Opfindelsen angår en køleboks med vandret åbning og af den i indledningen til krav 1 angivne art. Denne køleboks er egnet til at danne et led i en kæde til fordeling af varer, som kun kan holde sig friske, hvis de opbevares ved køleskabs-5 temperatur.The invention relates to a cooling box with a horizontal opening and of the kind specified in the preamble of claim 1. This refrigerator is suitable for forming a link in a chain for distribution of goods which can only stay fresh if stored at refrigerator temperature.
Blandt varer med ovennævnte egenskaber kan nævnes farmaceutiske præparater, såsom vaccine, og levnedsmidler, såsom fisk. Der findes store mængder sådanne varer, der fra et centralt sted 10 via et net skal fordeles til forbrugere på store afstande.Among the products having the above mentioned properties are pharmaceutical preparations such as vaccine and foodstuffs such as fish. There are large quantities of such goods that must be distributed to consumers at great distances from a central location 10 via a network.
Til denne fordeling anvendes kølevogne og undercentraler med kølelagre. Disse har hidtil været afhængige af elektrisk strømforsyning til deres virksomhed, og fordelingsnettet for f.eks. vaccine har derfor måttet begrænses til områder med et sådant 15 forsyningssystem. Det er imidlertid netop indenfor de områder, som ligger udenfor det elektriske net, hvor f.eks. en forsyning med vaccine er særlig ønskelig.Refrigerators and sub-stations with cold stores are used for this distribution. These have so far depended on electric power supply for their business, and the distribution network for e.g. vaccine has therefore had to be restricted to areas with such a supply system. However, it is precisely within those areas which are outside the electrical grid, where e.g. a supply of vaccine is particularly desirable.
Til at løse denne opgave foreslås ifølge opfindelsen en køle- 20 boks, der muliggør ikke blot en længere lagring af varer ved en passende temperatur under betingelser, hvor elektrisk strømtilførsel savnes, men også ladning og lagring af kuldeakkumulatorer til brug ved fordeling af varer fra køleboksen til de enkelte forbrugere.In order to solve this task, the invention proposes a cooling box which allows not only longer storage of goods at an appropriate temperature under conditions where electric power supply is missing, but also charging and storage of cold accumulators for use in distributing goods from the cooling box. to individual consumers.

For at tilgodese dette formål er køleboksen ifølge opfindelsen ejendommelig ved det i den kendetegnede del af krav 1 anførte.In order to meet this purpose, the refrigerator according to the invention is characterized by the part of claim 1.
Herved bliver håndteringen af kuldeakkumulatorer enkel; uden at de hindrer håndteringen af varer i kurven. Akkumulatorerne 30 anbringes først i kammeret mellem kurven med varerne og den kølede flade i kontakt med sidstnævnte, således at akkumulatorernes nedfrysning sker hurtigt. Derefter slippes akkumulatorerne ned på boksens bund, hvor de opbevares indtil de skal tages ud og benyttes til senere køleformål uden at hindre 35 håndtering af varer i kurven.This makes handling cold accumulators simple; without hindering the handling of items in the basket. The accumulators 30 are first placed in the chamber between the goods basket and the chilled surface in contact with the latter, so that the accumulators freeze rapidly. Then the accumulators are dropped onto the bottom of the box where they are stored until they are taken out and used for later cooling purposes without hindering the handling of items in the basket.
Ifølge en videre udvikling af den foreliggende opfindelse er denne ejendommelig ved, at en fjeder er anbragt til atAccording to a further development of the present invention, this is characterized in that a spring is arranged to

holde kuldeakkumulatoren i kontakt med fladen. Herved kan de nedfrosne akkumulatorer ganske enkelt overføres til det nedre kammer ved,at man blot trykker dem ned.keep the cold accumulator in contact with the surface. In this way, the frozen accumulators can simply be transferred to the lower chamber by simply pushing them down.
t 5 Opfindelsen forklares nedenfor under henvisning til tegningen, hvor fig. 1 viser et lodret tværsnit gennem en afkølet boks, 10 fig. 2 boksen i fig. 1, set fra oven med låget opslået.The invention is explained below with reference to the drawing, in which fig. 1 shows a vertical cross section through a cooled box; FIG. 2 shows the box of FIG. 1, viewed from above with the lid open.
Da klimaet er meget varmt i mange af de områder, hvor det er aktuelt at anvende opfindelsen til vaccinefordeling, er en køleboks1 vægge 10, 11, bund 12 og låg 13 forsynet med 15 en effektiv isolering. Isoleringen kan være polyurethanskum, der indeholder en tung gas. Låget 13 er ved hængsler 14 fastgjort til bcksen og har et håndtag 15. Boksens underbeklædning 16 er dannet af en varmeledende plade af et egnet materiale, medens dens yderbeklædning 17 kan bestå af metalplade, 20 plast eller et andet egnet materiale. Laget 13 har en rundt om boksens åbning gående pakning 18.As the climate is very hot in many of the areas where it is appropriate to use the invention for vaccine distribution, a cooling box1 walls 10, 11, bottom 12 and lid 13 are provided with effective insulation. The insulation may be polyurethane foam containing a heavy gas. The lid 13 is secured to the box by hinges 14 and has a handle 15. The box's undercoat 16 is formed of a heat-conducting plate of a suitable material, while its outer covering 17 may consist of metal plate, 20 plastic or other suitable material. Layer 13 has a gasket 18 extending around the box opening.
Køleboksen er udstyret med et brænderdrevet absorptionskøleapparat, som kan være af i og for sig kendt type og derfor 25 ikke vises i detaljer på tegningen. Køleapparatet har en fordamper i form af en rørslange 19, som er anbragt inde i den ene boksvæg 10 og som er i varmeledende kontakt med underbeklædningen 16. Fordamperen 19 er anbragt relativt højt på vægoverfladen og arbejder ved en temperatur, som givetvis 30 er afhængig af omgivelsernes temperatur, men som dog bør ligge omkring -20°C. Hvis omgivelserne om dagen har en meget høj temperatur, kan det indtræffe, at fordamperens temperatur stiger, men om natten hersker der som regel en betragtelig lavere omgivelsestemperatur, og så falder fordamperens tempera-35 . - tur også. Nar det drejer sug om temperaturen i boksens opbevaringsrum modvirkes disse svingninger i fordampertemperaturen af boksens meget kraftige varmeisolering, så at temperaturen i boksen ikke varierer så meget som fordampertemperaturen.The cooling box is equipped with a burner-driven absorption cooling apparatus, which may be of a type known per se and therefore not shown in detail in the drawing. The refrigerator has an evaporator in the form of a tube hose 19 which is disposed inside one box wall 10 and which is in heat conductive contact with the undercoat 16. The evaporator 19 is placed relatively high on the wall surface and operates at a temperature which, of course, is dependent on 30 ambient temperature, but which should nevertheless be around -20 ° C. If the environment during the day has a very high temperature, the evaporator temperature may rise, but at night there is usually a considerably lower ambient temperature, and then the evaporator temperature drops. - trip too. When it comes to suction the temperature in the box storage room, these oscillations in the evaporator temperature are counteracted by the very strong thermal insulation of the box, so that the temperature in the box does not vary as much as the evaporator temperature.

Parallelt med væggen 10, hvori fordamperen 19 er anbragt, er der en varmeisolerende skive 20. Denne forløber mellem køleboksens to endevægge 21, 22 og fra dens åbningsplan 23 nedad til lidt over halvdelen af boksens dybde. I boksen erParallel to the wall 10, in which the evaporator 19 is arranged, is a heat insulating disc 20. This extends between the two end walls 21, 22 of the cooling box and from its opening plane 23 downwards to just over half the depth of the box. In the box is

en metalplade anbragt mod den vægflade, ved hvilken fordamperen 19 ligger. Pladen har en plan del 24, der ligger an mod væg-overfladen og en nedre buet del 25. Mod den varmeisolerende skive 20's overflade er der rettet en eller flere bladfjedre 26. Den varmeisolerende skive 20 er anbragt og fjedrene 26 er 10 afpasset således, at der nabostillet til den plane pladedel 24 dannes et langt, smalt kammer 27 til optagelse af en række kuldeakkumulatorer 28, der af fjedrene 26 holdes trykket mod vægoverfladen.a metal plate disposed against the wall surface on which the evaporator 19 lies. The plate has a flat portion 24 abutting the wall surface and a lower curved portion 25. One or more leaf springs 26 are directed against the surface of the heat-insulating disc 20. The heat-insulating disc 20 is arranged and the springs 26 are adapted so as to that a long narrow chamber 27 is formed adjacent to the planar plate portion 24 for receiving a series of cold accumulators 28 which are held by the springs 26 pressed against the wall surface.

Kuldeakkumulatorene 28 er flade og kan være af i og for sig kendt type. Når køleboksen benyttes til transport af vaccine, kan de indeholde en opløsning med et frysepunkt ved fra ca.The cold accumulators 28 are flat and may be of a type known per se. When used for transporting the vaccine, the cooler can contain a solution with a freezing point at from approx.
-2 til -4°C.-2 to -4 ° C.
20 Når en række kuldeakkumulatorer 28 er blevet opladet, trykker man dem ned imod virkningen af fjedrene 26, forbi en vinkelhylde 29 på pladerne 24, 25, så at de falder ned i boksens anden enhed, som består af et kammer 30 over boksens hele bundflade. Dette rum modtager ingen direkte afkøling fra køle-apparatet, da fordamperen 19 er anbragt i kontakt med en flade højt oppe på væggen i kammeret 27, men det afkøles dels ved, at det indeholder allerede ladede akkumulatorer med lav temperatur, dels ved luftstrømning fra kammeret 27, hvor luften er meget kold.20 When a number of cold accumulators 28 have been charged, they are pressed down against the action of the springs 26, past an angle shelf 29 on the plates 24, 25, so that they fall into the second unit of the box, which consists of a chamber 30 over the entire bottom surface of the box. . This room receives no direct cooling from the cooling apparatus as the evaporator 19 is placed in contact with a surface high up on the wall of the chamber 27, but it is cooled partly by containing already low temperature accumulators and partly by air flow from the chamber. 27, where the air is very cold.

Som det fremgår af fig. 1 indeholder boksen et tredje kammer 31, som heller ikke afkøles direkte af køleapparatet. I dette tredje kammer opbevares vaccinepakninger 32 eller levnedsmidler i en kurv 33, hvis ene side er ophængt på bokskanten eller 35 i en speciel holder 34 og med den anden side på den isolerede skive 20. Kammeret 31 afgrænses fra det andet derunder beliggende kammer 30 af et lag kuldéakkumulatorer 28.As shown in FIG. 1, the box contains a third chamber 31 which is not directly cooled by the refrigerator. In this third chamber, vaccine packs 32 or foodstuffs are stored in a basket 33, one side of which is suspended on the box edge or 35 in a special holder 34 and with the other side on the insulated disc 20. The chamber 31 is delimited from the other chamber 30 located below it. a layer of carbon accumulators 28.

Med den ovenfor beskrevne boks har det vist sig muligt, at opbevare varer i det tredje kammer 31 ved køleskabstemperatur, dvs. omkring +4°C,i lang tid og samtidig lade et antal kuldeakkumulatorer i det første kammer 27 for.derefter at lagre, 5 disse kuldeakkumulatorer i det andet kammer 30 ved en temperatur, som ligger noget under frysepunktet. På denne måde kan man dels muliggøre den ønskede opbevaring af vårene i boksen, dels lade en så stor mængde kuldeakkumulatorer, at man ved anvendelse af disse og uden adgang til noget køleapparat kan 10 fordele vårene til forbrugerne. Til den efterfølgende transport kan anvendes en lille velisoleret boks, hvis bund og vægge fores med ladede kuldeakkumulatorer. Vårene anbringes i boksen, og derefter tildækkes de med et lag af kuldeakkumulatorer inden boksens låg lægges på. Med denne udrustning kan vårene 15 transporteres i flere dage, endog i et meget varmt klima.With the box described above, it has been found possible to store goods in the third chamber 31 at refrigerator temperature, ie. about + 4 ° C, for a long time, and at the same time allow a number of cold accumulators in the first chamber 27 to subsequently store these 5 cold accumulators in the second chamber 30 at a temperature which is somewhat below freezing. In this way, one can make possible the desired storage of the spring in the box, and partly allow such a large amount of cold accumulators that by using these and without access to any refrigeration apparatus, the spring can be distributed to the consumers. For the subsequent transport a small well-insulated box can be used, the bottom and walls of which are lined with charged cold accumulators. The springs are placed in the box and then covered with a layer of cold accumulators before the box lid is applied. With this equipment, the spring 15 can be transported for several days, even in a very hot climate.
