Description

Die vorliegende Erfindung betrifft eine Abstellplatte zur Anbringung im Innenraum eines Kältegerätes. Derartige Abstellplatten sind bei modernen Kältegeräten häufig in Form einer in einen Kunststoffrahmen gefässten Glasplatte realisiert. Der Kunststoffrahmen schützt die Ränder der Glasplatte vor Beschädigung und ist mit abstehenden Stegen, Zapfen oder dergleichen versehen, die zur Aufhängung der Abstellplatte an den Seitenwänden eines Kältegeräte-Innenbehälters dienen.The present invention relates to a storage tray for mounting in the interior of a refrigerator. Such storage shelves are often realized in modern refrigerators in the form of a geften in a plastic frame glass plate. The plastic frame protects the edges of the glass plate from damage and is provided with protruding ridges, pins or the like, which serve to suspend the storage tray on the side walls of a refrigeration device inner container.

Um eine effektive Platznutzung zu ermöglichen, sollte sich eine solche Abstellplatte über einen möglichst großen Teil der Bodenfläche des Innenbehälters erstrecken. Dabei tritt jedoch das Problem auf, dass bei Kältegeräten in Coldwall-Bauweise. Kühlgut, das auf einer solchen Abstellplatte in Kontakt mit der Verdampferwand abgestellt ist, dazu neigt, an der Wand festzufrieren, da diese im Betrieb, auch wenn die Solltemperatur im Inneren des Kältegerätes positiv ist, ohne weiteres Temperaturen unter 0°C erreichen kann. Um einen Kontakt zwischen Kühlgut und Verdampferwand zu verhindern, ist eine Abstellplatte für ein solches Gerät häufig in ihrem rückwärtigen Bereich mit einem aufrechten Anschlagsteg versehen, der eine zu enge Nachbarschaft von Kühlgut und Verdampferwand verhindert.In order to allow effective use of space, such a storage shelf should extend over as large a part of the bottom surface of the inner container. However, there is the problem that in refrigerators in Coldwall construction. Refrigerated goods, which are placed on such a storage tray in contact with the evaporator wall, tends to freeze on the wall, since these can easily reach temperatures below 0 ° C in operation, even if the target temperature inside the refrigerator is positive. In order to prevent contact between refrigerated goods and evaporator wall, a storage tray for such a device is often provided in its rear region with an upright stop web, which prevents too close a neighborhood of refrigerated goods and evaporator wall.

Bei No-Frost-Kühlgeräten gibt es normalerweise im Innenraum keine Oberflächen, die Temperaturen unter 0°C erreichen, so dass die Gefahr des Festfrierens an der Wand nicht besteht. Dennoch muss das Kühlgut von der Rückwand beabstandet gehalten werden, um einen Spalt zwischen der Rückwand und der rückwärtigen Kante der Abstellplatte freizuhalten, durch den Kaltluft zirkulieren kann, um so eine gleichmäßige Kühlung des Innenraumes auf seiner gesamten Höhe zu gewährleisten. Auch dies führt dazu, dass ein Teil der Tiefe des Innenraumes nicht gut nutzbar ist. Außerdem tritt das Problem auf, dass eine Luftströmung, die sich zwischen der Rückwand des Innenraumes und dieser Rückwand beabstandet gegenüberliegenden Kanten von Abstellplatten ausbildet, dazu neigt, geradlinig über die gesamte Höhe des Innenraumes zu fließen, so dass die Luftzirkulation in Fächern in mittlerer Höhe gering ist.In no-frost refrigerators, there are usually no surfaces in the interior that reach temperatures below 0 ° C, so there is no risk of freezing on the wall. Nevertheless, the refrigerated goods must be kept spaced from the rear wall to keep a gap between the rear wall and the rear edge of the storage tray, can circulate through the cold air, so as to ensure a uniform cooling of the interior space over its entire height. This also means that a part of the depth of the interior is not well usable. In addition, there is a problem that an airflow forming opposite edges of shelf boards spaced between the rear wall of the inner space and this rear wall tends to flow straight across the entire height of the inner space, so that the air circulation in mid-height shelves is low is.

Aus US 4,960,308 ist eine Abstellplatte für ein Kältegerät bekannt, deren Abstellfläche von einem Kunststoffrahmen eingefasst ist, der im Bereich der Rückwand und der Seitenwände des Kältegeräts Öffnungen für die Luftzirkulation aufweist.Out US 4,960,308 a storage plate for a refrigeration device is known, the storage space is bordered by a plastic frame having openings for air circulation in the region of the rear wall and the side walls of the refrigerator.

Aufgabe der vorliegenden Erfindung ist, eine Abstellplatte für ein Kältegerät zu schaffen, das eine effiziente Platzausnutzung ermöglicht.Object of the present invention is to provide a storage tray for a refrigerator, which allows efficient use of space.

Die Aufgabe wird durch die Merkmale gemäß Anspruch 1 gelöst. Bei einer Abstellplatte mit einem geschlossen ausgebildeten Hauptabschnitt ist ein Randabschnitt der Platte als Rost ausgeführt. Der Rost kann im Bedarfsfall dazu dienen, Kühlgut darauf abzustellen. Gleichzeitig ermöglichen diejenigen Teile des Rostes, die nicht mit Kühlgut bedenkt sind, einen Luftaustausch zwischen verschiedenen Seiten der Platte. Die Gefahr einer vollständigen Blockade des Rostes durch darauf stehendes Kühlgut ist in der Praxis vernachlässigbar, da die Benutzer in den seltensten Fällen eine Abstellplatte so dicht beladen, dass ihr Randabschnitt lückenlos überdeckt ist.The object is solved by the features of claim 1. In a storage tray with a closed main section, an edge portion of the plate is designed as a grate. If necessary, the grate can serve to deposit refrigerated goods. At the same time allow those parts of the grate, which are not considered with refrigerated goods, an exchange of air between different sides of the plate. The risk of a complete blockage of the grate by refrigerated goods standing thereon is negligible in practice, since the users rarely load a storage tray so densely that its edge portion is completely covered.

Außerdem kann eine für ein gewünschtes Maß an Luftaustausch ausreichende freie Querschnittsfläche des Rostes ohne weiteres dadurch bereitgestellt werden, dass dem Randabschnitt eine ausreichende Tiefe von insbesondere mehr als 3 cm gegeben wird.In addition, a free cross-sectional area of the grate sufficient for a desired degree of air exchange can be easily provided by giving the edge portion a sufficient depth, in particular more than 3 cm.

Wenn der Hauptabschnitt der Abstellplatte in an sich bekannter Weise durch eine in einem Rahmen gefasste Glasplatte gebildet ist, kann der Rost vorteilhafterweise einteilig mit dem Rahmen ausgeführt sein.If the main portion of the storage tray is formed in a manner known per se by a glass plate gripped in a frame, the grate can advantageously be made in one piece with the frame.

Erfindungsgemäß weist der Rost schräggestellte Lamellen auf. Solche Lamellen können eine durch den Rost hindurchlaufende Luftströmung in seitlicher Richtung ablenken und so für einen ausreichenden Luftstrom durch ein von der Abstellplatte begrenztes Fach sorgen. Durch unterschiedliche Schrägstellungen über verschiedene Bereiche des Rostes hinweg wird die Kühlluft in Abhängigkeit der Kühlluftumwälzung in unterschiedliche Richtungen unterhalb der Abstellplatte oder zu ihrer Abstellfläche hin umgelenkt, so dass verschiedene Bereiche mit Kühlluft beaufschlagt werden. Hierbei kann die Kühlluftumwälzung statisch oder zwangsweise mittels Ventilator stattfinden.According to the invention, the grate has inclined slats. Such fins can deflect a passing through the grate air flow in the lateral direction, thus ensuring a sufficient flow of air through a bounded by the storage tray. Due to different inclinations over different areas of the grate, the cooling air is deflected as a function of the cooling air circulation in different directions below the storage tray or to its storage area, so that different areas are acted upon with cooling air. Here, the cooling air circulation can take place statically or forcibly by means of a fan.

Die Lamellen sind vorzugsweise im Querschnitt winkelförmig mit einem schrägen Schenkel zum Ablenken der Luftströmung und einem in Höhe der Oberseite der Platte liegenden horizontalen Schenkel, auf dem im Bedarfsfall Kühlgut abstellbar ist.The lamellae are preferably angular in cross-section with an oblique leg for deflecting the air flow and lying at the level of the top of the plate horizontal leg on which refrigerated goods can be deposited if necessary.

Um den Strömungswiderstand gering zu halten, ist der Winkel der Lamelle vorzugsweise ein stumpfer Winkel.In order to keep the flow resistance low, the angle of the blade is preferably an obtuse angle.

Vorzugsweise sind die Lamellen zum Hauptabschnitt hin abschüssig, um einem abwärts verlaufenden Luftstrom in einem unterhalb der Platte liegenden Fach eine seitliche Geschwindigkeitskomponente zu verleihen.Preferably, the fins are sloping toward the main portion to impart a lateral velocity component to a downwardly extending airflow in a compartment below the panel.

Um die Stabilität zu verbessern, sind die Lamellen vorzugsweise untereinander durch Stege verbunden.To improve the stability, the lamellae are preferably interconnected by webs.

Weitere Merkmale und Vorteile der Erfindung ergeben sich aus der nachfolgenden Beschreibung eines Ausführungsbeispiels unter Bezugnahme auf die beigefügten Figuren.Further features and advantages of the invention will become apparent from the following description of an embodiment with reference to the accompanying figures.

Die in Fig. 1 in perspektivischer Ansicht gezeigte Abstellplatte ist gegliedert in einen bei Montage der Abstellplatte 1 in einem Kältegerät vorn, d.h. nahe zur Tür, liegenden Hauptabschnitt 2 und einen hinten, benachbart zur Rückwand, liegenden Randabschnitt 3. Der Hauptabschnitt 2 ist gebildet durch eine Platte 4 aus Sicherheitsglas, die einteilig von einem Rahmen 5 aus Kunststoff umspritzt ist. In den Rahmen 5 können zur Versteifung nicht gezeigte Metallprofile eingebettet sein.In the Fig. 1 Shelf plate shown in a perspective view is divided into a when mounting the storage tray 1 in a refrigerator front, ie near the door, lying main section 2 and a rear, adjacent to the rear wall, lying edge portion 3. The main section 2 is formed by a plate 4 made of safety glass , which is molded in one piece by a frame 5 made of plastic. In the frame 5 can be embedded for stiffening metal profiles, not shown.

Der Randabschnitt 3 ist einteilig mit dem Rahmen 5 ausgeführt und umfasst eine Mehrzahl von Lamellen 6, die an ihren Enden durch Profile 7 verbunden sind, die die seitlichen Profile des Rahmens 5 fluchtend verlängern. An den rückwärtigen Enden der Profile 7 ist jeweils eine aufwärts geschwungene geringfügig elastische Zunge 8 geformt, die dazu dient, die Trägerplatte 1 in Nuten zu verrasten, die an den Seitenwänden eines Kältegeräte-Innenbehälters gebildet sind.The edge portion 3 is formed integrally with the frame 5 and comprises a plurality of fins 6, which are connected at their ends by profiles 7, which extend the side profiles of the frame 5 in alignment. At the rear ends of the profiles 7 each an upwardly curved slightly elastic tongue 8 is formed, which serves to lock the support plate 1 in grooves formed on the side walls of a refrigerator inner container.

Zwischen den Profilen 7 und parallel zu diesen sind die Lamellen 6 ferner durch eine Mehrzahl von Stegen 9 verbunden. Wie in Fig. 2 zu sehen, haben die Stege 9 einen oberen Rand 10, der jeweils zwischen zwei Lamellen 6 von vorn nach hinten, das heißt von rechts nach links in Fig. 2, abschüssig ist, so dass die Stege 9 in der Perspektive der Fig. 1 nicht sichtbar sind und auch ein Abwischen der Oberseite des Randabschnitts 3 nicht behindern.Between the profiles 7 and parallel to these, the fins 6 are further connected by a plurality of webs 9. As in Fig. 2 to see, the webs 9 have an upper edge 10, each between two slats 6 from front to back, that is from right to left in Fig. 2 , is sloping, so that the webs 9 in the perspective of Fig. 1 are not visible and not hinder wiping the top of the edge portion 3.

Die Lamellen 6 haben jeweils einen winkelförmigen Querschnitt mit einem horizontalen Schenkel 11, der mit der Oberseite des Rahmens 5 bündig ist, so dass die Lamellen 6 gemeinsam eine zum Abstellen von Kühlgut hinreichend ebene Stellfläche bilden. Schräge Schenkel 12 der Lamellen 6 sind jeweils nach vorn, das heißt nach rechts in Fig. 2, abschüssig, um einen abwärts gerichteten Luftstrom, der von oben auf die Lamellen 6 trifft, nach vorn abzulenken und so einen vorwärts gerichteten Luftstrom unterhalb der Trägerplatte 1 zu erzeugen. Gleichzeitig verleiht die Winkelform den Lamellen 6 eine hohe Tragfähigkeit bei geringem Materialeinsatz.The lamellae 6 each have an angular cross-section with a horizontal leg 11 which is flush with the top of the frame 5, so that the lamellae 6 together form a sufficient for parking of goods to be cooled flat surface. Beveled legs 12 of the fins 6 are each forward, that is to the right in Fig. 2 sloping down to deflect a downward stream of air impinging from the top of the lamellae 6 forward to create a forward flow of air beneath the support plate 1. At the same time, the angular shape gives the lamellae 6 a high load capacity with low use of material.

Fig. 3 veranschaulicht die Wirkungsweise der Erfindung anhand eines schematischen Schnittes durch ein No-Frost-Kältegerät mit einem Verdampfer 13, der in einer im oberen Bereich des Kältegerätegehäuses abgetrennten Kammer 14 untergebracht ist. Ein nicht dargestellter Ventilator saugt Luft aus dem Kühlraum 15 des Gerätes durch eine türnahe Einlassöffnung 16 in die Kammer 14, wo sie am Verdampfer 13 entlang streicht und gekühlt an einer zur Rückwand des Gehäuses benachbarten Auslassöffnung 17 wieder austritt. Der Kaltluftstrom fließt an der Rückwand des Gehäuses entlang und trifft dabei auf die Randabschnitte 3 von mehreren Trägerplatten 1, deren Lamellen den Luftstrom nach vorn ablenken. So fließt in jedem Fach 18 unterhalb einer der Trägerplatten 1 ein Teil des Luftstroms türwärts, und alle Fächer 18 werden gleichmäßig gekühlt. Zwischen den Vorderkanten der Trägerplatten 1 und an der Tür des Gerätes aufgehängten Türabstellern 19 fließt der Luftstrom nach oben, zurück zur Einlassöffnung 16. Fig. 3 illustrates the operation of the invention with reference to a schematic section through a no-frost refrigeration device with an evaporator 13, which is housed in a separated in the upper region of the refrigerator housing chamber 14. An unillustrated fan sucks air from the refrigerator 15 of the device through a door near inlet 16 into the chamber 14, where it sweeps along the evaporator 13 and cooled exits at an outlet opening 17 adjacent to the rear wall of the housing again. The cold air flow flows along the rear wall of the housing and strikes the edge portions 3 of a plurality of support plates 1, the fins deflect the air flow forward. Thus, in each compartment 18 below one of the carrier plates 1, part of the air flow flows in the direction of the door, and all compartments 18 are cooled uniformly. Between the leading edges of the carrier plates 1 and door cabinets 19 suspended on the door of the appliance, the air flow flows upwards, back to the inlet opening 16.

Die Randabschnitte 3 bieten dem Kaltluftstrom, wenn sie nicht mit Kühlgut verdeckt sind, eine große freie Querschnittsfläche, die dem Luftstrom nur wenig Widerstand entgegensetzt. Der Luftstrom ist daher nicht ernstlich behindert, wenn die Randabschnitte 3 auf einem beträchtlichen Teil ihrer Fläche mit Kühlgut vollgestellt sind.The edge portions 3 offer the cold air flow, if they are not covered with refrigerated goods, a large free cross-sectional area, which opposes the air flow only little resistance. The air flow is therefore not seriously hindered when the edge portions 3 are completed on a considerable part of their surface with refrigerated goods.
