Closable container for receiving goods to be protected against temperature changes, particularly cooled goods

0001The invention relates to a sealable Container for receiving from temperature changes to be protected material, particularly refrigerated, with at least one closure element, the least a closed position in which becomes effective seal is assigned for the respective sealing gap.

0002Known closable containers of aforementioned genre are for. instance refrigeration units, their Closure elements as doors or drawers are formed. The container is usually equipped with a refrigerating machine so that the Temperature in the interior of the container to Cooling of the refrigerated goods are lowered accordingly can. To the thermal losses of container to minimize, the walls of container a thermal insulation in which a Heat conduction through the wall avoids. About that addition, the walls of each between Container or the closure element formed Sealing gap has a sealing assigned so that the Sealing gap in the closed position of the respective Closure member is sealed.

0003It is known that the respective in the range Seal gap-limiting walls of the container or the closure element preferably cold bridges formed with portions of these walls in the area can be a dew point, so that the Moisture contained in the air at this condense portions of the walls in the sealing gap can. Consequently, if the known Containers to an unwanted condensation and possibly even to adverse icing.

0004The invention is based on the object, a Container of the aforementioned type provide that with regard to its Insulation, in particular in terms of Condensation critical area of ​​each Closure element associated sealing gap is improved.

0005This object is inventively achieved in that each seal is an extruded profile, which, following the course of the respective sealing gap, is mounted such that the seal at least partly with predetermined Profile areas located in the sealing gap, and that at least the predetermined profile of the area Seal is elastically deformable, such that resulting from clamping forces Contact pressure a for positively completing the Seal gap leading flattening of the seal causes the mounting of the seal in such a way is made that formed by the flattening Schmiegeflächen the seal to a respective sealing gap-limiting walls of Container or the closure element so bear that in the field of Dew point lying sections of the walls, defining a sealing gap, are covered.

0006The dimensions and shape of the profile of Seal, in particular its effect on the sealing Profile Areas primarily involved, are so chosen so that the seal, or its profile areas the predetermined width of the predetermined Seal gap fill at least. In Closed position presses the sealing gap limiting walls of the container or the Closure element therefore the seal, at least However their elastically deformable profile area together such that the seal at this Walls optimally invests in the area of Dew point lying sections of the respective sealing gap-limiting walls be fully covered. The covered Portions of the walls thus have no contact with Air, so that condensation of air in the Moisture contained advantageously in these critical areas is prevented. The unwanted condensation with Icing hazard thus does not occur. This is in particular for refrigeration units with metallic Relevant surfaces that have a high having thermal conductivity, so that the dew point can be outside of the refrigerator compartment. Such Refrigeration equipment with metallic surfaces, in particular of chromium-nickel steel, are before mainly used for industrial purposes.

0007In the container according to the invention is provided, that the predetermined profile areas each Seal from the inner portion of the container into extend into the sealing gap. Thus, in advantageously ensures that even the with regard to the formation of condensation especially vulnerable portions of the walls, the one limit sealing gap, of the predetermined covered profile areas of the seal.

0008Each seal can be applied to the formation of the Sealing gap involved portions of the walls of each be arranged closure element. The strand-like seal can, for example, along of the respective sealing gap-limiting walls run of the closure element, wherein the Closure element comprises a door, a drawer or like can be. The seal is the Closure element for example glued or like firmly connected. It is also possible, that the seal releasably attached to the walls of the Closure element, for example by Screw, is attached. Of course , the walls of the closure element also in the matched predetermined profile areas of the seal have shapes, in the as extruded profile trained seal inserted positively, z. B. be inserted.

0009It is also conceivable that each seal to Portions of the respective sealing gap limiting walls of the container is maintained. Thus, the seal is stationary. Of course, the gasket may in turn detachable or fixed to the facing the sealing gap Portions of the inner walls of the container be connected.

0010The lying in the range a dewpoint Portions of the walls of the container or of the Closure element are in a particularly advantageous development with breakthroughs provided that each of the cross-sectional area openwork wall decrease. By Reduction in cross-sectional area of ​​each of the limitation of the sealing gap involved walls the container, or of any Closure element, the thermal resistance is increases the perforated wall so that the Heat conduction, particularly in terms of condensation critical sections of Walls is reduced. At the same time the Breakthroughs advantageously for attachment be used by extensions and additional equipment. For example, hinge fittings, hinges or the like Anlenkorgane for doors or Guides for drawers with appropriate, in predetermined breakthroughs engaging Fasteners are mounted. The Breakthroughs can also for attaching Supports for the interior of the container dividing shelves are used. Around to obtain a continuous surface, which also is easy to clean, the breakthroughs can a poor heat-conducting material such as Silicone, be closed.

0011According to a development of the invention are the Breakthroughs circular, but other such. B. oval, square or the like forms of Breakthroughs are possible. The shape of the openings can the particular desired use, eg. For example, for attachment of the fastener elements or his shelves adapted. Several breakthroughs can be arranged in series, for. example, wherein preferably a plurality of rows of apertures are arranged side by side. The openings each of adjacent rows with Particularly advantageously offset from one another, whereby the heat conduction in the wall effective cross-section is minimized even further.

0012The thermal insulating properties of a usually consists of thermally insulating material existing seal is advantageously improved in that the extruded profile as trained seal at least one cavity having. The cavity has a thermally insulating. Furthermore, cavities and to accommodate Stiffeners are used.

0013A preferred embodiment of the invention before, that the seal formed tubularly is. Preferably as material for the Sealing a gummy plastic such. B. Foam rubber is used. Foam rubber has the advantage that due to its cell-like structure a has low thermal conductivity and as an insulator acts. In addition, foam rubber is advantageous formed purely so that one consisting thereof Seal because of the special elastic Property of this material optimally to the sealed walls or surfaces snugly.

0014After development, the tubular Sealing at least one shape retaining member on. The shape retaining member may in the tubular seal member captured in the design of a profile, it being the Profile shape depending on the design of the sealed Seal gap is arbitrary. such Seal has the advantage that the shape specified by designed as a shape retaining member profile, by the contact pressure in the closed position of the Closure element caused elastic deformation the seal, in particular their predetermined Profile areas, such pretending that they at the the respective sealing gap-limiting walls of the Container or the closure element optimal snugly. Further, the Shape retaining elements are also used to a secure attachment of the gasket to the Closure member or container, for. Example by Screwing of the shape retaining member formed profile at a a sealing gap defining wall to ensure.

0015In a particularly preferred embodiment of the Invention, the closure element in size so dimensioned that it at the inside dimension of the Container is adapted and in the closed position to an inside of the container adjacent. If that Closure element is designed as a door, Thus, the door does not hit the wall of the On container, but inside is inserted. The seal is then conveniently fixed frontside disposed of the closure element, so that the Seal between the inner sides of the container and the end faces of the closure element to the Used. To a cross sliding of to ensure the closure member into the container the seal is preferably designed so that the Seal at the surface low having friction coefficient. This can for example, by a hard but at the same time elastic fabric layer can be achieved, the is made for example of polyester and rear with a flexible material is coated. Here, for example rubber, Foam rubber or PVC are used.

0016To the sealing function which in the erfindinngsgemäßen container used to seal improve, it is provided that any predetermined Profile portion of the seal of thermally insulating and soft elastic material with a hardness <70 Shore is. such a Material is serving as contact surfaces Profile areas a high elastic Deformability, bringing the profile areas optimally to any given form of can create a seal gap-limiting walls. Of course, the entire seal made of such a material.

0017In the container according to the invention, it may happen that of rubber-like material existing seal with their predetermined Profile areas such at the sealing gap walls delimiting liable that in the closed position inadvertent opening of the closure element is advantageously prevented. However, in order conformal while adhering seal of the in the formation of the sealing gap to be sealed involved walls in order to open the container about as simple to solve again without expend large opening forces is provided, that the predetermined profile areas of the seal at least partially a surface structure roughening have. Thus, only a pointwise contact between the predetermined Profile areas of the seal and the walls given, whereby the adhesion between the seal and Walls is reduced and the opening of the Container without too much effort possible is. Further, due to the reduced Friction between the wall and seal wear the seal can be advantageously reduced.

0018A profiled surface structure can be formed such that the surface of the seal a arranged on the sealing fabric layer. Preferably, the predetermined profile areas the gasket having a fabric layer provided. Of course, the entire Surface of the seal such a fabric layer exhibit or the entire seal from z. B. rubberized fabric.

0019In containers formed with the drawers Closure elements each having a said closure have the container serving faceplate, is adjacent to the and through the walls of container limited the front panels of the drawers Sealing gap an additional, respectively between Walls of adjacent drawers existing Seal gap seal. This aspect of the invention can as an independent inventive idea to be viewed as. The seal for sealing the Seal gap is according to a development characterized in that a front end of the seal a smaller width than the sealing gap between having the front panels of drawers, and that a rear portion of the seal behind the Front panels of the drawers of drawers is arranged, with the rear region of the Sealing a greater width than the sealing gap comprises between the front panels.

0020The seal preferably extends between lateral inner walls of the container, wherein the Gasket with their free ends, z. B. by correspondingly shaped end brackets, each is held stationary on the inner wall of the container is. The seal is arranged so that in the closed position of the drawer at least the predetermined profile areas of the seal from the Interior of the container in the sealing gap in extend. Preferably, the seal a wedge-shaped cross-sectional shape in which the predetermined profile areas through the wedge flanks are formed of the wedge-shaped seal. The V-flanks of the elastically deformable seal nestle such to the sealing gap walls delimiting the front panels of the drawers on that turn a large area of ​​plant Seal is given that to cover the lying area a dewpoint Portions of the walls of the front panels of the Drawers leads. Course also other cross-sectional shapes of the seal, such Example circular, oval, square or like forms possible. A wedge-shaped However, cross-sectional shape of the seal has the Advantage that the seal in the gap between the Front panels of drawers, even with very small gap widths is always threaded safe and thus an optimum sealing function at an inserted drawer or closed met container.

0021A development of the invention provides that the Container as refrigeration units with at least two Drawers is formed, each one of the Closure of the cabinet serving faceplate have, and the front plates, a front forming thermal insulation of the cabinet, which in facing areas of drawers at least one fixedly arranged sealing is provided and the front panels of the Drawers by a sealing gap with a certain width spaced apart arranged are, each seal substantially in the Seal gap between the front panels is arranged and at least a portion of each seal in essentially the width of the sealing gap between having the front panels.

0022The seal may be a between lateral Inner walls of the container extending be hollow profile, wherein the seal with their free ends, for example by means of correspondingly formed end brackets, each of the Inner wall of the container is held stationary. The form of a hollow profile seal can for Example designed as a shape retaining member shaped profile, which, for example, an L- or T-profile shape. is with the shape retaining member In addition to the default form a stiffening of the achieved seal, so that a bending or Sagging especially for very long Sealing gaps that need to seal it, avoided becomes.

0023With the pre-sighted seal in which Refrigeration units, the sealing gap between the front panels the drawers securely sealed. Advantageously Way is the usable drawer height or available refrigerator of the cabinet is greater than previously known refrigeration units, since the width of the Seal only slightly larger than the width of the Seal gap between the drawers and hence the available drawer height not by the Seal is limited. In the hitherto known is refrigerated display the drawer, or the Refrigerator by a for affixing the seal significantly limits required cross rail because the width of the cross rail substantially greater than is the width of the sealing gap.

0024It makes sense that a forward end of the Sealing a smaller width than the sealing gap comprises between the front panels of the drawers, and that a rear portion of the seal behind the front panels disposed of drawers, wherein the rear region of the seal a greater Width than the sealing gap between the front panels having. With the seal is ensured that the sealing gap is completely sealed and the critical in terms of condensation Portions of the sealing gap-limiting walls the front panels of drawers covered. Preferably, the cross-sectional shape of the seal wedge-shaped, wherein the predetermined Profile areas formed by the faces of the wedge will. A wedge-shaped cross-sectional shape having sealing over other possible cross-sectional shapes the advantage that even at very low latitudes of the sealing gap the seal securely in the sealing gap between the inserted drawers can be threaded.

0025It is also possible that in the cooling furniture non-stationary seal is used. The Seal can, for example, on the front panels of the be arranged drawers, wherein the seal for Example is designed as a brush. The one Seal gap-limiting walls of the front panels of the Drawers can each one as a brush have seal formed so that the Seal gap when closed and inserted Drawers is sealed by the brush.
