Definitions

  • the invention relates to a sales freezer with a goods compartment, which has on its top a cover which is formed by a roller blind, which is connected to a winding device attached to the sales freezer.
  • Such sales furniture are used as freezers or freezers, for example for the presentation of goods in supermarkets.
  • the merchandise area of freezer cabinets is open at the top in order to provide the customer with an overview of the stored range of goods and to enable them to take goods.
  • a cover device which contains a roll-up blind that can be developed.
  • the roller blind is usually extended outside of the sales hours to cover the goods area and to reduce the penetration of heat into the goods area.
  • the winding device of DE-A-34 05 825 is attached to an attachment which is arranged in the middle of the furniture above the goods area.
  • the otherwise advantageous central arrangement of the winding device is limited in its application to chests; a possible attachment to a long side of the chest would in turn only be possible with chests with a relatively small transverse expansion.
  • the object of the invention is therefore to develop a freezer of the type mentioned at the outset, which is not bound by these restrictions.
  • the roller blind cover should also be applicable to large width chests.
  • This object is achieved in that the goods space is divided into two sub-spaces by a central divider running parallel to the winding device and in that the winding device is arranged on the top of the central divider.
  • the roller blind can be arranged in the middle of the goods space, that is to say approximately along the longitudinal central axis of the chest, without an attachment or the like being necessary.
  • the winding device is arranged more densely than in the known solution above the upper edge of the goods space, so that the insulating effect when the blind is extended is significantly improved.
  • chests that are already equipped with a center divider for example for introducing cooling air into the center of the goods area, can be equipped with a night cover without additional devices.
  • the winding device is arranged essentially at the level of the upper edges of the outer walls which delimit the goods space. Losses in the covered state, which arise from the entry of warm air into the goods area, can thus be almost completely avoided.
  • the two winding devices are preferably equipped with drive means which can be actuated independently of one another. These can be crank mechanisms; however, electric motors switched independently of one another are preferably used.
  • the roller blind is held in the extended state by a linkage which consists of elements which are connected to one another via joints.
  • the linkage is preferably arranged above the roller blind, that is to say outside of the cold goods area.
  • the roller blind can be tensioned in the extended state by a spring element, which is preferably connected to the linkage.
  • the winding device is arranged in a housing which has openings for extending the roller blind, these openings being covered by a strip when the roller blind is retracted.
  • a heating device can be provided in the interior of the housing, which is preferably formed by heating wires which run over substantially the entire length of the housing approximately along the lower edges of the housing.
  • roller blind is designed to be heat-reflecting on its underside in the extended state.
  • Aluminum for example, can be vapor-deposited on the underside of the roller blind fabric oriented towards the cold room.
  • roller blind can be on its upper side when extended be designed to absorb heat.
  • the outward-facing top of the roller blind fabric can, for example, be colored dark.
  • the embodiment of a freezer according to the invention shown in the drawings has a goods room 8 which is divided by a center divider 1.
  • the middle divider 1 can contain an inlet air duct and outlet openings for cooling air.
  • the two shafts 3 are preferably driven by a motor. This means that night coverage can be carried out automatically.
  • roller blinds 4 and one of the two are shown in FIGS. 1 and 2 in a partially extended position. They run almost completely horizontally, directly at the upper edge of the goods room 8. This effectively prevents the undesired lateral penetration of ambient air in the covered state.
  • Two linkages 6 per roller blind 4 and an edge profile 9 serve to stabilize the roller blind 4 in the extended state, in particular against sagging into the goods space 8.
  • the rods 6 support the roller blind 4 from below. However, it is particularly favorable to place the rod or rods, deviating from the drawing, above the roller blind, that is, outside of the room to be cooled.
  • the underside of the roller blind fabric, which is oriented towards the cold room, is heat-reflecting, for example by vapor-deposited aluminum, while the upper side (to the outside) is heat-absorbing, for example by dark or black coloring.
  • the edge profile 9 in the retracted state serves as a cover strip for the openings 10 of the housing 2.
  • the linkage 6 and thus that Entire roller blind 4 are tensioned by spring elements 5, here realized by gas springs.
  • Heating wires 7 accommodated in the housing 2 prevent the extended blinds from fogging up.
