Description

Kältegerät mit höhenverstellbarem Kühlgutträger Refrigerating appliance with height-adjustable refrigerated goods carrier
Die vorliegende Erfindung betrifft ein Kältegerät mit einem von einem wärmeisolierenden Gehäuse umschlossenen Innenraum und einem in dem Innenraum höhenverstellbaren Kühlgutträger. Ein solches Kältegerät, bei dem ein Kühlgutträger an einer an der Rückwand des Gehäuses angebrachten vertikalen Trägerschiene von Hand höhenverstellbar ist, ist z.B. aus DE 101 45 141 A1 bekannt.The present invention relates to a refrigerator with an enclosed by a heat-insulating housing interior and a height-adjustable in the interior refrigerated goods. Such a refrigerator, in which a refrigerated goods is manually adjustable in height at a mounted on the rear wall of the housing vertical support rail is, for example, known from DE 101 45 141 A1.
Ein Problem dieses bekannten Kältegerätes ist, dass es zum Höhenverstellen des Kühlgutträgers erforderlich ist, diesen leicht zu kippen, was die Gefahr mit sich bringt, dass auf dem Kühlgutträger abgestellte Gegenstände verrutschen können, und dass ein Benutzer, wenn er den Kühlgutträger von einer Raststufe lösen und an einer anderen aufhängen will, zwischenzeitlich das gesamte Gewicht des Kühlgutträgers und der evtl. darauf abgestellten Gegenstände tragen muss. Dadurch ist der Benutzer häufig gezwungen, vor dem Höhenverstellen den Kühlgutträger leer zu räumen, was insofern lästig ist, als das Bedürfnis, den Kühlgutträger in der Höhe zu verstellen, vor allem dann auftritt, wenn dieser beladen ist und der Benutzer feststellt, dass er zum Unterbringen von mehr Kühlgut, sei es auf dem Kühlgutträger oder darunter, diesen in einer anderen Höhe platzieren muss.A problem of this known refrigeration device is that it is necessary to adjust the height of the refrigerated goods, this easily tilt, which brings with it the danger that can be on the refrigerated goods parked items slip, and that a user when he solved the refrigerated goods from a stop and wants to hang on another, in the meantime, the entire weight of the refrigerated goods carrier and the possibly parked objects must wear. As a result, the user is often forced to clear the refrigerated goods before empty height adjustment, which is troublesome in the sense that the need to adjust the refrigerated goods in height, especially occurs when it is loaded and the user determines that he Store more refrigerated goods, whether on the refrigerated goods carrier or below, place it at a different height.
Aufgabe der Erfindung ist daher, ein Kältegerät zu schaffen, das eine Höhenverstellung eines Kühlgutträgers in horizontaler Stellung gestattet, ohne dass der Benutzer dabei das Gewicht des Kühlgutträgers und ggf. darauf abgestellter Gegenstände tragen muss.The object of the invention is therefore to provide a refrigeration device which allows a height adjustment of a refrigerated goods carrier in a horizontal position without the user having to carry the weight of the refrigerated goods carrier and possibly objects parked thereon.
Die Aufgabe wird dadurch gelöst, dass der Kühlgutträger mit wenigstens einer vertikalen, drehantreibbaren Gewindespindel im Gewindeeingriff ist. Durch Drehen der Gewindespindel gelingt eine parallele Höhenverstellung des Kühlgutträgers, während dessen Gewicht von der Gewindespindel bzw. deren Lagerung im Gehäuse des Kältegeräts aufgefangen wird.The object is achieved in that the refrigerated goods with at least one vertical, rotatably driven threaded spindle is in threaded engagement. By turning the threaded spindle manages a parallel height adjustment of the refrigerated goods, while the weight of the threaded spindle or its storage in the housing of the refrigerator is collected.
Die Gewindespindel kann manuell drehantreibbar sein, einer komfortableren Ausgestaltung zufolge ist sie durch einen Motor drehangetrieben. Um eine Höhenverstellung des Kühlgutträgers über einen vorgesehenen Höhen bereich hinaus zu verhindern, ist vorzugsweise an der Gewindespindel wenigstens ein durch den Kühlgutträger betätigter Endabschalter angeordnet, vorzugsweise zwei Endabschalter, die die Bewegungsfreiheit des Kühlgutträgers sowohl nach oben als auch nach unten begrenzen.The threaded spindle can be manually driven in rotation, according to a more comfortable embodiment, it is rotationally driven by a motor. In order to prevent a height adjustment of the refrigerated goods carrier area beyond an intended heights, preferably at the threaded spindle at least one operated by the Kühlgutträger Endabschalter arranged, preferably two Endabschalter that limit the freedom of movement of the refrigerated goods both upward and downward.
Zweckmäßigerweise ist die Gewindespindel über eine Schnecke an eine horizontale Abtriebswelle des Motors gekoppelt.Conveniently, the threaded spindle is coupled via a worm to a horizontal output shaft of the motor.
Der besseren Stabilität wegen ist der Kühlgutträger vorzugsweise auf zwei Gewindespindeln abgestützt, die drehgekoppelt sein sollten, um eine gleichmäßige Höhenverstellung des Kühlgutträgers an beiden Gewindespindeln zu gewährleisten.For better stability, the refrigerated goods carrier is preferably supported on two threaded spindles, which should be rotationally coupled in order to ensure a uniform height adjustment of the refrigerated goods carrier on both threaded spindles.
Die Drehkopplung kann dadurch hergestellt sein, dass jeder Spindel eine Schnecke zugeordnet ist und die zwei Schnecken drehfest an einer gemeinsamen Welle angebracht sind.The rotary coupling can be made by assigning a worm to each spindle and the two worms are non-rotatably mounted on a common shaft.
Diese gemeinsame Welle kann gleichzeitig die Abtriebswelle des Motors sein; vorzugsweise ist sie an die Abtriebswelle des Motors über einen Riementrieb, insbesondere über einen Zahnriemen, gekoppelt.This common shaft can simultaneously be the output shaft of the engine; Preferably, it is coupled to the output shaft of the engine via a belt drive, in particular via a toothed belt.
Die Gewindespindel ist vorzugsweise in einer an einer Wand des Gehäuses angebrachten vertikalen Führungsnut aufgenommen, und zwar vorzugsweise in einer Hinterschneidung der Führungsnut, so dass sie von außerhalb nicht sichtbar ist.The threaded spindle is preferably received in a mounted on a wall of the housing vertical guide groove, preferably in an undercut of the guide, so that it is not visible from outside.
Die Führungsnut ist vorzugsweise auf einem Teil ihrer Länge, der vorzugsweise nicht zum Verstellbereich des an der Gewindespindel angreifenden Kühlgutträgers gehört, mit Raststufen zum Verrasten eines weiteren Kühlgutträgers versehen.The guide groove is preferably provided on a part of its length, which preferably does not belong to the adjustment region of the chuck carrier acting on the threaded spindle, with latching steps for latching a further chilled goods carrier.

Fig. 1 zeigt in einer perspektivischen Ansicht einen Korpus 1 eines Kältegeräts gemäß der vorliegenden Erfindung. Eine an die offene Vorderseite des Korpus 1 angelenkte Tür ist in der Fig. weggelassen. Am rechten Rand der Rückwand 2 ist eine in die Rückwand 2 eingelassene vertikale Trägerschiene 3 zu erkennen, in deren zum Innenraum hin offenen Eingangsschlitz 4 mehrere Tragarme 5, 6 eingreifen. Eine entsprechende Trägerschiene 3 mit Tragarmen 5, 6 ist, in der Fig. von einer Seitenwand der Korpus 1 verdeckt, am linken Rand der Rückwand 2 eingelassen. Je ein Paar von gleich hohen Tragarmen 5, 6 trägt eine Fachbodenplatte 7, die in der Fig. durchsichtig dargestellt sind und als Scheiben aus einem Sicherheitsglas realisiert sein können. Die unteren Tragarme 6 ruhen jeweils auf Raststufen, die im Innern der Trägerschienen 3 verborgen sind.Fig. 1 shows a perspective view of a body 1 of a refrigerator according to the present invention. A hinged to the open front of the body 1 door is omitted in the figure. On the right edge of the rear wall 2 a recessed into the rear wall 2 vertical support rail 3 can be seen, in which the interior open towards the entrance slot 4 more support arms 5, 6 engage. A corresponding carrier rail 3 with support arms 5, 6 is, in the figure concealed by a side wall of the body 1, embedded on the left edge of the rear wall 2. Depending on a pair of equally high support arms 5, 6 carries a shelf plate 7, which are shown in the Fig. Transparent and can be realized as panes of a safety glass. The lower support arms 6 each rest on latching steps, which are hidden inside the support rails 3.
Fig. 2 zeigt einen Teilschnitt durch die Rückwand 2 des Korpus 1 und deren Umgebung in einer Ebene oberhalb der Tragarme 5. Wie in diesem Schnitt zu erkennen, haben dieFig. 2 shows a partial section through the rear wall 2 of the body 1 and its surroundings in a plane above the support arms 5. As can be seen in this section, the
Trägerschienen 3 jeweils eine hinterschnittene Führungsnut 9, wobei in derSupport rails 3 each have an undercut guide groove 9, wherein in the
Hinterschneidung 10 der Führungsnut 9 eine Gewindespindel 8 sich vertikal erstreckt und mit einem Innengewinde in Eingriff steht, das an einem in die Hinterschneidung 10 vorspringenden Bereich des Tragarms 5 gebildet ist. Die Gewindesteigung der Spindel 8 ist gering, so dass die Spindel nicht durch das auf ihr lastende Gewicht des Tragarms 5 und die von ihm getragene Last in Drehung versetzt wird. - A -Undercut 10 of the guide groove 9, a threaded spindle 8 extends vertically and is in engagement with an internal thread, which is formed on a projecting into the undercut 10 portion of the support arm 5. The thread pitch of the spindle 8 is small, so that the spindle is not rotated by the load on her weight of the support arm 5 and the load carried by him in rotation. - A -
An einer Seitenwand der linken Trägerschiene 3 ist eine Öffnung gebildet, durch die eine Taste 11 eines außen an der Trägerschiene 3 angebrachten Begrenzungsschalters 12 in die Führungsnut 9 eingreift. Wenn der Tragarm 5 die Taste 11 erreicht, drückt er diese aus der Führungsnut 9 heraus und öffnet dadurch einen Kontakt des Begrenzungsschalters 12, auf dessen Funktion später noch eingegangen wird.On an end wall of the left-hand carrier rail 3, an opening is formed through which a key 11 of a limit switch 12 mounted externally on the carrier rail 3 engages in the guide groove 9. When the support arm 5 reaches the key 11, it pushes it out of the guide groove 9 and thereby opens a contact of the limit switch 12, whose function will be discussed later.
Fig. 3 zeigt einen zu Fig. 2 analogen Teilschnitt in einer höheren Ebene, benachbart zur Decke des Korpus 1. Hier, am oberen Ende der Gewindespindeln 8, ist an diesen jeweils drehfest ein Schneckenrad 13 angeordnet, das mit einer Schnecke 14 kämmt und das Schneckengetriebe bildet. Die zwei Schnecken 14 sind von einer gemeinsamen Welle 15 getragen, die die Spindeln 8 aneinander drehkoppelt und dadurch gewährleistet, dass die zwei Tragarme 5 stets gleiche Höhenverschiebungen ausführen.Fig. 3 shows an analogous to Fig. 2 partial section in a higher plane, adjacent to the ceiling of the body 1. Here, at the upper end of the threaded spindles 8, a worm wheel 13 is rotatably connected to each of these, which meshes with a worm 14 and the Forms worm gear. The two screws 14 are supported by a common shaft 15 which rotatably couples the spindles 8 to each other and thereby ensures that the two support arms 5 always perform equal height displacements.
Die Welle 15 ist gemäß einer ersten Ausgestaltung und wie in Fig. 4 gezeigt, gleichzeitig Abtriebswelle eines Elektromotors 16. Um die Welle 15 platzsparend eng benachbart zur Rückwand 2 führen zu können, ist der Elektromotor 16 teilweise in einer Nische der Rückwand 2 aufgenommen. Motor 16 und Welle 15 sind durch eine Kunststoffschale 17 vom Innenraum des Kältegeräts getrennt.The shaft 15 is according to a first embodiment and as shown in Fig. 4, at the same time output shaft of an electric motor 16. To the shaft 15 space-saving close to the rear wall 2 to lead, the electric motor 16 is partially received in a niche of the rear wall 2. Motor 16 and shaft 15 are separated by a plastic shell 17 from the interior of the refrigerator.
Einer in Fig. 5 in einem zu Fig. 4 analogen Schnitt dargestellten zweiten Ausgestaltung zufolge ist die gemeinsame Welle 15 der Schnecken 14 an einen Elektromotor 16 über einen Zahnriementrieb 18 gekoppelt, der aus einem an der Welle 15 montierten Ritzel 19 und einem Ritzel 20 auf einer Abtriebswelle des Motors 16 gebildet ist und untersetzend ausgelegt ist. Diese Ausgestaltung erlaubt es, die Welle 15 eng benachbart zur RückwandA second embodiment shown in FIG. 5 in a section analogous to FIG. 4, the common shaft 15 of the screws 14 is coupled to an electric motor 16 via a toothed belt drive 18, which consists of a pinion 19 mounted on the shaft 15 and a pinion 20 an output shaft of the motor 16 is formed and is designed by reducing. This configuration allows the shaft 15 closely adjacent to the rear wall
2 des Korpus zu führen, ohne dass in dieser eine Nische für den Motor 16 vorgesehen werden muss.2 of the body, without that in this a niche for the engine 16 must be provided.
Bei den Ausgestaltungen der Fig. 4 und 5 ist der Elektromotor 16 jeweils zwischen den zwei Schnecken 14 an der Welle 15 angeordnet. Insbesondere im Falle des über den Zahnriemen 18 gekoppelten Motors ist es aber auch denkbar, das Ritzel 19 an einem über die Schnecken 14 hinaus zu einer benachbarten Seitenwand des Korpus 1 hin überstehenden Fortsatz 21 der Welle 15 (siehe Fig. 3) anzuordnen und den Motor 16 zusammen mit einer Schnecke 14 und dem von ihr angetriebenen Zahnrad 13 in einem gemeinsamen Gehäuse unterzubringen. Der Elektromotor 16 ist über einen nicht gezeigten Schalter ein- und ausschaltbar und in seiner Drehrichtung steuerbar. Mit diesem Schalter in Reihe ist der Begrenzungsschalter 12 angeordnet, um eine Verstellbewegung der Tragarme 5 abzubrechen, sobald diese eine durch den Begrenzungsschalter 12 markierte obere oder untere Grenze ihres zulässigen Verstellbereichs erreichen. In the embodiments of FIGS. 4 and 5, the electric motor 16 is arranged in each case between the two screws 14 on the shaft 15. In particular, in the case of the motor coupled via the toothed belt 18, it is also conceivable to arrange the pinion 19 on an extension 21 of the shaft 15 (see FIG. 3) projecting beyond the screws 14 to an adjacent side wall of the body 1 and the motor 16 to accommodate together with a screw 14 and driven by her gear 13 in a common housing.
