Opfindelsen angår et apparat af den i indledningen til krav 1 nævnte art til fremstilling af isterninger.The invention relates to an apparatus of the kind mentioned in the preamble of claim 1 for making ice cubes.

Apparater, der hurtigt og kontinuerligt kan fremstille brugsklare isterninger, bliver mere og mere almindelige.Devices that can quickly and continuously produce ready-to-use ice cubes are becoming more and more common.

5 Nogle af disse er baseret på, at korte parallelle forgreninger, der rager frem fra en kølekredsløbsfordamper, holdes nedsænket i et vandbassin. Vandet kondenserer på forgreningerne, hvorved der dannes isterninger, som med mellemrum fjernes ved, at vandbassinet vendes og 10 fordamperens arbejdsgang reverseres.5 Some of these are based on the fact that short parallel branches protruding from a cooling circuit evaporator are kept immersed in a water basin. The water condenses on the branches, forming ice cubes which are occasionally removed by reversing the water basin and reversing the evaporator's workflow.

Andre mere moderne apparater har på den anden side elimineret vandbassinet, og fordamperens forgreninger (eller ækvivalente vendte kølekopper) rammes direkte af meget tynde stråler af forstøvet vand, som sendes opad gennem 15 meget små huller i en gruppe små rør. I dette tilfælde fjernes terningerne udelukkende ved reversering af fordamperens arbejdsgang.Other more modern appliances, on the other hand, have eliminated the water basin, and the evaporator's branches (or equivalent inverted cooling cups) are directly hit by very thin jets of atomized water, which are sent upward through 15 very small holes in a group of small pipes. In this case, the dice are removed only by reversing the evaporator operation.

Apparater af den sidstnævnte art er utvivlsomt enklere, men på den anden side kan der opstå problemer med bloke-20 ring af forstøvningshullerne på grund af det lille tværsnit, som er nødvendigt til forstøvningen.Apparatus of the latter kind is undoubtedly simpler, but on the other hand, problems can be encountered with blocking the nebulization holes due to the small cross section necessary for the nebulization.

Formålet med opfindelsen er at angive et apparat til fremstilling af isterninger, som er yderst enkelt, og som samtidigt, ikke er behæftet med driftsproblemerne af den nævn-2^ te art.The object of the invention is to provide an apparatus for making ice cubes which is extremely simple and which, at the same time, is not beset with the operating problems of the said kind.

Dette formål opnås ifølge opfindelsen ved, at det indledningsvis nævnte apparat er ejendommeligt ved det i den kendetegnende del af krav 1 angivne. Til apparatet ifølge opfindelsen skal forgreningerne således hverken ned-30 sænkes i et bassin eller rammes direkte af forstøvet vand.This object is achieved according to the invention in that the apparatus mentioned in the introduction is characterized by the characterizing part of claim 1. Thus, for the apparatus of the invention, the branches must neither be lowered into a basin nor hit directly by atomized water.

Ved apparatet ifølge opfindelsen udsendes stråler, somIn the apparatus of the invention, rays which

- 2 ikke rammer fordamperens forgreninger direkte, men støder mod toppladen og løber derfra over fladen mod forgreningerne, langs hvilken strålerne løber ned og danner terninger . Terningerne fjernes ved reversering af fordam-5 perens arbejdsgang.- 2 does not directly hit the evaporator's branches, but abuts the top plate and runs from there across the surface towards the branches, along which the rays run down and form cubes. The dice are removed by reversing the evaporator operation.

Dette er helt klart et yderst enkelt apparat, hvis drifts princip (anvendelse af stråler i stedet for forstøvning) gør det muligt, at anvende vandforsyningshuller med et tilstrækkeligt stort tværsnit, så at man undgår bloke-10 ring og deraf følgende vedligeholdelsesproblemer.This is clearly an extremely simple device whose operating principle (the use of rays instead of atomization) enables the use of water supply holes of a sufficiently large cross-section to avoid blocking and consequent maintenance problems.

Toppladen kan have en ru underside, så at terningernes vedhæftning til pladen formindskes, hvorved terningerne nemmere kan løsnes.The top plate may have a rough underside, so that the dice attachment to the plate is reduced, making the dice easier to loosen.

I en foretrukken udførelsesform udgør gruppen af vandfor-15 syningsrør en enkelt stiv ramme, som er fastgjort til apparates kabinet på en sådan måde, at rammen kan aftages. Rammen kan således nemt udtages med henblik på periodisk vedligeholdelse.In a preferred embodiment, the group of water supply pipes constitutes a single rigid frame which is attached to the cabinet of the apparatus in such a way that the frame can be removed. Thus, the frame can be easily removed for periodic maintenance.

Opfindelsen forklares nærmere i det følgende under hen-20 visning til tegningen hvor fig.- 1 viser et apparat^ ifølge opfindelsen i plan afbildning fra oven, fig. 2 er et snit af apparatet langs linien II-II i fig.BRIEF DESCRIPTION OF THE DRAWINGS The invention will be explained in more detail below with reference to the drawing, in which: - FIG. 2 is a sectional view of the apparatus along line II-II of FIG.

Third

5 Driftsrummet 2 er inddelt i en øvre del 8 og en nedre del 9 af en vandret topplade 10 med en ru underside f.eks. af gummi eller andet materiale.5 The operating space 2 is divided into an upper part 8 and a lower part 9 of a horizontal top plate 10 with a rough underside e.g. of rubber or other material.

Over toppladen 10 findes en med konsoller 11 fastgjort kølekredsløbsfordamper 12, der i det væsentlige er U-for-10 met i vandret plan som vist i fig. 1. Fra fordamperens 12 to parallelle ben 13 strækker korte forgreninger 14 sig lodret ned, og disse forgreninger passerer gennem toppladen 10 og ender i driftsrummets 2 bund 9. Hver forgrening 14 er hul og rummer en skrå membran 15, som 15 strækker sig fra fordamperbenets 13 top til nær bunden af forgreningen 14, så at der dannes en obligatorisk bane for at få fordampningsgassen gennem forgreningen som vist med pile på tegningen.Above the top plate 10 is a cooling circuit evaporator 12, which is substantially U-shaped in horizontal plane, as shown in FIG. 1. From the two parallel legs 13 of the evaporator 12, short branches 14 extend vertically, and these branches pass through the top plate 10 and end in the bottom 9. of the operating space 2. Each branch 14 is hollow and contains an inclined diaphragm 15 extending from the evaporator leg. 13 top to near the bottom of the branch 14 so that a mandatory path is formed to get the evaporating gas through the branch as shown by arrows in the drawing.

Under toppladen 10 findes en gruppe vandforsyningsrør 20 16, 17, 18, der er indskudt mellem forgreningerne 14 og er indbyrdes forbundet ved hjælp af forbindelsesorganer 26 i en enkelt stiv ramme 19, der er aftageligt fastgjort på kabinettet 1 ved hjælp af sideklips 20. Med rammen 9 i den på tegningen viste driftsstilling er en munding 25 21 i rammen i udløseligt indgreb med en tilsvarende fik- seret munding 22 til modtagelse af vand og levering af dette til rørene 16, 17, 18.Below the top plate 10 is a group of water supply pipes 20 16, 17, 18 which are interposed between the branches 14 and are interconnected by means of connecting means 26 in a single rigid frame 19, which is removably fixed to the housing 1 by side clips 20. With the frame 9 in the operating position shown in the drawing is an orifice 25 21 of the frame in releasable engagement with a correspondingly fixed orifice 22 for receiving water and supplying it to the pipes 16, 17, 18.

Som det tydeligt fremgår af fig. 1 og 3» har midterrøret 16 en række lodrette huller 23 til at levere vandstrå-30 ler opad og mod toppladen 10 mellem forgreningerne, medens de to siderør 17 og 18 har konvergerende skrå huller 24 og 25 med samme funktion.As can be seen clearly in FIG. 1 and 3, the center tube 16 has a series of vertical holes 23 for delivering water jets upwards and toward the top plate 10 between the branches, while the two side tubes 17 and 18 have converging oblique holes 24 and 25 having the same function.

Det på tegningen viste apparat fungerer på følgende måde.The apparatus shown in the drawing functions as follows.

Med rammen 19 i driftsstilling og fordamperen 12 i en , normal arbejdsstilling til frembringelse af kulde, udsendes vandet, som tilføres rørene 16-18, gennem hul-5 lerne 23-25 samt stråler, der er rettet opad og undgår forgreningerne 14 og rammer mod toppladen 10. Her spredes strålerne til siden og løber over pladens 10 ru underside, indtil de møder forgreningerne 14. Vandet falder derpå ned langs forgreningerne 14 ogkofidea-10 serer på grund af kulden og danner derved isterninger 27 omkring disse som vist med stiplede linier i fig. 3.With the frame 19 in the operating position and the evaporator 12 in a normal working position for producing cold, the water supplied to the pipes 16-18 is transmitted through the holes 23-25 and upwardly directed jets and avoids the branches 14 and hits the top plate 10. Here, the rays are spread to the side and run over the rough underside of plate 10 until they meet the branches 14. The water then drops down along the branches 14 and cofideas 10 due to the cold, thereby forming ice cubes 27 around them as shown in dotted lines. FIG. Third

Når terningerne er dannet, selv uden at vandforsyningen samtidigt indstilles, reverseres fordamperens 12 arbejdsgang, idet den frembringer varme, som bevirker, at is-15 terningerne løsnes og falder ned. Terningerne falder ned på den skrå rist 4 og ved åbning af lemmen 6 ind i beholderen 5, medens vandet, der stadig leveres gennem hullerne 23-25, løber ned i beholderen 3 gennem risten 4. Løsningen af terningerne lettes på grund af ruheden på top-20 pladens 10 miderside, hvilket reducerer vedhæftningen mellem pladen og terningerne.When the cubes are formed even without simultaneously adjusting the water supply, the evaporator 12 workflow is reversed, producing heat which causes the ice cubes to loosen and fall. The dice fall on the sloping grate 4 and upon opening of the limb 6 into the container 5, while the water still supplied through the holes 23-25 flows into the container 3 through the grate 4. The solution of the dice is facilitated by the roughness on top. -20 plate 10 center side, reducing adhesion between plate and dice.

Med henblik på periodisk vedligeholdelse af gruppen af tilførselsrør 16-18 er det tilstrækkeligt at åbne klipsene 20 og udtage rammen 19, idet mundingsforskruningen 25 21 føres ud af den fikserede munding 22.For periodic maintenance of the group of supply tubes 16-18, it is sufficient to open the clips 20 and remove the frame 19, the orifice screw 25 21 being removed from the fixed orifice 22.
