CROSS-REFERENCE TO RELATED APPLICATION  
       [0001]     This application is a continuation, under 35 U.S.C. § 120, of copending international application No. PCT/EP03/01086, filed Feb. 4, 2003, which designated the United States; this application also claims the priority, under 35 U.S.C. § 119, of German patent application No. 102 07 990.0, filed Feb. 25, 2002; the prior applications are herewith incorporated by reference in their entirety.  
       BACKGROUND OF THE INVENTION  
     FIELD OF THE INVENTION  
       [0002]     The present invention relates to a refrigerator having a heat-insulating housing and at least one housing door for closing a storage space formed in the interior of the housing. The door is translucent at least over part of its surface area.  
         [0003]     Such refrigerators are used, in particular, in self-service grocery stores, where they are utilized for storing chilled food and allow customers to view the goods contained within, without the door of the refrigerator having to be opened for this purpose and undesired heat penetrating into the storage space.  
         [0004]     These appliances are configured as standing appliances, and their outer configuration is generally unremarkable and not particularly variable. As a result, they do not lend themselves well to being used in surroundings in which importance is placed on a pleasing appearance, for example in those areas of catering establishments which are accessible to the guests.  
       SUMMARY OF THE INVENTION  
       [0005]     It is accordingly an object of the invention to provide a built-in refrigerator with a translucent door which overcomes the above-mentioned disadvantages of the prior art devices of this general type, which makes it possible for goods which need cooled or temperature-controlled storage to be displayed in an esthetically pleasing form which can easily be adapted to the configuration and decor of a room in which the appliance is to be set up.  
         [0006]     With the foregoing and other objects in view there is provided, in accordance with the invention, a refrigerator. The refrigerator contains a built-in appliance which has a heat-insulating housing defining an interior with a storage space and at least one housing door for closing the storage space, formed in the interior of the housing. The housing door has a translucent part being translucent and extending over at least part of a surface area of the housing door.  
         [0007]     The object is achieved in that the refrigerator is configured as a built-in appliance.  
         [0008]     Conventional built-in refrigerators generally have a door with a front side that is not particularly esthetically pleasing, is made of an inexpensive material and is provided in order to be concealed behind a unit door rather than to be viewed directly by a user. The unit door and refrigerator door here are, for example, each suspended on a dedicated hinge and can be displaced in relation to one another on rails when opened.  
         [0009]     Turning away from the opinion, which has prevailed among experts up until now, that the doors of built-in appliances have to be adapted, in terms of appearance and/or design, to adjacent facing arrangements of a row of kitchen units, e.g. by unit facing configurations, a built-in refrigerator with a unique door of translucent construction is now proposed. The door of the built-in appliance thus stands out, in a technically enriching manner, from the adjacent facing configurations of a row of kitchen units.  
         [0010]     Such a unit door is dispensed with in the case of a preferred configuration of the refrigerator according to the invention.  
         [0011]     Instead, the housing door of the refrigerator itself may be produced from high-grade, esthetically pleasing materials.  
         [0012]     If, in the case of another configuration of the refrigerator according to the invention, a unit door is indeed provided, then, in particular if it is cut away in a region corresponding to the translucent surface area of the housing door, it may be more lightweight than a conventional unit door for a built-in refrigerator, with the result that it may be expedient to install the unit door in a non-displaceable manner in front of the housing door.  
         [0013]     The translucent part of the housing-door surface area is preferably transparent, in order for it to be possible to see all the details of articles stored behind it. It is also conceivable, however, to provide the housing-door surface area with a more or less intense degree of opaqueness, with the result that, although it is possible to see from the outside that there is an article present in the storage space, this article cannot be seen specifically.  
         [0014]     The translucent part of the housing door is expediently formed by an insulating glass panel, i.e. an arrangement of two or more glass panels that are separated in each case by insulating gas layers. The glass of the panels may be, in particular, mineral glass or a translucent plastic.  
         [0015]     The refrigerator according to the invention is preferably configured as a storage cabinet for bottles, in particular for wine bottles.  
         [0016]     Other features which are considered as characteristic for the invention are set forth in the appended claims.  
         [0017]     Although the invention is illustrated and described herein as embodied in a built-in refrigerator with a translucent door, it is nevertheless not intended to be limited to the details shown, since various modifications and structural changes may be made therein without departing from the spirit of the invention and within the scope and range of equivalents of the claims.  
         [0018]     The construction and method of operation of the invention, however, together with additional objects and advantages thereof will be best understood from the following description of specific embodiments when read in connection with the accompanying drawings. 
     
    
     BRIEF DESCRIPTION OF THE DRAWINGS  
       [0019]      FIG. 1  is a diagrammatic, perspective view of a refrigerator according to the invention; and  
         [0020]      FIGS. 2 and 3  are diagrammatic, sectional partial sectional views through an appliance door according to two different configurations of the invention. 
     
    
     DESCRIPTION OF THE PREFERRED EMBODIMENTS  
       [0021]     Referring now to the figures of the drawing in detail and first, particularly, to  FIG. 1  thereof, there is shown a refrigerator that has a housing which is constructed in a manner known per se from an inner container  1 , which is thermoformed from plastic and bounds the storage compartment in the interior of the appliance, and an outer wall  2 , which is joined together, for example, from metal sheets or may likewise be thermoformed from a plastic panel and, together with the inner container  1 , bounds an interspace with thermally insulating foam filling. Cross pieces  3  that are integrally formed on the sides of the inner container  1  bear shelves  4 ,  5 . The shelves  4 ,  5  are each constructed from a quadrilateral frame  6  which is made of die cast aluminum and on which are fitted a plurality of cylinder-segment-type trays  7  which extend in the depth wise direction of the inner container  1 . The trays  7  are each fastened on a front and a rear strut  8 ,  9 , respectively, of the frame  6  and are not connected to one another. The trays  7  are formed of a frosted, translucent mineral glass or plastic.  
         [0022]     A compressor of the refrigerating machine of the refrigerator is accommodated, in a manner known per se, behind a hollow  10  of the inner container  1 , the hollow  10  reaching into the storage compartment. It is not possible to install a rectangular shelf level with the hollow  10 ; in order to optimize the use of the space available here, a shelf  11  with a continuous panel is fastened on the frame  6  of the shelf  5  in a manner in which it is suspended via rods  12 . The shelf  11  and a floor surface of the inner container  1  located therebeneath can be utilized, in the region in front of the hollow  10 , for example for storing smaller bottles than those of dimensions appropriate for the trays  7 .  
         [0023]     The above-described storage compartment is visible through a closed housing door  13 . The housing door  13  is formed by an insulating glass panel  14  that fills a large part of the surface area of the housing door  13  and is surrounded in a frame that is made up of extruded aluminum profiles.  
         [0024]     Examples of a possible cross-sectional structure of the housing door  13  are shown in  FIGS. 2 and 3 , which each show a partial section through the housing door  13  level with the door handle  15 .  
         [0025]     In the case of the configuration of  FIG. 2 , the insulating glass panel  14  extends over the entire surface of the housing door  13  and a magnetic seal  16  for sealing a gap between the inner container  1  and housing door  13  is fastened on an inner panel  17  of the two panels  17 ,  18  which form the insulating glass panel  14 . Fastened on an outer panel  18 , in the peripheral region of the latter, is an aluminum profile  19  which has a C-shaped cross section, bears the door handle  15 , e.g. by screw connection, and can have its hollow interior  20  filled with insulating foam material. An outer covering of the housing door  13  is formed by a second aluminum profile  21  of C-shaped cross section, of which one of the two parallel legs butts against the outside of the profile  19  and the other butts against the inner panel  17 .  
         [0026]     In the case of the housing door according to  FIG. 3 , the two aluminum profiles  19 ,  21  are identical to those of  FIG. 2  and thus need not be described again. The insulating glass panel  14  is smaller than that of  FIG. 2 ; rather than reaching the outer profile, it terminates at a small distance from an inner leg  22  of the profile  19 . The inner panel  17  butts against a tongue  23  of a plastic profile  24 , which also fills part of an interior  20  of the aluminum profile  19  and is fixed to the profile  19 . It is also possible for the plastic profile  24  to be provided with insulating-foam-filled cavities, which are not illustrated in the cross section.  
         [0027]     In the case of a modification of the cross section of  FIG. 2  which has not been depicted, the aluminum profile  19  is dispensed with, and the outer aluminum profile  21  is dimensioned such that its legs each butt against the outside of the panels  17  and  18 . In this case, the door handle cannot be screw-connected; adhesive bonding to the outer panel  18 , however, is readily possible.  
         [0028]     It goes without saying that, in particular if the insulating glass panel  14  extends over the entire surface area of the housing door  13 , the two profiles  19 ,  21  can also easily be replaced by wooden profiles which have their outer configuration adapted, in the manner which is customary for built-in appliances, to the configuration of the built-in appliance of adjacent unit facing arrangements. Since these profiles only cover over a peripheral region of the insulating glass panel  14 , they are considerably more lightweight than a continuous unit-door leaf of the same size. For this reason, and also because the inside of the housing door  13  is not fitted, according to the invention, with article supports, the loading of which could increase the weight of the door, these wooden profiles can easily be born by the door-suspension device of the refrigerator and thus do not require any dedicated suspension device. It is thus possible for the wooden profiles to form a frame-like unit door.
