Definitions

  • the invention relates to a refrigeration device with an aggregate space around at least one of them heat-insulated storage space serving to store stored goods, which is surrounded by a heat-insulating housing and which is cooled by an evaporator lying in a refrigeration circuit with a compressor.
  • the cooling of the storage tanks with the cold accumulators is pretty Labor-intensive, since on the one hand they have to be pre-cooled in a refrigeration device and on the other hand they have to be arranged in heat-conducting contact around the container containing the drink for optimal cooling of this drink.
  • refrigerators used for cooling beverages stored in barrel-like containers which are constructed in the manner of a conventional household refrigerator and which have an opening in their door for the introduction of a dispensing device.
  • the invention has for its object to provide a refrigerator according to the preamble of claim 1, in which the disadvantages of the prior art are avoided and in which the loading of its storage space is significantly improved.
  • heat-insulating housing is detachably assembled from preformed housing modules which have at least approximately their final geometry.
  • a housing structure is provided by the solution according to the invention, and housing sections by its modular construction are produced, which are easy to handle and which, in contrast to the heat-insulating housings according to the prior art, do not require any complicated and therefore costly supporting tools for their production. Furthermore, by removing a housing module, the modular structure allows the storage space to be easily loaded with storage goods that are difficult to handle because of their weight and / or their shape, for example in the form of a beverage keg. In addition, an assembly-friendly housing with reduced assembly costs is achieved due to the modular structure.
  • the heat-insulating housing essentially comprises two housing modules, one of which forms the housing base and the other housing module has the jacket walls and the ceiling of the housing.
  • Such a subdivision of the heat-insulating housing minimizes the thermal bridges caused by the connection points between the individual modules and also makes access to the storage space considerably easier due to the integral construction of the housing module comprising the jacket walls and the ceiling of the housing.
  • the housing module comprising the casing walls and the ceiling of the housing, if it is provided according to a further preferred embodiment of the object of the invention that the housing module comprising the casing walls and the ceiling is essentially formed from heat insulation material and is removably arranged on the housing.
  • the housing module comprising the jacket walls and the ceiling, with its jacket walls, engages over the jacket surfaces of the housing base and is supported on the housing base.
  • the housing module is easily and precisely assigned in terms of its vertical position as well as with respect to the storage space.
  • the cold drain at the connection point between the housing base and the housing module comprising the jacket walls and the ceiling is clearly restricted.
  • the housing module having the jacket walls and the ceiling is provided on its ceiling with an opening which can be covered by a heat-insulated and detachably arranged cover cap.
  • the additional access opening to the storage space creates the possibility, for example, of dispensing a dispensing device arranged on a barrel-like beverage container from the storage space with a relatively low loss of cold.
  • the housing module comprising the jacket walls and the ceiling of the housing is, if according to a next preferred embodiment of the object According to the invention, it is provided that the housing module comprising the jacket walls and the ceiling of the housing is designed as a molded body formed from heat insulation material and provided on the jacket side with a film coating.
  • such a solution has the advantage that the film coating lends the housing module a decorative character, while at the same time producing a relatively wear-resistant and easy-to-clean surface.
  • the housing base is formed from a hollow body filled with heat insulation material, the body walls of which are produced from poorly heat-conducting material.
  • Poorly heat-conducting material is to be understood here to mean various types of thermoplastic, which are formed in the form of sheet material in a deep-drawing process to form a hollow body, the cavity of which is filled with heat insulation material introduced into liquid starting components, as a result of which, due to the wetting effect of the heat insulation material, a particularly dimensionally stable composite component for the Case bottom results.
  • the hollow space of the hollow body can also be filled with a molded body formed from heat insulation material, which results in the possibility of using the molded body as a base for the barrel-like beverage container when the refrigeration device is not in use.
  • the evaporator is designed as a flat evaporator and is detachably fixed to one of its narrow sides on the housing base.
  • the housing module comprising the ceiling and the casing walls can be removed from the housing base in a particularly simple manner without additional dismantling work.
  • a holding part shaped according to its contour which is arranged at a distance from the evaporator, is used to fix the evaporator on the housing base.
  • Such a construction creates a holder for the evaporator, which can also withstand shock loads e.g. withstands heavy goods in the storage room.
  • the holding part is designed as a bent sheet metal part and that the distance between this and the evaporator is filled with heat insulation material.
  • a solution of this type produces both a particularly inexpensive holding part, which is nevertheless provided with sufficient dimensional stability, and also a targeted one The evaporator gives off cold.
  • the holding part with its end facing the housing bottom is arranged in a form-fitting manner in a collecting channel provided on the housing bottom for melt water, into which the melt water formed when the evaporator is defrosted can flow and which essentially has the contour of the evaporator.
  • the evaporator is designed as a U-profile, between its legs arranged essentially vertically to the housing base the goods to be cooled can be brought in.
  • a machine room for the refrigeration units is produced in a particularly simple and inexpensive manner if, according to a further preferred embodiment of the object of the invention, it is provided that one for receiving is located below the storage room the refrigerating machine room is provided, which is arranged within a support base provided with an access opening and serving as a support for the heat-insulating housing.
  • the desired temperature can be applied particularly evenly over a longer period of time to the beverages stored in barrel-like containers if, according to a preferred embodiment of the object of the invention, it is provided that the refrigerator is used as a refrigerator for cooling beverages stored in barrels according to one of Claims 1 to 13 is formed.
  • Such a refrigerator also allows the beverage kegs to be introduced into the refrigerator with relatively little physical effort.
  • a cooling device 10 which is suitable for cooling beverages stored in barrels, such as beer barrels, and which is equipped with a heat-insulating housing 11.
  • This is essentially composed of two housing modules, of which a first housing module 12 comprises the top wall 13 with an opening 13.1 arranged therein and the jacket wall 14 of the heat-insulating housing 11.
  • the opening 13.1 can be covered with a heat-insulating cover cap 13.2 shaped in accordance with the opening contour and is used to attach a tap device (not shown) to a beverage keg (also not shown) in the form of a party beer keg, which is covered by the housing module 12.
  • the housing module 12 is designed as a shaped body that already has its final geometry, which is formed without cutting from heat insulation material, such as foamed polystyrene with a density of 80 to 100 kg / m 3 , and which is coated on its outer surface with a plastic film, not shown here. In addition to decorative purposes, this serves above all to increase the abrasion resistance and to improve the dimensional stability of the molded body.
  • the housing module 12 is circumferential at the free end of its jacket wall, on its inner jacket surface provided recess 15, the boundary surfaces are arranged perpendicular to each other, the shorter cross-sectional boundary surface serves as a support surface 16, while the longer of the boundary surfaces is designed as a sealing surface 17.
  • this is filled with heat insulation material 20 which is introduced into the cavity in liquid starting components and which connects to the walls of the carbon body 19, so that after the heat insulation material 20 has hardened, the housing base 18 has a very dimensionally stable structure.
  • the housing base 18 is provided on its top side facing the ceiling wall 13 with a channel-like depression arranged on three sides of its edge, forming a coherent watercourse and serving as a collecting channel 21, which is formed on the edge of the housing base 18 by non-cutting shaping of the plastic board on the top of the housing base 18 is molded in and which has at its lowest point a water outlet, not shown, via which the melt water is fed to an evaporation tray, not shown, arranged directly above a condenser, not shown.
  • the housing base 18, together with the housing module 12, encloses in a heat-insulating manner a cooling space 22 which serves as a storage space and which is cooled by a flat evaporator 23 with a U-shaped cross section.
  • This is manufactured, for example, according to the roll bonding process and is arranged on a narrow side of the housing base 18 along the collecting trough 21 that defines the contour of its cross section.
  • the height of the evaporator 23 is dimensioned so that the handles of the beverage barrel, not shown, are arranged above the upper edge of the two legs of the U-profile when the beverage barrel is inserted into the cooling space 22, which greatly facilitates the introduction of the beverage barrel into the cooling space 22 after the housing module 12 has been removed from the housing base 18.
  • a fastening element 24 designed to match the contour of the evaporator 23 is used to fasten the evaporator 23, which is arranged at a distance from the evaporator 23 and which is fixed to the housing base 18 with one of its end faces in the collecting trough 21 which additionally serves to reinforce the floor.
  • the holding element 24 is produced by angling a sheet metal plate, and has at its free edges a fold 25 which overlaps the evaporator plate 23 at its free edges, the tabs on its inside facing the circuit board body of the holding element 24, a stop surface for the plate-like evaporator 23 form.
  • a machine room 28 which is used to hold the refrigeration units, such as compressors, condensers and the like, is arranged within a support base 27 which supports the heat-insulating housing 11 and which is heat-insulated from the cooling space 22 by the housing base 18, the housing base being fixed is connected to the support base 27.
