Description

Auszugkasten für ein Kältegerät Pull-out box for a refrigeration unit
Die vorliegende Erfindung betrifft einen Auszugkasten für ein Kältegerät. Auszugkästen werden häufig in einem durch einen Zwischenboden abgeteilten Fach des Innenraums von Kühlschränken eingesetzt, um dort wasserhaltiges Kühlgut wie insbesondere Obst zu oder Gemüse zu lagern, das bei ungeschützter Lagerung in dem Innenraum schnell Feuchtigkeit abgeben würde. Eine solche Feuchtigkeitsabgabe ist unerwünscht, da sie die Qualität des Kühlguts beeinträchtigt und die Feuchtigkeit am Verdampfer des Kältegeräts kondensiert, von wo sie unter Energieaufwand wieder beseitigt werden muss.The present invention relates to a drawer for a refrigeration device. Pull-out boxes are often used in a divided by an intermediate shelf compartment of the interior of refrigerators to store there hydrated refrigerated goods such as fruit or vegetables in particular, which would quickly release moisture in unprotected storage in the interior. Such a moisture release is undesirable because it affects the quality of the refrigerated goods and condenses the moisture at the evaporator of the refrigerator, from where it must be eliminated with energy expenditure again.
Die Unterbringung von derartigem Kühlgut in einem abgetrennten Volumen, wie es durch den Auszugkasten und gegebenenfalls den Zwischenboden geschaffen wird, führt jedoch dazu, dass die von dem Kühlgut unvermeidlicherweise abgegebene Feuchtigkeit aus dem Auszugkasten nur schlecht entweichen kann. So kann sich freies Wasser an Kontaktflächen gelagerter Früchte untereinander und mit dem Auszugkasten sammeln und einen Nährboden für Bakterien und Schimmelpilze bilden, was ebenfalls Qualität und Haltbarkeit des Kühlguts beeinträchtigt. Um mit dem entgegenzuwirken, muss der Auszugkasten häufig gereinigt werden.The accommodation of such refrigerated goods in a separate volume, as created by the drawer and, where appropriate, the false floor, however, means that the inevitable emitted by the refrigerated goods moisture from the drawer can escape only poorly. Thus, free water can collect on contact surfaces of stored fruit with each other and with the pull-out box and form a breeding ground for bacteria and mold, which also affects the quality and durability of the goods. To counteract this, the drawer must be cleaned frequently.
Um den Reinigungsprozess zu vereinfachen und die Zeitspanne zwischen zwei Reinigungsvorgängen zu verlängern, legen viele Benutzer den Boden eines solchenTo simplify the cleaning process and extend the time between two cleanings, many users set the floor of one

Although the paper helps to remove moisture from the immediate contact zone of the fruit with the bottom of the pull-out box, the

Hilfe eines solchen Papiers zu verhindern, dass empfindliche Früchte sich gegenseitig berühren.Help such a paper to prevent sensitive fruits from touching each other.
Um die Ansammlung von Feuchtigkeit zwischen einer Ablageplatte eines Auszugkastens und auf dieser Ablageplatte gelagertem Kühlgut zu verhindern, wurde in DE 203 13 431 U1 vorgeschlagen, den Boden einer solchen Ablageplatte mit Belüftungslöchern zu versehen und die von dem Kühlgut berührte Oberseite der Trageplatte mit einer Riffelung zu versehen. An Stelle einer großen zusammenhängenden Kontaktfläche zwischen Kühlgut und Ablageplatte werden so viele kleine Kontaktflächen geschaffen, die jeweils durch Vertiefungen der Riffelung voneinander getrennt sind. Durch die Vertiefungen der Riffelung kann zwar Luft an die Unterseite des Kühlguts gelangen, doch ist der Luftaustausch gering, sodass die Wirkung begrenzt ist. Die Riffelung kann auch nicht verhindern, dass Früchte beim Bewegen des Auszugkastens ins Rollen geraten und gegeneinander oder die Kastenwände stoßen bzw. in einen engen Kontakt miteinander oder den Kastenwänden geraten.In order to prevent the accumulation of moisture between a tray of an extension box and refrigerated goods stored on this tray, was proposed in DE 203 13 431 U1 to provide the bottom of such a tray with ventilation holes and touched by the refrigerated goods top of the support plate with a corrugation Mistake. Instead of a large contiguous contact surface between the goods to be cooled and shelf so many small contact surfaces are created, each by Wells of corrugation are separated. Although the recesses in the corrugation allow air to reach the underside of the chilled goods, the air exchange is low and the effect is limited. The corrugation can not prevent that fruit when moving the pull-out box rolling and collide against each other or the box walls or get into close contact with each other or the box walls.
In JP 2000180043 wird vorgeschlagen, eine Ablageplatte eines Auszugkastens mit einer Schutzfolie aus elastischem Material zu bedecken, die mit einer Vielzahl von hohlen Erhebungen versehen ist. Unter dem Gewicht einer darauf gelegten Frucht werden die Erhebungen flach gedrückt, wodurch vermieden wird, dass die Früchte beim Herausziehen und Einschieben des Auszugkastens wegrollen und aneinander stoßen. So ist es möglich, die Früchte dauerhaft so zu platzieren, dass sie einander nicht berühren. Im Gegenzug jedoch entsteht durch die flexible Folie eine sehr große Kontaktfläche an der Unterseite der Früchte, die für ihre Haltbarkeit wiederum nicht förderlich ist. Außerdem ist es mühsam, die flexible Folie zu reinigen, da sie nicht wie ein Geschirrteil in eine Spülmaschine gestellt werden kann.In JP 2000180043 it is proposed to cover a tray of an extraction box with a protective film of elastic material, which is provided with a plurality of hollow elevations. Under the weight of a fruit placed on it, the elevations are pressed flat, which prevents the fruits from rolling away and colliding when the pull-out box is pulled out and inserted. So it is possible to place the fruits permanently so that they do not touch each other. In return, however, creates a very large contact surface on the underside of the fruits by the flexible film, which in turn is not conducive to their durability. In addition, it is difficult to clean the flexible film because it can not be placed like a piece of dishes in a dishwasher.
Aufgabe der vorliegenden Erfindung ist, einen Auszugkasten für ein Kältegerät zu schaffen, der empfindliches Kühlgut wirksam vor Verderb schützt, einfach zu reinigen ist und mit geringem Materialaufwand einfach herstellbar ist.Object of the present invention is to provide a drawer for a refrigeration device that protects sensitive refrigerated goods effectively from spoiling, is easy to clean and is easy to produce with low material costs.
Die Aufgabe wird gelöst durch einen Auszugkasten mit den Merkmalen des Anspruchs 1. Indem die Erhebungen hart gemacht sind, vergrößern sie nicht durch eigene Verformung die Kontaktfläche zwischen sich und darauf abgelegtem Kühlgut. Um Früchte oder runde Behälter gegen Wegrollen zusichern, müssen die Abmessungen der Erhebungen und/oder ihre Abstände voneinander in horizontaler Richtung von ähnlicher Größenordnung wie die Abmessungen des darauf zu lagernden Kühlguts sein. Eine solche Höhenstruktur nur an der Oberseite der Ablageplatte zu bilden, würde einen hohen Materialaufwand erfordern und fertigungstechnische Schwierigkeiten aufwerfen, weswegen zu den Erhebungen komplementäre Aussparungen an der Unterseite der Trageplatte vorgesehen sind. Einer ersten Ausgestaltung zufolge ist die Ablageplatte entfernbar auf einer Bodenplatte des Auszugkasten platziert.The object is achieved by a drawer with the features of claim 1. By the surveys are made hard, they do not increase by their own deformation, the contact surface between it and stored refrigerated goods. To assure fruit or round containers from rolling away, the dimensions of the elevations and / or their distances from each other in the horizontal direction must be of a similar order of magnitude as the dimensions of the refrigerated goods to be stored thereon. To form such a height structure only at the top of the tray, would require a high cost of materials and create manufacturing difficulties, which is why the surveys complementary recesses are provided on the underside of the support plate. According to a first embodiment, the tray is removably placed on a bottom plate of the drawer.
In diesem Fall ist die Ablageplatte vorzugsweise zwischen den Erhebungen mit Bohrungen versehen, durch die an der Oberseite der Ablageplatte gesammelte Flüssigkeit in einem Zwischenraum zwischen der Bodenplatte und der Ablageplatte abfließen kann, der wenigstens durch die komplementären Aussparungen gebildet ist.In this case, the tray is preferably provided between the projections with holes through which liquid collected at the top of the tray can flow in a space between the bottom plate and the tray formed at least by the complementary recesses.
Einer zweiten Ausgestaltung zufolge ist die Ablageplatte selbst Bodenplatte des Auszugkastens.According to a second embodiment, the shelf itself is the bottom plate of the pull-out box.
Die Erhebungen sind vorzugsweise in einem periodischen Muster angeordnet.The bumps are preferably arranged in a periodic pattern.
Bei den Erhebungen kann es sich um lang gestreckte Rippen handeln.The surveys may be elongated ribs.
Diese Rippen sind vorzugsweise von den Wänden des Auszugkastens durch einen Graben getrennt. Ein solcher Graben erleichtert die Reinigung der Ablageplatte, da Feuchtigkeit oder Schmutz, der sich zwischen den Erhebungen gesammelt hat, in den Graben gewischt und von dort entfernt werden kann.These ribs are preferably separated from the walls of the pull-out box by a trench. Such a trench facilitates cleaning of the tray, since moisture or dirt that has accumulated between the ridges can be wiped into the trench and removed therefrom.
Um gegebenenfalls auch ein Abfließen von Flüssigkeit zu ermöglichen, liegt der Graben vorzugsweise tiefer als sich zwischen den Rippen erstreckende Rillen.In order to possibly also allow a drainage of liquid, the trench is preferably deeper than between the ribs extending grooves.
Die Rippen sind vorzugsweise in Breitenrichtung oder in Tiefenrichtung des Auszugkastens gestaffelt, um eine Platz sparende Lagerung von walzenförmigem Kühlgut zu ermöglichen.The ribs are preferably staggered in the width direction or in the depth direction of the pull-out box in order to allow a space-saving storage of roller-shaped refrigerated goods.
Die Rippen können zwar Kühlgut von walzenförmiger Gestalt an Wegrollen hindern, nicht aber solches von kugeliger Gestalt. Um dies zu erreichen, weist die Ablageplatte in aufeinanderfolgenden parallelen Schnittebenen vorzugsweise einen gewellten Querschnitt mit schwankendem mittleren Niveau oder mit schwankender Amplitude der Wellen auf. - A -Although the ribs can prevent refrigerated goods of cylindrical shape from rolling away, but not such spherical shape. To achieve this, the tray in successive parallel cutting planes preferably has a corrugated cross-section with a fluctuating average level or with varying amplitude of the waves. - A -
Selbstverständlich dürfen die Erhebungen keine scharfen Kanten aufweisen, um nicht ihrerseits empfindliches Kühlgut zu beschädigen. Um empfindliches Kühlgut zu schonen, haben die Rippen vorzugsweise Krümmungsradien von nicht weniger als 1 cm.Of course, the surveys must not have sharp edges, so as not to damage sensitive refrigerated goods. In order to preserve sensitive refrigerated goods, the ribs preferably have radii of curvature of not less than 1 cm.

Fig. 1 zeigt eine perspektivische Ansicht eines aus einem glasklaren Kunststoff im Spritzguss gefertigten Auszugkastens gemäß einer ersten Ausgestaltung der Erfindung. Der Kasten hat eine Bodenplatte 1 , die von vertikalen Wänden 2, 3, 4, 5 umgeben ist. An einer Kante, an der die vordere Wand 2 und die Bodenplatte 1 aneinander stoßen, ist eine lang gestreckte Griffnische 6 gebildet. In der Bodenplatte 1 ist eine Vielzahl von im Querschnitt gleichmäßig geschwungenen Rippen 7 gebildet. Die Rippen 7 erstrecken sich parallel in Tiefenrichtung der Bodenplatte 1. Die Kämme von benachbarten Rippen 7 haben einen Abstand von zwischen 1 und 5 cm, und der Höhenunterschied zwischen den Kämmen und der tiefsten Stelle einer Rille 8 zwischen zwei Rippen 7 beiträgt mehrere mm. Rippenabstand und Höhenunterschied sind so aneinander angepasst, dass ein runder Gegenstand 9 von mehreren cm Durchmesser wie etwa eine liegende Flasche, ein Apfel oder eine Tomate, zwei benachbarte Rippen 7 in der Nähe von deren Kämmen berührt, nicht aber den Boden der Rille 8 zwischen den Rippen 7. So bleibt die Kontaktfläche zwischen dem Gegenstand 9 und der Bodenplatte 1 klein, und Feuchtigkeit kann von den Rillen 8 aufgenommen werden, ohne mit dem Gegenstand 9 in Kontakt zu geraten.1 shows a perspective view of an extractable box made of a clear plastic in an injection molding according to a first embodiment of the invention. The box has a bottom plate 1 which is surrounded by vertical walls 2, 3, 4, 5. At an edge at which the front wall 2 and the bottom plate 1 abut each other, an elongated handle niche 6 is formed. In the bottom plate 1, a plurality of uniformly curved in cross-section ribs 7 is formed. The ribs 7 extend parallel in the depth direction of the bottom plate 1. The ridges of adjacent ribs 7 are spaced from each other between 1 and 5 cm, and the height difference between the crests and the lowest point of a groove 8 between two ribs 7 contributes several mm. Rib spacing and height difference are adapted to one another such that a round article 9 of several cm diameter, such as a lying bottle, an apple or a tomato, touches two adjacent ribs 7 near their crests, but not the bottom of the groove 8 between them Ribs 7. Thus, the contact area between the article 9 and the bottom plate 1 remains small, and moisture can be absorbed by the grooves 8 without coming into contact with the article 9.
In dem gezeigten Ausführungsbeispiel haben die Rippen 7 einen Querschnitt in Form eines Kreisbogens mit nach oben gerichteter konvexer Seite, d. h. mit Krümmungsmittelpunkt unterhalb der Bodenplatte 1. Die Rillen 8 hingegen sind durch nach oben konkave Kreisbögen mit dem gleichen Krümmungsradius r wie die Rippen 7 gebildet.In the embodiment shown, the ribs 7 have a cross section in the form of a circular arc with upward convex side, d. H. with the center of curvature below the bottom plate 1. The grooves 8, however, are formed by upwardly concave circular arcs with the same radius of curvature r as the ribs 7.
Selbstverständlich können die Krümmungsradien von Rippen 7 und Rillen 8 sich unterscheiden. So kann es z. B. wünschenswert sein, den Rillen einen kleinerenOf course, the radii of curvature of ribs 7 and grooves 8 may differ. So it may be z. B. be desirable, the grooves a smaller
Krümmungsradius als den Rippe, um zu verhindern, dass kleinteiliges Kühlgut, z.B. Trauben, den Boden der Rillen berührt. Es kann auch der Krümmungsradius über den Querschnitt einer Rippe hinweg variieren. Er sollte jedoch nicht zu klein gewählt sein, vorzugsweise nicht kleiner als ein Zentimeter, um zu verhindern, dass die Rippen 7 sich in empfindliches Kühlgut eindrücken.Radius of curvature as the rib, to prevent small-sized refrigerated goods, e.g. Grapes touched the bottom of the grooves. The radius of curvature may also vary across the cross section of a rib. However, it should not be too small, preferably not smaller than one centimeter, to prevent the ribs 7 from being pressed into sensitive chilled goods.
Die Wandstärke der Bodenplatte 1 ist auf ihrer gesamten Ausdehnung konstant, d. h. auf der Unterseite der Bodenplatte 1 sind zu den Rippen 7 komplementäre Aussparungen 10 gebildet. Der Höhenunterschied zwischen den Kämmen der Rippen 7 und den Böden der Rillen 8 beträgt mehrere mm und ist größer als die Wandstärke der Bodenplatte 1.The wall thickness of the bottom plate 1 is constant over its entire extent, d. H. on the underside of the bottom plate 1 7 complementary recesses 10 are formed to the ribs. The height difference between the ridges of the ribs 7 and the bottoms of the grooves 8 is several mm and is greater than the wall thickness of the bottom plate. 1
Die Rippen 7 erstrecken sich nicht bis zu der vorderen Wand 2 und der hinteren Wand 4, stattdessen ist zwischen den Enden der Rippen 7 und den Wänden 2,4 ein quer zu den Rippen verlaufender Graben 1 1 gebildet. Dieser Graben 1 1 erleichtert das Reinigen der Bodenplatte 1 , da Rückstände aus den Rillen 8 schnell und einfach in einen der Gräben 11 hinein gewischt und von dort gemeinsam entfernt werden können. Um die Menge an Flüssigkeit zu vergrößern, die der Auszugkasten aufnehmen kann, bevor die Flüssigkeit den Kontakt mit Lagergut gerät, können die Gräben 1 1 tiefer als die Rillen 8 angeordnet sein. So kann Flüssigkeit aus den Rillen 8 in die Gräben 1 1 abfließen. Um die Verschiebbarkeit des Auszugkastens ist nicht zu beeinträchtigen, ist zweckmäßigerweise jeweils entlang der Seitenwände 3, 5 ein Graben 12 auf dem gleichen Niveau wie die Gräben 1 1 gebildet, wie in Fig. 3 dargestellt.The ribs 7 do not extend to the front wall 2 and the rear wall 4, but instead of a trench 1 1 running transversely to the ribs between the ends of the ribs 7 and the walls 2, 4. This trench 1 1 facilitates the cleaning of the bottom plate 1, as residues from the grooves 8 quickly and easily wiped into one of the trenches 11 and can be removed from there together. In order to increase the amount of liquid that can take up the drawer before the liquid comes into contact with stored material, the trenches 1 1 can be arranged deeper than the grooves 8. Thus, liquid can flow out of the grooves 8 into the trenches 1 1. In order not to impair the displaceability of the pull-out box, a trench 12 is expediently formed along the side walls 3, 5 at the same level as the trenches 11, as shown in FIG.
Die oben beschriebenen Ausgestaltungen können ein Wegrollen von Kühlgut nur quer zu den Rippen 7 verhindern, nicht aber in deren Längsrichtung. Und auch eine Sicherung in Längsrichtung zu erreichen, ist eine Modulation des Höhenprofils der Bodenplatte in zwei zueinander orthogonalen Richtungen erforderlich. Während das Höhenprofil h einer Bodenplatte mit in Tiefenrichtung verlaufenden Rippen beschrieben werden kann als h(x, y)=f(x), wobei x eine Koordinate in Breitenrichtung und y eine Koordinate in Tiefenrichtung der Bodenplatte bezeichnet und f eine periodische Funktion, z. B. eine Sinusfunktion, ist, wird in der Ausgestaltung der Fig. 4 ein Bodenprofil der Form h(x, y)=f(x)+f(y) verwendet. D. h. im Vergleich zur Ausgestaltung der Fig. 2 oder 3 ist auch die Höhe der Rippen 7 und Rillen 8 in deren Längsrichtung moduliert, so dass punktuelle Spitzen 13 und Senken 14 erhalten werden. Fig. 4 kann hier sowohl als ein Schnitt in Breitenrichtung des Auszugkastens, wie durch die Linien II, Il bezeichnet, aufgefasst werden, als auch als ein Schnitt in Tiefenrichtung, wie die durch die Linien IV, IV bezeichnet. Die Profile der hier mit 1 ' bezeichneten Bodenplatte in den beiden Schnittrichtungen unterscheiden sich nicht voneinander. Der Schnitt der Fig. 4 verläuft durch die lokalen Senken 14 und durch Sattelpunkte 15 zwischen jeweils zwei vor und hinter der Schnittebene liegenden Spitzen 13. Ein zur der Schnittebene der Fig. 4. paralleler Schnitt durch die Spitzen 13 würde einen Verlauf der Bodenplatte 1 ' ähnlich dem in Fig. 3 gezeigten ergeben, mit einem im Mittel höheren Bodenniveau als in Fig. 4.The embodiments described above can prevent rolling of refrigerated goods only transversely to the ribs 7, but not in the longitudinal direction. And also to achieve a backup in the longitudinal direction, a modulation of the height profile of the bottom plate in two mutually orthogonal directions is required. While the height profile h of a bottom plate having ridges extending in the depth direction can be described as h (x, y) = f (x), where x denotes a coordinate in the width direction and y denotes a coordinate in the depth direction of the bottom plate and f denotes a periodic function, e.g. As a sine function is, in the embodiment of Fig. 4 is a bottom profile of the form h (x, y) = f (x) + f (y) is used. Ie. Compared to the embodiment of Fig. 2 or 3, the height of the ribs 7 and grooves 8 is modulated in the longitudinal direction, so that punctiform tips 13 and depressions 14 are obtained. 4 can be understood here as both a section in the width direction of the pull-out box, as indicated by the lines II, II, and as a cut in the depth direction, as indicated by the lines IV, IV. The profiles of the here designated 1 'bottom plate in the two cutting directions are not different from each other. The section of FIG. 4 extends through the local depressions 14 and through saddle points 15 between two respective peaks 13 located in front of and behind the section plane. A section parallel to the sectional plane of FIG. 4 by the tips 13 would follow a course of the base plate 1 '. similar to that shown in FIG. 3, with a mean higher ground level than in FIG. 4.
Anstatt periodische Funktionen den zwei Raumrichtungen x, y additiv zu überlagern, kommt auch eine Multiplikation in Betracht: h(x, y)= f(x)*f(y). Ein Schnitt durch ein als ein solches Produkt periodischer Funktionen beschreibbares Profil einer Bodenplatte, mit 1 " bezeichnet, ist in Fig. 5 zu sehen; wiederum kann der Schnitt sowohl als ein Schnitt in der Ebenen der Linien II, Il als auch in der Ebene der Linien IV, IV von Fig. 1 aufgefasst werden. Im Falle eines Schnitts in Breitenrichtung (Ebene der Linien II, II; x = konstant) entspricht die gezeigte Schnittebene einem Wert der Tiefenkoordinate y, bei dem f(y) minimal und negativ ist; der Verlauf eines Schnitts entlang einer Ebene, in der f(y) maximal und positiv ist, ist anhand der mit 16 bezeichneten Kontur leicht vorstellbar. Anders als die Bodenplatte V der Fig. 4 weist die Bodenplatte 1 " Schnittebenen, z. B. entlang der Linie A, auf, in denen die Höhe nicht variiert, weil f(y)=O ist.Instead of superimposing periodic functions on the two spatial directions x, y, multiplication is also considered: h (x, y) = f (x) * f (y). A section through a profile of a base plate, described by 1 "as describable as such a product of periodic functions, can be seen in Fig. 5, again the section can be seen both as a section in the planes of lines II, II and in the plane of Figs Lines IV, IV of Fig. 1. In the case of a section in the width direction (plane of the lines II, II, x = constant) corresponds to the shown Sectional plane a value of the depth coordinate y, where f (y) is minimum and negative; the course of a cut along a plane in which f (y) is maximal and positive is easily conceivable on the basis of the contour designated 16. Unlike the bottom plate V of Fig. 4, the bottom plate 1 has sectional planes, for example along the line A, in which the height does not vary because f (y) = 0.
Fig. 6 zeigt eine Abwandlung der Fig. 1 , 2, bei der die Rippen 7 und Rillen 8 nicht in der Bodenplatte des Auszugkastens selbst, sondern in einer in den Kasten lose eingelegten Platte 17 gebildet sind, während die Bodenplatte 1"' selber eben ist. Eine solche Ausgestaltung hat den Vorteil, dass die Platte 17 leicht entnommen und gereinigt werden kann, so dass eine Reinigung des kompletten Auszugkasten seltener erforderlich ist. Die Einlegeplatte 17 kann die gesamte Bodenplatte 1"' des Auszugkastens abdecken. Alternativ können auch mehrere Platten 17 vorgesehen werden, die nebeneinander anzuordnen sind, um die Bodenplatte 1 "' komplett abzudecken. Dies hat insbesondere bei einem großformatigen Auszugkasten den Vorteil, dass die einzelnen Platten 17 mit Abmessungen gefertigt sein können, die eine Reinigung der Platten 17 in einer Spülmaschine gestatten.Fig. 6 shows a modification of Fig. 1, 2, wherein the ribs 7 and grooves 8 are not formed in the bottom plate of the pull-out box itself, but in a loosely inserted into the box plate 17, while the bottom plate 1 "'itself even Such an embodiment has the advantage that the plate 17 can be easily removed and cleaned, so that a cleaning of the complete drawer is required less frequently.The insert plate 17 can cover the entire bottom plate 1 "'of the pull-out box. Alternatively, it is also possible to provide a plurality of plates 17 which are to be arranged next to each other in order to completely cover the bottom plate 1 "." This has the advantage, in particular in the case of a large-sized pull-out box, that the individual plates 17 can be made with dimensions which allow the plates 17 to be cleaned in a dishwasher.
Die Platte 17 ist an ihrer Unterseite mit vereinzelten Noppen 18 versehen, die sich punktuell auf der Bodenplatte 1 "' abstützen. Indem so ein flächiger Kontakt zwischen Einlegeplatte 17 und Bodenplatte 1"' verhindert wird, ist gewährleistet, dass die Einlegeplatte 17 auch dann leicht entnommen werden kann, wenn Feuchtigkeit zwischen sie und die Bodenplatte 1 "' eingedrungen ist.The plate 17 is provided on its underside with isolated nubs 18, which are selectively supported on the bottom plate 1 "', thus preventing flat contact between the insert plate 17 and the bottom plate 1"', ensuring that the insert plate 17 is light even then can be removed when moisture has penetrated between them and the bottom plate 1 "'.
Selbstverständlich kann auch bei der Einlegeplatte 17 das Höhenprofil in Breiten- und Tiefenrichtung moduliert sein, wie mit Bezug auf die Figuren 4, 5 beschrieben. Dies ist in Fig. 7 in einem zu Fig. 4 analogen Schnitt veranschaulicht. An den lokalen Senken 14 sind hier jeweils Bohrungen 19 in der Einlegeplatte 17 gebildet, durch die Feuchtigkeit, die in eine der Senken 14 fließt, in einen Zwischenraum 20 zwischen der Einlegeplatte 17 und der Bodenplatte 1"' gelangen kann und so vom Kühlgut ferngehalten wird. Of course, also in the insert plate 17, the height profile can be modulated in the width and depth directions, as described with reference to Figures 4, 5. This is illustrated in FIG. 7 in a section analogous to FIG. 4. Holes 19 in the insert plate 17 are formed here at the local depressions 14, through which moisture which flows into one of the depressions 14 can enter an intermediate space 20 between the insert plate 17 and the bottom plate 1 "and thus be kept away from the refrigerated goods ,
