Description
Den foreliggende oppfinnelse vedrører en anordning ved kjøledisk, f.eks. kafeteriadisk, ferskvare-salgsdisk e.l., der disken har bakvegg (betjeningsside), sidevegger, tak, bunn, og i det minste delvis åpent frontparti (kundeside), der midler er tilveiebragt for å la kjøleluft strømme over matvarene ned fra et parti ved taket, der bunnen eventuelt er forsynt med et bortsugparti for kjøleluften, og der taket er utformet med et første kanalutstyr for å dirigere kjøleluft ned over matvarene og et andre kanalutstyr for dirigering av en luftstrøm med romtemperatur nedad fra et frontparti av taket og over det åpne frontpartiet for derved å danne et luftgardin. The present invention relates to a device at a refrigerator, e.g. cafeteria counter, fresh food sales counter etc., where the counter has a back wall (service side), side walls, roof, bottom, and at least a partially open front part (customer side), where means are provided to allow cooling air to flow over the food products down from a section near the roof, where the bottom is optionally provided with an extraction section for the cooling air, and where the roof is designed with a first channel device for directing cooling air down over the food and a second channel device for directing an air flow with room temperature downwards from a front part of the roof and over the open front part for thereby forming an air curtain.
Fra tidligere er det kjent at kjøledisker, særlig i kafeteriaer, ofte er blitt forsynt med deksler på kundesiden av disken, slik at kjøleluften ikke skal slippe ut nær det sted der kundene står. Dekslene har vært nødvendige for å bevirke effektiv kjøling. Bruken av deksler eller luker på kundesiden ofte oppleves ofte som tungvint for brukeren, og likeledes også ofte for betjeningen med tanke på renhold. It is known from the past that refrigerated counters, especially in cafeterias, have often been provided with covers on the customer side of the counter, so that the cooling air should not escape near the place where the customers are standing. The covers have been necessary to effect effective cooling. The use of covers or hatches on the customer side is often experienced as cumbersome for the user, and likewise often for the operator in terms of cleaning.
I supermarkeder er det ofte vanlig å la kjøleluft strømme ned over f.eks. grønnsaker, gjerne befuktet kjøleluft, men ofte vil kjøleluften ved lagringsåpningens nedre kant strømme ut forbi kant og ned mot gulvet, eller varm luft fra rommet vil sige inn mot grønnsakene og heve temperaturen til over det som tillates, dvs. maks. +7° C. In supermarkets, it is often customary to allow cooling air to flow down over e.g. vegetables, preferably humidified cooling air, but often the cooling air at the lower edge of the storage opening will flow out past the edge and down towards the floor, or warm air from the room will seep in towards the vegetables and raise the temperature to above what is permitted, i.e. max. +7° C.
Den foreliggende oppfinnelse tar derfor sikte på å løse disse kjente problemer på en enkel og effektiv måte, og ifølge oppfinnelsen kjennetegnes derfor anordningen ved at bakveggen består av to innbyrdes bevegelige, hule skyvedører som er åpne i henholdsvis overkant og underkant, der den første skyvedør er innrettet til å lede via sitt hulrom romtemperert luft utmatet fra et vifteaggregat opp til det andre kanalutstyret, og der den andre skyvedøren er innrettet til å lede via sitt hulrom kjøleluft tvangsutmatet fra en fordamper opp til det første kanalutstyret. The present invention therefore aims to solve these known problems in a simple and effective way, and according to the invention the device is therefore characterized by the fact that the rear wall consists of two mutually movable, hollow sliding doors which are open at the top and bottom respectively, where the first sliding door is arranged to direct via its cavity room-temperature air discharged from a fan unit up to the second duct equipment, and where the second sliding door is arranged to direct via its cavity cooling air forcibly discharged from an evaporator up to the first duct equipment.
I en spesiell utførelse kan skyvedørene gjøres innbyrdes teleskoperbare i horisontal retning, idet den andre døren i tverrsnitt fortrinnsvis gis tilnærmet n -form og den første døren i tverrsnitt fortrinnsvis gis tilnærmet [] -form, idet et vertikalt endeparti av den første døren dermed samtidig danner et forflyttbart, vertikalt endeparti i den andre døren. In a special embodiment, the sliding doors can be made mutually telescopable in the horizontal direction, with the second door in cross-section preferably being approximately n-shaped and the first door in cross-section preferably being approximately []-shaped, with a vertical end part of the first door thus simultaneously forming a movable, vertical end part in the second door.
Ifølge en annen utførelseform utgjøres nevnte første og andre kanalutstyr av en luftdistribusjonsenhet bestående av henholdsvis en øvre kanaliseringsdel som har inntak for rom-temperert luft langs en første del av enhetens bakre parti og en nedre kanaliseringsdel som har inntak for nedkjølet luft langs en andre del av enhetens bakre parti. According to another embodiment, said first and second duct equipment is made up of an air distribution unit consisting respectively of an upper ducting part which has an intake for room-tempered air along a first part of the rear part of the unit and a lower ducting part which has an intake for cooled air along a second part of the rear part of the unit.
Oppfinnelsen skal nå nærmere forklares under henvisning til de vedlagte tegninger. The invention will now be explained in more detail with reference to the attached drawings.

I fig. 1 og 2 er vist, som eksempel, en typisk kjøledisk, særlig for kafeteria-formål. Disken 1 har bakvegg 2, sidevegger 3, 4, tak 5, bunn 6, og i det minste delvis åpent frontparti 7. In fig. 1 and 2 show, as an example, a typical refrigerated counter, particularly for cafeteria purposes. The disk 1 has a back wall 2, side walls 3, 4, roof 5, bottom 6, and at least a partially open front part 7.
Midler i form kjøleaggregat 8 med utblåsningsvifte 20 , samt første kanalutstyr 10 (se fig. 3 og 4) er tilveiebragt for å la kjøleluft strømme dirigert over matvarene (ikke vist) ned fra et parti 10"'ved taket 5. Kjølediskens bunn 6 er eventuelt er forsynt med et bortsugparti 12 for kjøleluften, fortrinnsvis anbragt ved bunnens forkant. Det er også mulig å anbringe en brønn 6' i bunnen 6. I kjøleaggregatet 8 inngår en fordamper 8', og vannavløp 8" derfra fører til vanlig spillvannsutslipp (ikke vist). Means in the form of cooling unit 8 with exhaust fan 20, as well as first channel equipment 10 (see fig. 3 and 4) are provided to allow cooling air to flow directed over the food (not shown) down from a section 10"' at the ceiling 5. The bottom of the cooling counter 6 is is optionally provided with a suction part 12 for the cooling air, preferably placed at the front edge of the bottom. It is also possible to place a well 6' in the bottom 6. The cooling unit 8 includes an evaporator 8', and water drain 8" from there leads to normal waste water discharge (not shown).
Et andre kanalutstyr 14 er anordnet for dirigering av en luftstrøm 11 med romtemperatur nedad fra et frontparti 5' av taket 5 og over det åpne frontpartiet 7 for derved med denne styrte luftstrøm SRL å danne et luftgardin LG. Det andre kanalutstyret 14 innbefatter med fordel en nedad buet ledeplate 15 anbragt ved takets 5 front 5'. A second channel device 14 is arranged for directing an air flow 11 at room temperature downwards from a front part 5' of the roof 5 and over the open front part 7 in order thereby to form an air curtain LG with this controlled air flow SRL. The second channel equipment 14 advantageously includes a downwardly curved guide plate 15 placed at the front 5' of the roof 5.
Nevnte første 10 og andre 14 kanalutstyr utgjøres, ifølge en foretrukket utførelsesform av en luftdistribusjonsenhet 16 bestående av en øvre luftkanaliseringsdel 14' som har inntak 14" for romtemperert luft langs en første del 16' av enhetens bakre parti og en nedre kanaliseirngsdel 10' som har inntak 10" for nedkjølet luft langs en andre del 16" av enhetens 16 bakre parti. Kanalutstyret 10 vil danne et tilnærmet trykkammer og er utstyrt med perforert plate 10"' for finfordeling av nedkjølet luft KL i full lengde av kjøledisken 1 som styrt kjøleluft SKL. Mellom nedre del 10' og øvre del 14' foreligger en skillevegg 16'". Ved fremkant av den øvre delen er det anbragt en perforert plate 14"' for fordeling av romluftstrømmen RL, slik at den kan strømme videre som styrt romluft SRL Said first 10 and second 14 duct equipment is constituted, according to a preferred embodiment, by an air distribution unit 16 consisting of an upper air channeling part 14' which has an intake 14" for room-temperature air along a first part 16' of the rear part of the unit and a lower ducting part 10' which has intake 10" for cooled air along a second part 16" of the rear part of the unit 16. The duct equipment 10 will form an approximate pressure chamber and is equipped with a perforated plate 10"' for fine distribution of cooled air KL in the full length of the cooling disk 1 as controlled cooling air SKL . Between the lower part 10' and the upper part 14' there is a partition wall 16'". At the leading edge of the upper part, a perforated plate 14"' is placed for distribution of the room air flow RL, so that it can flow on as controlled room air SRL
Bakveggen består av to innbyrdes bevegelige , hule skyvedører 17,18 som er åpne i henholdsvis overkant og underkant. Den første skyvedøren 17 er innrettet til å lede via sitt hulrom 17' romtemperert luft utmatet fra et vifteaggregat 9 opp til nevnte første del 16' av enhetens 16 bakre parti. Den andre skyvedøren 18 er innrettet til å lede via sitt hulrom 18' kjøleluft utmatet ved hjelp av en vifte 20 fra kjøleaggregatets 8 fordamper 8' opp til nevnte andre del 16" av enhetens 16 bakre parti. For å kunne lage så plan bakvegg som mulig, samt å hindre at den første skyvedøren inntar den andre skyvedørens plass og omvendt, hvorved lufttransporten eventuelt kan opphøre, foreslås det at skyvedørene gjøres innbyrdes teleskoperbare i horisontal retning. Ved en slik løsning har fortrinnsvis den andre døren 18 i tverrsnitt tilnærmet n -form og den første døren 17 har i tverrsnitt fortrinnsvis tilnærmet [] -form. Dermed vil også et vertikalt endeparti 17" av den første døren samtidig danne et forflyttbart, vertikalt endeparti i den andre døren 18. Skyvedørene er med fordel utformet med varmeisolerende sideflater. Videre er skyvedørene 17,18 med fordel forskyvbare i glidespor 21 på disken 1. The rear wall consists of two mutually movable, hollow sliding doors 17,18 which are open at the top and bottom respectively. The first sliding door 17 is designed to conduct via its cavity 17' room-temperature air discharged from a fan unit 9 up to said first part 16' of the rear part of the unit 16. The second sliding door 18 is arranged to conduct via its cavity 18' cooling air discharged by means of a fan 20 from the cooling unit's 8 evaporator 8' up to the aforementioned second part 16" of the rear part of the unit 16. In order to create as flat a rear wall as possible , as well as to prevent the first sliding door from taking the place of the second sliding door and vice versa, whereby the air transport may eventually cease, it is proposed that the sliding doors be made mutually telescopable in the horizontal direction. With such a solution, the second door 18 preferably has an approximately n-shape in cross-section and the first door 17 preferably has an approximately [] shape in cross-section. Thus, a vertical end part 17" of the first door will also simultaneously form a movable, vertical end part in the second door 18. The sliding doors are advantageously designed with heat-insulating side surfaces. Furthermore, the sliding doors 17,18 are advantageously displaceable in sliding tracks 21 on the disk 1.
Viftene 9 og 20 er fortrinnsvis dobbeltsugende radialvifter, eventuelt utstyrt med tyristorstyring, og utblåsningsåpningene 9' og 20' fra viftene munner ut i glidesporet, slik som vist på fig. 4. The fans 9 and 20 are preferably double-suction radial fans, optionally equipped with thyristor control, and the exhaust openings 9' and 20' from the fans open into the sliding track, as shown in fig. 4.
Det vil umiddelbart forstås at det innenfor rammen av de etterfølgende krav vil være mulig for fagmannen å foreta modifikasjoner og/eller anvende teknisk ekvivalente hjelpemidler. It will immediately be understood that within the scope of the subsequent requirements it will be possible for the skilled person to make modifications and/or use technically equivalent aids.
