Description

Die vorliegende Erfindung betrifft einen Kühlgutbehälter, insbesondere einen Auszugkasten, für ein Kältegerät, insbesondere für ein Haushaltskältegerät.The present invention relates to a refrigerated goods container, in particular a drawer, for a refrigerator, in particular for a household refrigerator.

Kühlgutbehälter von Kältegeräten, wie insbesondere Auszugkästen, haben oft beträchtliche Kantenlängen, und ihre Grundfläche kann der Grundfläche des Lagerraums des Kältegeräts oder der Hälfte davon entsprechen. Bei voller Beladung solch eines Kühlgutbehälters können somit erhebliche Kräfte auf die Grundfläche und die Seitenwände des Kühlgutbehälters einwirken. Um einem Kühlgutbehälter die für eine volle Beladung erforderliche Steifigkeit zu verleihen, sind daher unter Umständen beträchtliche Wandstärken und damit ein hoher Materialaufwand und Kosten verbunden. Ein hohes Gewicht macht einen solchen Kühlgutbehälter auch für den Benutzer unhandlich.Refrigerated goods containers of refrigeration appliances, in particular pull-out boxes, often have considerable edge lengths, and their base area can correspond to the base area of the storage space of the refrigeration appliance or half thereof. When fully loaded such a refrigerated goods so considerable forces can act on the base and the side walls of the refrigerated goods. To give a refrigerated goods required for a full load rigidity, therefore, under certain circumstances considerable wall thicknesses and thus a high cost of materials and costs are associated. A high weight makes such a refrigerated goods container also unwieldy for the user.

Die DE 10 2005 045325 A1 beschreibt einen Kühlgutbehälter für ein Kältegerät, mit einer von Wänden umgebenen Bodenplatte, in der sich nebeneinander erstreckende Wellenkämme und Wellentäler in zwei zueinander orthogonalen Richtungen geformt sind, so dass lokale Erhebungen und Senken gebildet sind, um ein Wegrollen vom Kühlgut zu verhindern. Es ist ferne eine Enlegeplatte zum Einlegen in den Kühlgutbehälter mit einem entsprechenden Höhenprofil vorgesehen. An den lokalen Senken sind hier jeweils Bohrungen in der Einlegeplatte gebildet, durch die Feuchtigkeit, die in eine der Senken fließt, in einen Zwischenraum zwischen der Einlegeplatte und der Bodenplatte gelangen kann.The DE 10 2005 045325 A1 describes a refrigerated goods container for a refrigerator, with a bottom plate surrounded by walls, in which adjacent wave crests and troughs are formed in two mutually orthogonal directions, so that local elevations and depressions are formed to prevent rolling away from the refrigerated goods. It is far away a fitting plate for insertion into the refrigerated goods provided with a corresponding height profile. Holes in the insert plate are formed here at the local sinks, through which moisture which flows into one of the depressions can enter a space between the insert plate and the bottom plate.

Aus der JP 64 041084 U ist ein Kühlgutbehälter bekannt, an dessen zur Mitte abfallenden Boden sich zur Mitte des Bodens vom Boden erhebende im Wesentlichen parallel zueinander verlaufende Stege angeordnet sind. Die Stege weisen im Bereich um die Mitte des Bodens Unterbrechungen auf.From the JP 64 041084 U is a refrigerated goods known, are arranged at the bottom sloping to the center to the center of the soil from the ground uplifting substantially mutually parallel webs. The webs have in the area around the center of the floor interruptions.

In der JP 54 074363 U wird ein Kühlgutbehälter beschrieben, der einen mit sich längs erstreckenden Rillen versehenen Boden Aufweist. Die Rillen weisen eine senkenartige Unterbrechung auf.In the JP 54 074363 U a refrigerated goods container is described which has a longitudinally extending grooves provided bottom. The grooves have a sink-like interruption.

Die JP 52 149458 U beschreibt einen Kühlgutbehälter, der einen Boden mit lang gestreckten Mulden aufweist. Die Mulden sind auf ein Flüssigkeitsablaufloch im Boden zu abschüssig ausgeführt.
Aufgabe der Erfindung ist, einen verbesserten, kostengünstigen Kühlgutbehälter für ein Kältegerät zu schaffen.
Unter Kältegerät wird hier insbesondere ein Haushaltskältegerät verstanden, das heißt ein Kältegerät, das zur Haushaltsführung eingesetzt wird, wie beispielsweise ein Kühlschrank, oder eine Kühlgefrierkombination. Unter Kühlgutbehälter wird hier insbesondere ein Auszugskasten des Kältegeräts verstanden, wie beispielsweise eine Feuchteschale oder ein Obst- oder Gemüsebehälter. Solch ein Kühlgutbehälter kann geschlossen ausgebildet sein, so dass im Inneren des Kühlgutbehälters ein feuchteres Mikroklima aufrecht erhalten werden kann, als insbesondere in dem Lagerraum des Kältegeräts, in dem der Kühlgutbehälter angeordnet ist.
Die Aufgabe wird gelöst, indem bei einem Kühlgutbehälter, insbesondere einem Auszugkasten, für ein Kältegerät, insbesondere für ein Haushaltskältegerät, mit einer von Wänden umgebenen Bodenplatte, in der sich nebeneinander erstreckende Wellenkämme und Wellentäler geformt sind, die Bodenplatte in einem entlang einem Wellental verlaufenden Querschnitt von einem Scheitelpunkt aus in zwei Richtungen abschüssig ist. Das Wellental bildet somit eine Ablaufrinne für Feuchtigkeit. Der abschüssige Verlauf des Wellentals bewirkt, dass vom Kühlgut eventuell abgesondertes Wasser in dem Wellental nicht stehen bleibt, sondern seitwärts abfließt und dadurch von auf den Wellenkämmen aufliegenden Kühlgut fern gehalten wird. Staunässe an dem Kühlgut wird somit vermieden und die Haltbarkeit des Kühlguts dadurch erhöht. Darüber hinaus bewirkt im Falle des in zwei Richtungen abschüssigen Wellentals dessen längsgekrümmte oder längsgeknickte Form auch eine Torsionsversteifung, die den herkömmlichen Kühlgutbehältern mit gewelltem Boden fehlt.The JP 52 149458 U describes a refrigerated goods container having a bottom with elongated troughs. The troughs are designed to run down a liquid drain hole in the ground.
The object of the invention is to provide an improved, inexpensive Kühlgutbehälter for a refrigerator.
Under refrigeration device is in particular a household refrigeration appliance understood, that is, a refrigerator that is used for household management, such as a refrigerator, or a Kühlgefrierkombination. Under refrigerated goods is understood here in particular a pull-out box of the refrigerator, such as a moisture bowl or a fruit or vegetable container. Such a refrigerated goods container may be designed to be closed, so that a more humid microclimate can be maintained in the interior of the refrigerated goods container than, in particular, in the storage space of the refrigeration appliance in which the refrigerated goods container is arranged.
The object is achieved by providing a refrigerated goods container, in particular a pull-out box, for a refrigeration appliance, in particular for a domestic refrigeration appliance, with a bottom plate surrounded by walls, in which wave crests and wave troughs extending next to one another are formed, the bottom plate in a cross section running along a wave trough from one vertex downhill in two directions. The wave trough thus forms a gutter for moisture. The sloping course of the wave trough causes the chilled goods eventually Separate water does not stop in the trough, but flows sideways and is kept away from it by refrigerated goods resting on the wave crests. Waterlogging on the refrigerated goods is thus avoided and the durability of the refrigerated goods thereby increased. In addition, in the case of the bifurcated wave trough in two directions, its longitudinally curved or longitudinally buckled shape also causes a torsional stiffener which is lacking in the conventional corrugated containers with corrugated bottom.

Indem der Boden des Behälters im Bereich der Wellentäler bombiert ausgeführt wird, das heißt die Bodenplatte des Behälters weist entlang der Wellentäler eine sphärische Krümmung mit konvexer Oberseite auf, wird die Steifigkeit des Kühlgutbehälters verbessert. Die Versteifungswirkung nimmt mit der Stärke der Bombierung zu.By the bottom of the container is executed cambered in the region of the troughs, that is, the bottom plate of the container has a spherical curvature along the troughs with a convex top, the rigidity of the refrigerated goods is improved. The stiffening effect increases with the strength of the crowning.

Ein Kühlgutbehälter von hoher Steifigkeit kann auch erhalten werden, indem bei einem Kühlgutbehälter mit einer von Wänden umgebenen Bodenplatte, in der sich nebeneinander erstreckende Wellenkämme und Wellentäler geformt sind, insbesondere bei einem Kühlgutbehälter vom im vorhergehenden Absatz definierten Typ, die Höhendifferenz zwischen Wellenkämmen und Wellentälern in derjenigen von zwei quer zu den Wellenkämmen und Wellentälern orientierten Schnittebenen größer ist, die weiter von einer Mittelebene des Kühlgutbehälters entfernt ist. Die Versteifungswirkung der Wellenkämme und Wellentäler nimmt dadurch mit wachsender Entfernung von der Mitte der Bodenplatte zu, das heißt die Bodenplatte ist dort am wirksamsten versteift, wo die Versteifung am meisten benötigt wird.A refrigerated goods container of high rigidity can also be obtained by forming the height difference between wave crests and wave troughs in a refrigerated goods container having a bottom plate surrounded by walls, in which wave crests and wave troughs are formed side by side, particularly in a refrigerated goods container of the type defined in the previous paragraph that of two transverse to the wave crests and troughs oriented cutting planes is greater, which is farther away from a median plane of the refrigerated goods. The stiffening effect of the wave crests and troughs thereby increases with increasing distance from the center of the bottom plate, that is, the bottom plate is most effectively stiffened where the stiffening is most needed.

Im einen wie im anderen Fall ist bevorzugt, dass die Wellenkämme horizontal verlaufen und damit eine ebene Auflagefläche für das Kühlgut bilden. Auf diese Weise wird ein Verrutschen des auf den Wellenkämmen aufliegenden Kühlguts und ein Kontakt mit der in den Wellentälern ablaufenden Flüssigkeit vermieden.In one case, as in the other case, it is preferred that the wave crests extend horizontally and thus form a flat support surface for the chilled goods. In this way, slippage of the cooling agent resting on the wave crests and contact with the liquid running in the wave troughs is avoided.

Simulationsrechnungen haben gezeigt, dass eine besonders wirksame Versteifung bei einem Verhältnis zwischen dem Abstand benachbarter Wellentäler oder Wellenkämme zur Höhendifferenz zwischen Wellenkamm und Wellental von ca. 3:1 erreicht wird.Simulation calculations have shown that a particularly effective stiffening is achieved at a ratio between the distance between adjacent troughs or wave crests to the height difference between the wave crest and trough of about 3: 1.

Des weiteren wurde festgestellt, dass eine besonders wirksame Versteifung erreichbar ist, wenn die Bodenplatte anstelle etwa eines kreisbogenförmigen Querschnitts wenigstens lokal einen parabelförmigen Querschnitt aufweist. Ein solcher parabelförmiger Querschnitt kann in einer entlang einem Wellental verlaufenden Schnittebene gebildet sein; er kann sich aber auch in einer quer zu den Wellentälern und Wellenkämmen verlaufenden Schnittebene jeweils beiderseits eines Wellenkamms oder eines Wellentals erstrecken. Insbesondere weisen die Wellentäler einen parabelförmigen Querschnitt auf.Furthermore, it has been found that a particularly effective stiffening can be achieved if the bottom plate instead of about a circular arc-shaped cross section at least locally has a parabolic cross-section. Such a parabolic cross-section may be formed in a section plane running along a wave valley; but it can also extend in a direction transverse to the troughs and wave crests cutting plane each side of a wave crest or a wave trough. In particular, the troughs have a parabolic cross-section.

Um eventuell ablaufende Flüssigkeiten aufzufangen, weist die Bodenplatte vorzugsweise einen Graben auf, der sich wenigstens zwischen Längsenden der Wellenkämme und diesen benachbarten Wänden des Kühlgutbehälters erstreckt.In order to catch any liquids that may run off, the bottom plate preferably has a trench which extends at least between longitudinal ends of the wave crests and these adjacent walls of the refrigerated goods container.

Besonders bevorzugt ist, dass die Wellenkämme und Wellentäler in einem zentralen Bereich der Bodenplatte geformt sind und der zentrale Bereich von dem Graben rings umgeben ist.It is particularly preferred that the wave crests and wave troughs are formed in a central region of the bottom plate and the central region is surrounded by the trench rings.

Der Graben sollte nicht höher liegen als die Längsenden der Wellentäler, um einen freien Abfluss von Flüssigkeit aus den Wellentälern in den Graben zu gewährleisten.The trench should not be higher than the longitudinal ends of the troughs to ensure a free drainage of liquid from the troughs in the trench.

Further features and advantages of the invention will become apparent from the following description of embodiments with reference to the accompanying figures. Show it:

Ein erfindungsgemäßer Kühlgutbehälter 1 in Form eines Auszugkastens ist in Fig. 1 in Längsrichtung halbiert dargestellt, um einen Querschnitt durch eine Bodenplatte 2 des Kühlgutbehälters 1 zeigen zu können. Die Schnittebene ist gleichzeitig eine Symmetrieebene des Kühlgutbehälters 1. Eine Vorderwand 3 des Kühlgutbehälters 1, die, wenn der Kühlgutbehälter 1 in einem Kältegerät eingebaut ist, dessen Tür zugewandt ist, ist in der Fig. 1 vom Betrachter abgewandt. Eine Rückwand 4 des Kühlgutbehälters hat einen gestuften Verlauf, mit einem nach vorn verschobenen zentralen Abschnitt 5, um die Steifigkeit zu erhöhen. An einer vom Betrachter abgewandten Seite einer Seitenwand 6 können Konturen zur Befestigung des Kühlgutbehälters 1 an einem Teleskopauszug oder dergleichen vorgesehen sein.
Ein zentraler Bereich 7 der Bodenplatte 2 ist ausgefüllt von Wellenkämmen 8 und Wellentälern 9, die sich jeweils parallel zu Vorderwand 3 und Rückwand 4 erstrecken. Es ist allerdings auch möglich, die Bodenplatte 2 derart auszubilden, dass sich die Wellenkämme 8 und Wellentäler 9 parallel zu den Seitenwänden 6 erstrecken. Die Wellenkämme 8 verlaufen horizontal und bilden dadurch eine ebene Auflagefläche für einzulagerndes Kühlgut, wie beispielsweise Obst und Gemüse. Die Wellentäler 9 sind von der mittig durch den Kühlgutbehälter 1 verlaufenden Schnittlinie aus zu den beiden Seitenwänden 6 hin abschüssig ausgebildet, so dass Feuchtigkeit, die eventuell vom Kühlgut abgesondert wird und in die Wellentäler 9 sickert, entlang der Wellentäler 9 zu den Seitenwänden 6 hin ablaufen kann.
Rings um den zentralen Bereich 7 der Bodenplatte 2 verläuft ein Graben 10, in dem sich die Feuchtigkeit sammeln kann, die entlang der Wellentäler 9 abläuft. Aufgrund der Lage des Grabens 10 am Fuß der vertikalen Wände 3, 4, 6 kann nur sehr kleinteiliges Kühlgut in Kontakt mit Flüssigkeit in dem Graben 10 kommen.
Fig. 2 zeigt einen Querschnitt durch den halbierten Kühlgutbehälter 1, von der als strichpunktierte Linie dargestellten Längsmittelebene des Kühlgutbehälters 1 bis zu einer der Seitenwände 6. Die Schnittebene der Fig. 2 verläuft am Boden eines Wellentals 9, und die von der Schnittebene zu beiden Seitenwänden 6 abschüssige Wölbung des Bodenverlaufs sowie die horizontale Ausrichtung der Wellenkämme 8 ist deutlich zu erkennen. Das Wellental 9 beschreibt im Schnitt der Fig. 2 von einer der Seitenwände 6 zu der gegenüberliegenden Seitenwand 6 hin einen bombierten Verlauf, wobei das Maximum bei der Längsmittelebene liegt. Es sind aber auch andere Ausgestaltungen der Wellentäler 9 möglich, wie beispielsweise die Lage des Maximums im Bereich einer der Seitenwände 6 oder eine von der Längsmittelebene zu den Seitenwänden 6 hin linear abschüssige Form.An inventive refrigerated goods container 1 in the form of a pull-out box is in Fig. 1 shown in half in the longitudinal direction to show a cross section through a bottom plate 2 of the refrigerated goods 1. The cutting plane is at the same time a plane of symmetry of the refrigerated goods container 1. A front wall 3 of the refrigerated goods container 1, which, when the refrigerated goods container 1 is installed in a refrigeration device, the door is facing, is in the Fig. 1 turned away from the viewer. A rear wall 4 of the refrigerated goods has a stepped course, with a forward shifted central portion 5, to increase the rigidity. On a side facing away from the viewer side of a side wall 6 contours can be provided for attachment of the refrigerated goods container 1 to a telescopic extension or the like.
A central region 7 of the bottom plate 2 is filled by wave crests 8 and troughs 9, which each extend parallel to the front wall 3 and the rear wall 4. However, it is also possible to form the bottom plate 2 in such a way that the wave crests 8 and wave troughs 9 extend parallel to the side walls 6. The wave crests 8 extend horizontally and thereby form a flat bearing surface for refrigerated goods to be stored, such as fruits and vegetables. The wave troughs 9 are formed from the centrally extending through the refrigerated goods 1 section line to the two side walls 6 down, so that moisture that is possibly segregated from the refrigerated goods and seeping into the troughs 9, along the wave troughs 9 to the side walls 6 run out can.
Around the central region 7 of the bottom plate 2, a trench 10 extends, in which the moisture can accumulate, which runs along the troughs 9. Due to the position of the trench 10 at the foot of the vertical walls 3, 4, 6 only very small-sized refrigerated goods can come into contact with liquid in the trench 10.
Fig. 2 shows a cross section through the halved refrigerated goods container 1, from the longitudinal center plane of the refrigerated goods container 1 shown as a dotted line to one of the side walls 6. The sectional plane of the Fig. 2 runs at the bottom of a wave trough 9, and the sloping from the cutting plane to both side walls 6 curvature of the soil course and the horizontal orientation of the wave crests 8 can be clearly seen. The wave trough 9 describes in section the Fig. 2 from one of the side walls 6 to the opposite side wall 6 towards a cambered course, wherein the maximum is located at the longitudinal center plane. But there are also other embodiments of the wave troughs 9 possible, such as the position of the maximum in the region of one of the side walls 6 or from the longitudinal center plane to the side walls 6 out linearly sloping shape.

Der Höhenunterschied zwischen Wellenkämmen 8 und Wellentälern 9 variiert deutlich je nach Lage einer Schnittebene, in der er gemessen wird. Der niedrigste Wert h0 des Höhenunterschieds ist an der Längsmittelebene des Kühlgutbehälters 1 zu beobachten, die gleichzeitig die Schnittebene der Fig. 1 ist. Mit zunehmender Entfernung von dieser Längsmittelebene nimmt die Höhendifferenz kontinuierlich zu und erreicht ihr Maximum h1 an einer Ebene 13, benachbart zu steil zum Graben 10 abfallenden Stirnflächen 14, die die Enden der Wellenkämme 8 bilden.
Für eine ideale Versteifungswirkung sollte der Abstand D zwischen zwei benachbarten Wellenkämmen 8 oder Wellentälern 9 vorzugsweise dreimal so groß sein wie die Höhendifferenz. Da hier die Wellenkämme 8 und Wellentäler 9 parallel sind und die Höhendifferenz entlang der Wellentäler zwischen h0 und h1 veränderlich, variiert auch das Verhältnis zwischen dem Abstand D und der Höhendifferenz in Breitenrichtung des Kühlgutbehälters 1 um den Wert 3.
Wie in der frontalen Ansicht der Fig. 3 gezeigt, setzt sich der zentrale Bereich 7 im Längsschnitt aus einer Vielzahl von jeweils alternierend gekrümmten, jeweils den Wellenkämmen 8 beziehungsweise Wellentälern 9 entsprechenden Parabelbögen zusammen, deren Steigung immer an Schnittpunkten 11 am höchsten ist, an denen ein Parabelbogen eines Wellenkamms 8 mit einem Parabelbogen eines Wellentals 9 aneinander stößt. Der Winkel, den die Oberseite der Bodenplatte 2 an diesen Schnittpunkten 11 mit der Vertikalen bildet, variiert von α0 = ca. 45° an der Längsmittelebene bis α1 = ca. 30° an den Enden der Wellenkämme 8. Die Krümmungsradien der Wellentäler 9 kann von den Krümmungsradien der Wellenkämme 8 verschieden gewählt sein. Insbesondere sind die Krümmungsradien der Wellenkämme 8 größer als die Krümmungsradien der Wellentäler 9 gewählt, so dass Druckstellen am Kühlgut vermieden werden.The height difference between wave crests 8 and troughs 9 varies significantly depending on the location of a sectional plane in which it is measured. The lowest value h0 of the height difference can be observed at the longitudinal center plane of the refrigerated goods container 1, which at the same time the sectional plane of the Fig. 1 is. As the distance from this longitudinal center plane increases, the height difference increases continuously and reaches its maximum h1 at a plane 13, adjacent to steeply sloping end faces 14 forming the ends of the wave crests 8.
For an ideal stiffening effect, the distance D between two adjacent wave crests 8 or troughs 9 should preferably be three times as large as the height difference. Since the wave crests 8 and wave troughs 9 are parallel here and the height difference along the wave troughs between h0 and h1 varies, the ratio between the distance D and the height difference in the width direction of the refrigerated goods container 1 also varies by the value 3.
As in the frontal view of the Fig. 3 shown, the central region 7 is composed in longitudinal section of a plurality of each alternately curved, respectively the wave crests 8 and troughs 9 corresponding parabolic arcs whose slope is always highest at intersections 11, where a parabola of a wave crest 8 with a parabola of a Wellentals 9 abuts each other. The angle formed by the top of the bottom plate 2 at these intersections 11 with the vertical varies from α 0 = about 45 ° at the longitudinal center plane to α 1 = about 30 ° at the ends of the wave crests 8. The radii of curvature of the troughs. 9 may be chosen differently from the radii of curvature of the wave crests 8. In particular, the radii of curvature of the wave crests 8 are selected larger than the radii of curvature of the wave troughs 9, so that pressure points on the refrigerated goods are avoided.

Claims (10)

  1. Container for refrigerated products (1), in particular a drawer, for a refrigeration appliance, having a base plate (2) surrounded by walls (3, 4, 6), in which base plate wave crests (8) and wave troughs (9) extending adjacent to one another are formed, characterised in that the base plate (2) slopes from an apex point in two directions in a cross section extending along a wave trough (9), so that the wave trough (9) forms a drainage channel for moisture, which is embodied to discharge the moisture laterally out of the wave trough (9).
  2. Container for refrigerated products according to claim 1, characterised in that the difference in height (h0, h1) between the wave crests (8) and wave troughs (9) is greater in that of the two cutting planes (13) oriented transversely to the wave crests (8) and the wave troughs (9), which is further removed from a longitudinal centre plane (12) of the container for refrigerated products.
  3. Container for refrigerated products according to one of the preceding claims, characterised in that the wave crests (8) extend horizontally such that a planar bearing surface is formed thereby.
  4. Container for refrigerated products according to one of the preceding claims, characterised in that in at least one cutting plane oriented transversely to the wave crests (8) and wave troughs (9), the ratio is 3:1 between the spacing of two adjacent wave troughs (9) or wave crests (8) and the difference in height between the wave crest (8) and wave trough (9).
  5. Container for refrigerated products according to one of the preceding claims, characterised in that the base plate (2) at least locally has a parabolic cross section.
  6. Container for refrigerated products according to claim 5, characterised in that the parabolic cross section is formed in a cutting plane extending along a wave trough (9).
  7. Container for refrigerated products according to claim 5, characterised in that the parabolic cross section extends in a cutting plane extending transversely to the wave troughs (9) and wave crests (8) on both sides of a wave crest (8) or a wave trough (9).
  8. Container for refrigerated products according to one of the preceding claims, characterised in that the base plate (2) has a groove (10) which extends at least between front faces (14) of the wave crests (8) and walls (6) of the container for refrigerated products (1) adjacent thereto.
  9. Container for refrigerated products according to claim 8, characterised in that the wave crests (8) and wave troughs (9) are formed in a central region (7) of the base plate (2) and in that the central region (7) is surrounded all around by the groove (10).
  10. Container for refrigerated products according to claim 8 or 9, characterised in that the groove (10) is not located higher than the longitudinal ends of the wave troughs (9).
