Definitions

  • the invention relates to a method according to Preamble of claim 1 and a refrigerated counter according to Preamble of claim 8.
  • refrigerated counters are known, at which a so-called “silent” who is as motionless as possible Cold air lake is generated in the trough-shaped cooling counter, the bottom of which forms the display surface.
  • Figure 1 shows one such refrigerated counter according to the prior art, in which a Cooling element generates the stationary cold air lake, the Upper limit is indicated with a broken line.
  • the problem with this type of refrigerated counter is relative shallow depth of the cold air lake, corresponding to the permissible amount of goods displayed on the display area, in particular meat products, cheese, confectionery etc. limited.
  • Another type of refrigerated counter at which a cooling airflow flowing over the display surface is to be generated is e.g. from EP-A-571 331, DE-A-32 03 301 or CH-A-648 468 known.
  • air delivery means are provided on the delivery level, which to keep air circulation going, one Airflow from the front (customer side) of the counter to the cooling element located at the rear of the counter should effect.
  • the cooling element itself is arranged that an input channel forms above it, and the cooled air leaves the element down into the air flow means under the display surface.
  • the cited prior art documents show Passive facilities that do not use an external driven element, e.g. of a fan that Cause air circulation.
  • the disadvantage of having refrigerated counters the circulation solution is a much larger one Tendency to dry out the displayed goods as well as in the increased construction work for the air flow in the refrigerated counter below the display area.
  • the invention is based on the object Process or a refrigerated counter of the type mentioned to create, so with formation of a still cold air lake, where a higher lying cold air lake than to is achievable.
  • FIG. 1 shows a schematic vertical sectional view a refrigerated counter 1 according to the prior art.
  • the refrigerated counter has a trough-shaped area on, by side parts 2, one only partially shown glass hood 3, a bottom 4, a rear wall 5 and an upper end 7 is limited.
  • the front one Side of the refrigerated counter is at the slant Disc of the hood 3 and is e.g. provided by the customer provided with a pocket pad 17.
  • the opposite Side of the refrigerated counter is the rear side and forms part of it the top of the finish 7 a work surface for the sales staff.
  • the refrigerated counter shown generates a so-called still cold air lake 16, the upper limit is indicated with a dashed line.
  • a cooling element 9 which in the example shown as a rectangular, upright Cooling element arranged on the rear wall 5 of the refrigerated counter is and from the bottom 4 to the bottom 8 of the top end 7 extends.
  • the cooling can by a cooling plate 10 are supported, which together with the bottom 4 the display area for the in the refrigerated counter preserved goods.
  • the cooling surface 10 contains known way cooling coils in which a cooling medium circulates.
  • the cooling element 9 is conventional Way e.g. with a large number of metal plates, which form air passages between them, which plates by means of lines in which a cooling medium circulated, cooled.
  • the trough-shaped area of the Refrigerated counter 1 rests on a base frame 6, which e.g.
  • FIG. 2 shows an embodiment of a Refrigerated counter according to the invention.
  • the cooling element 19 which in construction a known cooling element any Construction that allows the air to pass through, e.g. can also be designed in panel construction, arranged so that the heated air to be cooled comes from above enters the cooling element 19 through a relative narrow channel 12, in which there is a higher speed of air than when arranging according to the state of the art according to FIG. 1 is.
  • the air passes through the front slit-shaped opening of the room 12 in this and thus from above in the Cooling element.
  • Figure 3 shows the rear area of the refrigerated counter 1 of Figure 2 in a larger representation.
  • a preferred element 14 is provided, which on the one hand in a known manner a privacy screen from the Forms customer side for the cooling element 19.
  • element 14 forms an air duct which causes that the air to be cooled is essentially only on the bottom of the cooling element 19 in the space 13 in Flows towards the floor and not already leaves the cooling element on the side.
  • the element has 14 passages which allow access allow the heated air in the channel 12, and thus favor entry into the cooling element from above, as shown by the corresponding arrow.
  • the Element 14 can, as shown, consist of two interconnected Consist of parts which e.g. made of sheet metal are.
  • the element 14 preferably further has lower angled end 15, which e.g. in the direction angled towards the rear wall 5 of the refrigerated counter is. This can also influence the air flow be that the cold air lake 16 is disturbed as little as possible is and through which the cooling element 19 down to Air 4 leaving bottom 4 essentially only one Raising the cold air lake is achieved.
  • FIG. 3 further dimension lines with corresponding letters are entered.
  • the distance C of the top of the cooling element 19 from the Bottom 8 of the upper end 7 e.g. 15 mm.
  • the preferred The size C range is 5 mm to 25 mm.
  • the length A of the cooling element 19 is preferred Example chosen with 205 mm, the preferred range for size A is 180 mm to 220 mm.
  • the distance D of the cooling element from the rear wall is preferably Fall 5 mm and a preferred range for size D is 1 mm to 15 mm.
  • the entry opening V is in the preferred case 19 mm, or the preferred range is 5 mm to 25 mm and is therefore the same size as the preferred range for the height C of the channel 12.
  • the length W of the element 14 is preferably 103 mm and is preferably in a range from 100 mm to 160 mm.
