäuse or a common with the Eisvorratsbehältergehäuse support member. Since the ice maker without the Eisvorratsbehältergehäuse is not mounted in the refrigerator, there is no possibility that he operated accidentally without the ice produced being able to be absorbed by the ice bin.

Der Eisbereiter 3 umfasst im Wesentlichen zwei über eine gemeinsame Rückwand verbundene Baugruppen, einen Eiserzeuger 5, in dem Eisstücke produziert werden, und ein Eisvorratsbehältergehäuse 6, in dem sie bis zum Gebrauch gelagert werden.The ice maker 3 essentially comprises two assemblies connected via a common back wall, an ice maker 5 in which pieces of ice are produced, and an ice storage container housing 6 in which they are stored until use.
Zum Eiserzeuger 5 gehört ein Tablett 7, in dem eine Mehrzahl von Hohlformen mit kreissektorförmigem oder halbzylindrischem Querschnitt gebildet sind. Fertige Eisstücke, die von einem später noch genauer beschriebenen Antriebsmechanismus aus den Hohlformen ausgeworfen werden, fallen über eine vordere Kante des Tabletts 7 herab in eine Vorratskammer, die einen Großteil des Eisvorratsbehältergehäuses 6 ausfüllt. In einer zweiten Kammer des Eisvorratsbehältergehäuses 6 ist ein Motor 13 zum Antreiben einer sich durch die Vorratskammer erstreckenden Förderwendel 14 und eines ummittelbar über dem Durchgang 4 angeordneten Mahlwerks 15 untergebracht.The ice maker 5 includes a
Den hinteren Bereich des Eisvorratsbehältergehäuses 6 bildet eine nach hinten offene Kammer, von der in
An der Unterkante jeder Seitenwand des Eisvorratsbehältergehäuses 6 sind zwei Aussparungen 58, 59 gebildet, die vorgesehen sind, um von Seitenwänden des Kältegerätekorpus abstehende Rippen aufzunehmen und so das Gehäuse 6 in dem Korpus zu verankern.At the lower edge of each side wall of the Eisvorratsbehältergehäuses 6 two
In einem vertikalen Bereich der Rückwand 18 ist eine kreisrunde Öffnung gebildet, in der ein flach zylindrisches Kupplungsstück 19 drehbar gehalten ist. In das Kupplungsstück 19 greift vorderseitig die Förderwendel 14 drehfest ein. An einer in der
Durch Drehen der Wendel 14 werden die Eisstücke in der Schublade 10 zu einer in der Figur nicht sichtbaren Ausgabeöffnung am vorderen Ende der Schublade geschoben. In eingeschobener Stellung der Schublade (

An die obere Kante der vorderen Wand 29 schließt sich eine leicht nach vorn abschüssige, an ihrem hinteren Rand mit hier ingesamt acht Kerben 32 versehene Schrägfläche 31 an.At the upper edge of the
Die Schale 27 ist vorgesehen, um das bereits erwähnte Tablett 7 - unter Aufrechterhaltung eines Luftspalts zwischen der Unterseite des Tabletts 7 und dem Boden der Schale 27 - aufzunehmen. Das Tablett 7 umfasst acht Hohlformen 33, entsprechend der Zahl der Kerben 32, von im Wesentlichen halbzylindrischem Querschnitt. Entlang der gemeinsamen Querschnittsachse der Hohlformen 33 erstreckt sich eine Welle 34, an der acht Finger 35 (siehe
Eine Rückwand 37 des Eisspenders ist in
Von der Rückseite der Rückwand 37 abstehende Rippen 41 begrenzen einen Kaltluftkanal 44, der von einem nicht dargestellten, unter dem Eisspender 3 im Kältegerät angeordneten Verdampfer gespeist wird. Die Rippen 41 sind jeweils paarweise angeordnet und begrenzen eine Nut, in der ein flexibler Dichtstreifen 42 geklemmt ist. Der Dichtstreifen steht über die Rippen 41 in Richtung der Rückwand des Kältegerätekorpus über, um diese im eingebauten Zustand zu berühren und so den Kaltluftkanal 44abzudichten.From the back of the
Eine zwischen den Rippen 41 in der Rückwand 37 gebildete Öffnung 43 mündet in die Vertiefung 28 der Schale. Durch die Öffnung 43 hindurch ist in
Ein Großteil der eingeblasenen Luft verlässt den Zwischenraum über die Schlitze 30 in der vorderen Wand 29 der Schale 27. Da die Schlitze 30 unter dem Niveau der Decke des Eisvorratsbehältergehäuses 6 liegen, wird die hindurch tretende Luft zum größten Teil in die Schublade 10 hinein gelenkt und hält die darin gelagerten Eisstücke gefroren.Much of the injected air leaves the gap via the
Vor der vorderen Wand 29 der Schale 27 ist ein Drahtbügel 47 zu sehen, der einerseits in dem Motor- und Schaltungsgehäuse 36 und andererseits in einer Gestellplatte 48 aufgehängt ist, die ihrerseits an einer von dem Gehäuse 36 abgewandten Schmalseite der Schale 7 angeschraubt ist. Der Drahtbügel 47 ist im Gehäuse 36 mit einem Motor und mit einem Schalter verbunden. Die Steuerschaltung ist eingerichtet, jeweils vor dem Auswerfen von Eis aus der Schale den Drahtbügel 47 mit Hilfe des Motors anzuheben und nach dem Auswerfen wieder absinken zu lassen. Wenn mit Hilfe des Schalters erfasst wird, dass der Drahtbügel 47 die in
Die Gestellplatte 48 bildet ferner ein Lager 49 für die Welle 34 und trägt einen federbelasteten Stift 50, der in ein kleines Loch an einer Seitenwange der Schale 27 eingreift. Wenn der Stift 50 gegen die Kraft der Feder in die Gestellplatte 48 hinein gedrückt wird, kann die Schale 27 nach vorn von einer sie an ihrem hinteren Rand unterstützenden, in der Fig. verdeckten Rippe der Rückwand 37 herunter gezogen und abgenommen werden.The
Eiserzeuger 5 und Vorratsbehältergehäuse 6 sind über die Rückwand 37 mechanisch zu einer Einheit verbunden, die nur als Ganzes in dem Kältegerät eingesetzt oder wieder entnommen werden kann. Infolge der gemeinsamen elektrischen Versorgung des Motors 13 und der Komponenten im Gehäuse 36 über den Steckverbinder 57 können auch die elektrischen Verbindungen für beide Funktionsgruppen mit einem Handgriff hergestellt und wieder gelöst werden.Ice maker 5 and reservoir housing 6 are mechanically connected via the
