Definitions

  • the invention relates to a sales counter or showcase for food according to the preamble of claim 1.
  • a sales counter of this type is known from DE-A-2 505 390.
  • a refrigeration unit with an integrated evaporator and a cross-flow fan are installed in the substructure below the goods showroom (display), which sucks heated air out of the display and guides it over the evaporator.
  • Part of the air cooled on the evaporator is led via a vertical cooling air duct on the back of the delivery into the top of three delivery compartments one above the other, from where the cooling air sinks into the delivery compartment underneath.
  • the lowest compartment designed as a reserve cooling compartment, is fed directly with the other part of the air cooled on the evaporator.
  • the overall efficiency of this forced air cooling is unsatisfactory.
  • a significant fan power must be installed to transport the cooling air.
  • the object of the invention is to improve the cooling efficiency in a sales counter or display case without increasing the structural outlay.
  • the invention is based on the idea of installing the evaporator below the (upper) ceiling plate of the display, ie at the highest point of the display. As the heated air rises to the ceiling panel within the delivery, it is cooled directly on the evaporator located there.
  • the refrigeration unit for supplying the evaporator with liquid refrigerant is located outside the display, for example in the base of the sales counter, or outside the sales counter.
  • the connecting lines between the refrigeration unit and the evaporator run in the area of the display in an optically invisible manner in support bars or the like. The same applies to one or more drain lines for removing condensate that collects in a collecting trough arranged below the evaporator.
  • the catch warning is preferably provided with a gradient in the transverse and longitudinal directions of the display, so that the lowest point of the catch trough lies at a longitudinal end of the display, where carrying bars of the sales counter are also located.
  • the customer does not consciously perceive the evaporator visually when his gaze is focused on the goods within the delivery.
  • the front window can be provided with an opaque screen, strip or the like. If necessary, price labels for the goods lying vertically underneath can be attached between the cover and the windscreen.
  • the evaporator preferably extends essentially over the entire length of the delivery, so that a constant cooling effect is ensured along the entire delivery.
  • the sales counter 1 shown in perspective in FIG. 1 has an upper structure 2 and a lower structure 3.
  • the superstructure 2 fulfills the two actual functions of the sales counter, namely the presentation of the goods to the customer with simultaneous hygienic protection and cooling of the presented goods.
  • an inclined, deeply drawn down front pane 4 (with end-sided side windows) is provided, which closes the display 1a of the sales counter 1 towards the customer.
  • the superstructure 2 carries a worktop 5 on an upwardly drawn console, as a result of which the sales staff standing behind the sales counter 1 can comfortably reach into the display 1 a which is open to the rear and thus freely accessible.
  • the top of the display 1a is covered by a ceiling plate 6, e.g. in the form of a number strip, the width of which is narrow compared to the worktop 5.
  • the ceiling plate 6 is supported at least in the region of the longitudinal ends by hollow support bars 8 (only one of which is shown in FIG. 1), which are anchored to the rear wall of the superstructure 2.
  • the carrying struts 8 can also run on the front of the sales counter 1 instead of on the back, which is, however, irrelevant to the invention.
  • the underside of the display 1a is formed by a floor pan 7, which forms a sealing closure with the lower edge of the front pane 4.
  • an evaporator 11 for cooling the delivery 1a is attached below the ceiling plate 6.
  • the refrigerant tubes of the evaporator 11 run in a meandering manner over the entire length of the ceiling plate 6, so that the delivery 1a is cooled uniformly in the longitudinal direction.
  • the heated air inside the delivery 1 a rises up to the ceiling plate 6, where it meets the evaporator 11, is cooled there and sinks down against the floor pan 7.
  • the refrigerant is supplied to the evaporator 11 from a refrigeration unit 9 via a refrigerant line 10a.
  • the refrigerant line 10a runs in the area of the display 1a at one longitudinal end of the counter 1 through the hollow support bar 8 and is therefore invisible from the outside.
  • the refrigerant is removed from the evaporator 11 via a refrigerant drain line 12a, which is guided at the same longitudinal end on which the refrigerant line 10a runs or at the other longitudinal end of the sales counter 1 through the hollow support bar 8 there and opens into the refrigeration unit 9.
  • the refrigeration unit 9 is located either in the substructure 3 of the sales counter 1 or outside the sales counter 1 and can optionally additionally supply refrigerant channels 7a via branch lines 10b and 12b, which are integrated within the floor pan 7. Alternatively, a separate cooling machine (not shown in the drawings) is provided for cooling the floor pan 7.
  • the drain line (s) 14 as can be seen from FIG. 2, open into a condensate collecting container 15 or into a drain connection for a sewage system.
  • FIG. 3 a construction of the sales counter 1 that is modified compared to FIG. 1 is provided.
  • the in the area of the two long sides Existing hollow spars 8 run in Fig. 3 in front of the windshield 4 and are supported with their lower ends on an arm 14 which is mounted on the base 2 on pivot bearings 14a.
  • the hood formed from the arms 14, the support bars 8, the front window 4 and the cover plate 6 surrounds the display 1a and can be pivoted out about the pivot bearing 14a with respect to the base plate 7, as a result of which the display 1a can be cleaned more easily.
  • the evaporator 11 attached below the ceiling plate 6 has refrigerant pipes running in the longitudinal direction of the delivery 1 a, which are connected at their ends to form a continuous strand.
  • the drip pan 13 is designed in one or two stages.
  • An illumination device 16 for example one or more fluorescent tubes, is accommodated to the side of the collecting trough 13 or immediately below it.
  • a narrow screen 17 can be provided behind the front screen 4 or as part of the front screen 4.
  • Price plates for the goods located vertically underneath can be attached between the panel 17 and the front screen 4 in a manner not shown.
  • the invention is not limited to sales counters, but can equally well be used in closed sales cabinets from which the customer can take the refrigerated goods on display.
