Description

Refrigerated goods container for a refrigeration device

The present invention relates to a refrigerated goods container, in particular a drawer, for a refrigerator, in particular for a household refrigerator. Refrigerated goods containers of refrigerators, in particular pull-out boxes, often have

considerable edge lengths, and their base area may correspond to the base of the storage space of the refrigerator or half thereof. At full load such a refrigerated goods thus considerable forces on the base and the

Side walls of the refrigerated goods container act. 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.

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 can be formed closed, so that a moister microclimate can be maintained in the interior of the refrigerated goods, as in particular in the storage room of the refrigerator, in which the

Refrigerated goods container is arranged.

The object is achieved by a refrigerated goods, 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 are formed adjacent to each other, the bottom plate in a cross-section extending along a trough in at least one, preferably in two directions is downhill. The wave trough thus forms a gutter for

Humidity. 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 two-way sloping wave trough whose longitudinally curved or longitudinally bent shape also causes a

Torsionsversteifung, which lacks the conventional refrigerated goods with corrugated bottom.

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.

A refrigerated goods container of high rigidity can also be obtained by placing in a refrigerated goods container with a bottom plate surrounded by walls in which

side by side extending wave crests and wave troughs are formed, in particular in a refrigerated goods of the type defined in the preceding paragraph, the

Height difference between wave crests and troughs is greater in those of two transverse to the wave crests and troughs oriented cutting planes, which is farther away from a median plane of the refrigerated goods. The stiffening effect of

Wave crests and troughs thereby increase 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.

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.

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.

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 wave troughs have a parabolic cross-section.

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. 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.

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:

1 is a perspective view of a halved refrigerated goods according to the

present invention;

2 shows a cross section of the refrigerated goods container. and

Fig. 3 is a longitudinal section through the refrigerated goods.

An inventive refrigerated goods container 1 in the form of an extension box is shown in Fig. 1 bisected in the longitudinal direction to show a cross section through a bottom plate 2 of the refrigerated goods 1. The cutting plane is also a

Symmetry plane 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 refrigerator, the door is facing, is facing away from the viewer in Fig. 1. 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

Wave troughs 9, each extending parallel to the front wall 3 and rear wall 4. However, it is also possible to form the bottom plate 2 such that the

Wave crests 8 and troughs 9 extend parallel to the side walls 9. 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 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 separated from the refrigerated goods and seeping into the troughs 9, run along the troughs 9 to the side walls 6 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.

2 shows a cross section through the halved refrigerated goods container 1, from the longitudinal center plane 12 of the refrigerated goods container 1 shown as a dotted line to one of the side walls 6. The sectional plane of Fig. 2 extends at the bottom of a wave trough 9, and from the sectional plane to both Side walls 6 sloping curvature of the soil course and the horizontal orientation of the wave crests 8 can be clearly seen. The wave trough 9 describes in the section of Fig. 2 of one of the side walls 6 to the opposite side wall 6 toward a cambered course, the maximum at the longitudinal center plane 12 is located. 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 one of the longitudinal center plane 12 to the side walls 6 out linearly sloping shape. 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 12 of the refrigerated goods container 1, which is also the sectional plane of FIG. 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 troughs 9 are parallel and the height difference along the troughs between hO and h1 variable, the ratio between the distance D and the height difference in the width direction of the refrigerated goods 1 varies by the value 3. As in the frontal view of FIG 3, the central region 7 is composed in longitudinal section of a plurality of respectively alternately curved parabolic arcs corresponding respectively to the wave crests 8 and wave troughs 9, the slope of which is always highest at intersections 11 to which a parabolic arc of a wave crest 8 accompanies a parabolic arc of a wave trough 9 abuts one another. The angle that the top of the bottom plate 2 to this

Points of intersection 1 1 forms with the vertical, varies from a ₀ = about 45 ° on the

Longitudinal plane 12 to oti = about 30 ° at the ends of the wave crests. 8

The radii of curvature of the troughs 9 can from the radii of curvature of the

Wave crests 8 may be chosen differently. In particular, the radii of curvature wave crests 8 are greater than the radii of curvature of the troughs 9 selected so that pressure points are avoided on refrigerated goods.
