Description
i 146875 1 Opfindelsen angår en kølet butiksdisk til udstilling og salg af levnedsmidler og af den i krav l's indledning angivne art.The invention relates to a refrigerated shop counter for the display and sale of foodstuffs and of the kind specified in the preamble of claim 1.
5 Por at kunne oplagre fordærvelige levnedsmidler og levnedsmidler, der skal holdes friske, såsom kød- og pølsevarer, ost, fint bagværk, grøntsager og frugt i længere tid, så de er synlige for kunderne, er det kendt at køle salgsdisken til levnedsmidlerne. På 10 grund af de store udstillingsrum, der for det meste er åbne opefter i sådanne diske er det teknisk ikke muligt at opnå en tilstrækkelig køling med køleplader eller fordamperindretninger, der arbejder med tyngde-kraftdrift. Man har derfor indbygget luftkøleindret-15 ninger for at tilføre den nødvendige kuldemængde til udstillingskanalen og dermed til levnedsmidlerne.5 To be able to store perishable foods and foods that need to be kept fresh, such as meat and sausage, cheese, fine pastries, vegetables and fruit for a long time so that they are visible to the customers, it is known to refrigerate the food sales counter. Due to the large exhibition spaces, which are mostly open up in such disks, it is technically not possible to obtain sufficient cooling with heat sinks or evaporators working with gravity power. Air-cooling devices have therefore been built-in to supply the required amount of cold to the show channel and thus to the food.
Fra fransk patent nr. 1.141.343 kendes en kølet butiksdisk, hvor der under en udstillingskanal er anbragt 20 en kølekanal med dyser, hvilken kølekanal kan afgive afkølet og befugtet luft til udstillingskanalen, idet dyserne er indrettet til at udsprøjte forstøvet, afkølet kølevæske. Den afkølede luft transporteres rundt i disken ved hjælp af en blæser.French Patent No. 1,141,343 discloses a refrigerated shop counter, where a cooling duct with nozzles is arranged under a display duct, which can supply cooled and humidified air to the show duct, the nozzles being arranged to spray atomized, cooled liquid. The cooled air is transported around the counter by means of a fan.
25 Sådanne konstruktioner har den ulempe, at den afkølede luft cirkuleres ved hjælp af en blæser.Such designs have the disadvantage that the cooled air is circulated by means of a fan.
Dette er energikrævende, og virker fordyrende på såvel selve disken som på diskens drift. Desuden kan den 30 kraftige luftstrømning, en sådan blæser frembringer, ofte rive kølevæskedråber med op i udstillingskanalen.This is energy intensive and is expensive on both the disk itself and on the disk's operation. In addition, the powerful air flow that such a fan produces can often tear coolant droplets up into the display duct.
Dette er uhensigtsmæssigt ved et stort antal af de varer, der kan tænkes anbragt i en sådan køledisk.This is inconvenient for a large number of the items that may be placed in such a cooling counter.
2 1Λ 6 8 7 5 1 Formålet med den foreliggende opfindelse er at an give en køledisk af den omhandlede art, ved hvilken de ovennævnte ulemper er undgået, idet en tilstrækkelig køling kan opnås uden anvendelse af ventilato-5 rer.The object of the present invention is to provide a cooling disk of the kind in which the above-mentioned drawbacks are avoided, as sufficient cooling can be obtained without the use of fans.
Dette opnås ifølge opfindelsen ved, at den kølede butiksdisk er udformet som angivet i krav l’s kendetegnende del.This is achieved according to the invention in that the refrigerated shop counter is designed as specified in claim 1's characteristic part.
1010
Ved denne udformning opnår man, at den afkølede luft vil presses ud af udløbsåbningen i kølekanalen ved hjælp af påvirkningen fra den under tryk udsprøjtede kølevæske . På grund af dette og på grund af den ejek-15 torvirkning, der opstår omkring dyserne, vil der i kølekanalens modsatte ende indsuges luft, således at kredsløbet er sluttet.In this embodiment, it is obtained that the cooled air will be forced out of the outlet opening in the cooling duct by means of the influence of the pressurized cooling liquid. Because of this and because of the ejector action that occurs around the nozzles, air at the opposite end of the cooling duct will suck in air so that the circuit is closed.
Ved det i krav 2 omhandlede opnås et kompakt og enkelt 20 system.The compact according to claim 2 provides a compact and simple system.
Ved det i krav 3 omhandlede opnås en hensigtsmæssig køledisk med adskillelse mellem udstillingsareal og kølesystem, samt med korte forbindelser for kølevæsken.In accordance with claim 3, an appropriate cooling disk is obtained with separation between the display area and the cooling system, as well as with short connections for the coolant.

Opfindelsen forklares i det følgende nærmere under henvis nine til teernineen. hvor fig. 1 viser en kendt køledisk, der som 30 teknikens stade danner udgangspunkt for opfindelsen, i tværsnit, fig. 2 viser på samme måde en foretrukken udførelsesform for køledisken ifølge opfindelsen, 146875 3 1 fig. 3 viser i mindre målestok en anden udførelsesform for opfindelsen, fig. 4 viser en yderligere udførelsesform for opfindelsen, og 5 fig. 5 viser en særlig fordelagtig ud førelsesform for køledisken med en i kølekanalen anbragt varme~ veksler.The invention is explained in greater detail below with reference to Nine to the teernine. FIG. 1 is a cross-sectional view of a known refrigeration disk which, as the state of the art, forms the basis of the invention; FIG. 2 shows a preferred embodiment of the cooling disk according to the invention; FIG. Figure 3 shows, on a smaller scale, another embodiment of the invention; 4 shows a further embodiment of the invention; and FIG. 5 shows a particularly advantageous embodiment of the cooling disk with a heat exchanger arranged in the cooling channel.
10 En sådan kendt butiksdisk er vist på fig. 1 i forenklet form til anskueliggørelse af teknikkens stade.10 Such a known shop counter is shown in FIG. 1 in simplified form to illustrate the state of the art.
Et disklegeme, der er udformet forskelligt fra tilfælde til tilfælde, er betegnet med l, en arbejdsplade med 2, en varetilførsels- og tælleplade med 3 15 og en glasskive, der dækker varer 6 i forhold til kunderne, og gennem hvilken man kan se, er betegnet med 4. Derved kan varer 6 ses af kunderne i en udstillingskanal 5. Til køling af varen 6 bliver luft i udstillingskanalen 5 indsuget ved hjælp af en luft- 20 transportindretning 7 gennem åbninger 9a, ført over en kølefordamper eller en varmeveksler 8 og derefter gennem åbninger 9 ledet tilbage til udstillingskanalen 5. Luften i udstillingskanalen 5 bliver altså udskiftet efter et cirkulationsprincip og derved kølet til 25 den krævede temperatur fra +2 til -8°C. Varmeveksleren 8 er forbundet med en gængs kølemaskine. Por at hindre temperaturgennemgang er luftføringen i disken 1 udefter forsynet med en isolation 10.A disc body, designed differently on a case-by-case basis, is denoted by l, a workplate of 2, a product supply and counting plate of 3 15, and a glass disk covering goods 6 in relation to customers and through which one can see, is indicated by 4. Thereby, goods 6 can be seen by the customers in an exhibition duct 5. For cooling the goods 6, air in the exhibition duct 5 is sucked in by means of an air transport device 7 through openings 9a, passed over a cooling evaporator or a heat exchanger 8 and then, through openings 9, lead back to the display duct 5. The air in the display duct 5 is thus changed according to a circulation principle and thereby cooled to the required temperature from +2 to -8 ° C. The heat exchanger 8 is connected to a conventional cooling machine. To prevent temperature passage, the air duct in disk 1 is provided with an insulation 10 outwards.
30 I fig. 2 er et disklegeme 1 på sædvanlig måde udstyret med en arbejdsplade 2, en tilførsels- og tælleplade 3, en glasskive 4 og en isolation 10 om en kølekanal 13. I kølekanalen 13 er der ifølge opfindelsen i stedet for en sædvanlig varmeveksler anbragt en fordeler 14 ij 146875 1 for kølevæske l6, der fordeles frit gennem dyser 15, fortrinsvis forstøves fint. Denne kølede væske 16 bliver kølet af en sædvanlig kølemaskine l8 i en varmeveksler 17 til en ønsket temperatur. En pumpe 19 over-5 tager transporten af kølevæsken l6, der, efter at den har passeret dyserne 15 og er strømmet gennem kølekanalen 13, strømmer tilbage til en samlebeholder 20.In FIG. 2, a disc body 1 is conventionally provided with a work plate 2, a supply and counting plate 3, a glass disc 4 and an insulation 10 about a cooling duct 13. In the cooling duct 13, according to the invention, a distributor 14 is arranged instead of a conventional heat exchanger. Preferably, coolant 16 distributed freely through nozzles 15 is preferably nebulized. This cooled liquid 16 is cooled by a conventional chiller 18 in a heat exchanger 17 to a desired temperature. A pump 19 over-takes the transport of the coolant 16, which, after passing the nozzles 15 and flowing through the cooling duct 13, flows back to a collecting vessel 20.
Denne samlebeholder kan være udstyret med gængse filtre, efterfyldningsindretninger og lignende orga-10 ner. Ved udsprøjtningen af kølevæsken 16 frembringes der i kølekanalen 13 et opstuvningstryk, der transporterer den i kølekanalen 13 værende luft gennem åbninger 9 ind i udstillingskanalen 5. Samtidig opstår der ved åbningen 9a en ejektorvirkning, ved 15 hjælp af hvilken luften i udstillingskanalen 5 atter tilsuges ved disse åbninger 9a og derved sættes i en cirkulerende rotationsbevægelse. Under indsprøjtningen af kølevæsken 16 bliver luften afkølet til den ønskede temperatur, idet der ved den direkte 20 kontakt mellem luft og kølevæske er sikret en maksimal mulig befugtning. Kræves der i udstillingskanalen 5 temperaturer på fx 4 til 6°C, er det tilstrækkeligt, når kølevæsken 16 har en temperatur på lidt over 0°C. Kræves der lavere temperaturer, kan der også 25 anvendes en kølevæske på under 0°C.This collector can be fitted with conventional filters, backfill devices and similar devices. When the coolant 16 is sprayed, a cooling pressure is produced in the cooling duct 13 which transports the air present in the cooling duct 13 through openings 9 into the exposition duct 5. At the same time, at the opening 9a an ejector effect is generated, by which the air in the duct duct 5 is again sucked at these apertures 9a thereby being put into circulating rotary motion. During the injection of the coolant 16, the air is cooled to the desired temperature, with the maximum possible humidification ensured by the direct contact between air and coolant. If temperatures of, for example, 4 to 6 ° C are required in the display channel 5, it is sufficient when the coolant 16 has a temperature of just over 0 ° C. If lower temperatures are required, a coolant below 0 ° C may also be used.
Det er nærliggende, at der som kølevæske anvendes vand, hvis frysepunkt så må nedsættes. Det er tilstrækkeligt med en tilsætning af kogsalt eller en 30 anden egnet tilsætning, der kan tåles af levnedsmidlerne eller er neutral. Da der ved indsprøjtningen af kølevæsken 16 opnås en løbende rensningseffekt i kølekanalen 13,. kan kanalafdækningen 12 også være indbygget fast. Eventuelt medtaget støv og smudsdele i den 5 146875 1 gennem åbningerne 9a indsugede luft bliver bundet af kølevæsken 16 og udfiltreret i samlebeholderen 20.It is obvious that water is used as a coolant, whose freezing point must then be reduced. It is sufficient for an addition of boiling salt or another suitable addition which can be tolerated by the foodstuffs or is neutral. As the cooling liquid 16 is injected, a continuous cleaning effect is obtained in the cooling duct 13. for example, the duct cover 12 may also be fixed in place. Optionally, dust and dirt parts included in the air sucked in through the openings 9a are bound by the coolant 16 and filtered out in the collecting container 20.
Med det i fig. 2 skematisk viste arbejdsprincip sparer 5 man ikke blot en lufttransportindretning 7, men man opnår også en konstant holdt temperatur af luften i udstillingskanalen 5 med en total fugtighedsmætning og fuldkommen frihed for støv og smuds. Den udstillede vare 6 i udstillingskanalen 5 er ved en sådan 10 drevet disk ikke udsat for nogen udtørring, og kan også ved konstant temperatur og med en hygiejnisk upåklagelig støv- og smudsfiltreret køleluft oplagres frisk i lang tid. Desuden sparer betjeningen den ellers nødvendige løbende rengøring af kølekanalen 15 13, hvortil også hører en udtagelse af varerne 6 og af kanalafdækningen 12.Referring to FIG. 2 schematically illustrated working principle 5 not only saves air transport device 7, but also achieves a constant temperature of the air in exhibition channel 5 with a total humidity saturation and complete freedom from dust and dirt. The exhibited product 6 in the display channel 5 is not subjected to any drying at such a driven disk 10, and can also be stored fresh for a long time at a constant temperature and with a hygienically impeccable dust and dirt-filtered cooling air. In addition, the operation saves the otherwise necessary continuous cleaning of the cooling duct 15 13, which also includes a removal of the goods 6 and of the duct cover 12.
Til opnåelse af effekten ved disken ifølge opfindelsen er det naturligvis uden betydning, om varmeveksleren 20 17 med pumpen 19, samlebeholderen 20 og kølemaskinen 18 bliver anbragt inden i eller uden for salgsdisken 1.Obviously, in order to achieve the effect of the disc according to the invention, it is irrelevant whether the heat exchanger 20 17 with the pump 19, the collecting container 20 and the cooling machine 18 is placed inside or outside the sales counter 1.
Den i fig. 3 viste udførelsesform arbejder med det 25 modsatte princip af formen af udførelsesformen i fig.The FIG. 3 illustrates the opposite principle of the shape of the embodiment of FIG.
2, men er ellers opbygget på samme måde, idet alene strømningsretningen for kølevæsken 16 er den modsatte.2, but is otherwise constructed in the same way, with the flow direction only for the coolant 16 being the opposite.
Den kølede, fugtede og støvfri luft bliver ved hjælp af påvirkningen fra det under tryk udsprøjtede køle-30 middel 16 trykket hen til åbningerne 9a i udstillingskanalen 5 og atter indsuget gennem åbningerne 9, hvorved kredsløbet er lukket.The cooled, humidified and dust-free air is pressurized to the openings 9a of the display duct 5 by means of the influence of the pressurized refrigerant 16, which is again sucked through the openings 9, thereby closing the circuit.
Udførelsen i fig. 4 afviger fra det ovenfor beskrevne . ved, at kølevæsken l6 på bunden af kølekanalen 13 med 146875 6 1 fri overflade og af en kølemaskine l8 ved hjælp af en varmeveksler 17 bringes på den ønskede temperatur.The embodiment of FIG. 4 differs from that described above. in that the coolant l6 on the bottom of the cooling duct 13 with free surface and of a cooling machine l8 by means of a heat exchanger 17 is brought to the desired temperature.
Pumpen 19 forsyner fordeleren 14, hvor kølevæsken gennem dyser 15 sprøjtes ind i kølekanalen 13. Den 5 øvrige funktionsmåde er den samme som ved udførelserne i fig. 2 og 3.The pump 19 supplies the distributor 14, where the coolant is injected through nozzles 15 into the cooling duct 13. The other mode of operation is the same as in the embodiments in fig. 2 and 3.
Den i fig. 5 viste udførelsesform betyder en fordelagtig videre udvikling af opfindelsen. Varmeveksleren 10 17 er anbragt i kølekanalen 13 og strækker sig i læng deretningen af butiksdisken omtrent over hele længden.The FIG. 5 shows an advantageous further development of the invention. The heat exchanger 10 17 is arranged in the cooling duct 13 and extends in the longitudinal direction of the shop counter approximately the entire length.
Dyserne 15 er fordelt på ens afstande i længden af varmeveksleren 17 og integreret med denne. Denne udformning er særlig fordelagtig, fordi varmeveksleren 15 på grund af sin anbringelse i kølekanalen ikke mere behøver at isoleres udefter, og fordi endvidere de ellers nødvendige tilledninger mellem varmeudveksle-ren 17 og dyserne 15 falder bort, hvilke tilledninger ellers også måtte isoleres.The nozzles 15 are distributed at equal distances in the length of the heat exchanger 17 and integrated therewith. This design is particularly advantageous because the heat exchanger 15, due to its placement in the cooling duct, no longer needs to be insulated outwardly and because the otherwise necessary connections between the heat exchanger 17 and the nozzles 15 are lost, which otherwise would have to be insulated.
2020
Opfindelsen kan også anvendes, med bibeholdelse af dens fordelagtige virkninger, når den overføres til lukkede diske, trug eller skabe.The invention may also be used, while retaining its beneficial effects when transferred to closed disks, troughs or cabinets.
