Description

Anordning for å hindre overkokning av væsker, spesielt melk. Device to prevent liquids, especially milk, from boiling over.

Oppfinnelsen angår en anordning for å hindre overkokning av væsker, spesielt The invention relates to a device for preventing overboiling of liquids, in particular

melk, bestående av en i kokekaret innsatt tallerken med et antall huller og forsynt med en midtre hette som også er forsynt med gj ennomløpshuller for overkoket, idet det under tallerkenen er anbragt en annen tallerken med en midtre åpning. Anordningen etter oppfinnelsen karakteriseres ved at den undre tallerken er anordnet hev- og senkbar under den øvre tallerken. milk, consisting of a plate inserted in the cooking vessel with a number of holes and provided with a central cap which is also provided with through-flow holes for the overboiled, as another plate with a central opening is placed under the plate. The device according to the invention is characterized by the fact that the lower plate is arranged so that it can be raised and lowered under the upper plate.

Hensikten hermed er følgende: Under The purpose hereof is the following: Below

kokningen vil damptrykket løfte den undre tallerken opp under den øvre, gjennomhullede tallerken og derved tette igjen dennes hull, slik at det gjennom hettens åpninger utstrømmende overkok blir liggende på den øvre tallerken og avkjøles inntil tyngden blir så stor at den undre tallerken presses nedad og væsken kan strømme tilbake i karet, gjennom hullene i den øvre tallerken. during boiling, the steam pressure will lift the lower plate up under the upper, perforated plate and thereby seal its holes, so that the boiling water flowing out through the hood's openings remains on the upper plate and cools until the weight becomes so great that the lower plate is pressed downwards and the liquid can flow back into the tub, through the holes in the upper plate.

På tegningen er vist et utførelseseks-empel av anordningen, idet fig. 1 viser et vertikalsnitt gjennom et kokekar med over-kokningsinnretningen innmontert. Fig. 2 viser denne innretning sett fra undersiden. The drawing shows an exemplary embodiment of the device, as fig. 1 shows a vertical section through a cooking vessel with the over-boiling device installed. Fig. 2 shows this device seen from the underside.

Kokekaret 1 er i eksempel i passe av-stand fra bunnen forsynt med innbøyd, om-løpende sete 2 som den øvre tallerken 3 hviler på, med en ytre, nedadbøyd flensdel. Tallerkenen 3 er forsynt med et antall, i en sirkulær bane anbrakte huller 8, gjennom hvilke overkoket renner tilbake i karet 1. Tallerkenen 3 er i midten forsynt med en sylindrisk, oppadrettet hette 4, forsynt nær toppen med et antall hull 5. Under tallerkenen 3 er anbragt en annen tallerken 6 med et større, midtre hull, omgitt av en nedadrettet flens 7. Normalt hviler denne tallerken på bæreknaster 9 på tallerkenens 3 kantflens. Tallerkenen 6 er ved periferien forsynt med sektorformede utskjæringer 10, The cooking vessel 1 is, for example, at a suitable distance from the bottom, provided with a bent, revolving seat 2 on which the upper plate 3 rests, with an outer, downwardly bent flange part. The plate 3 is provided with a number of holes 8 arranged in a circular path, through which the overboiled flows back into the vessel 1. The plate 3 is provided in the middle with a cylindrical, upwardly directed cap 4, provided near the top with a number of holes 5. Below the plate 3, another plate 6 is placed with a larger, central hole, surrounded by a downward-facing flange 7. Normally, this plate rests on support lugs 9 on the edge flange of the plate 3. The plate 6 is provided at the periphery with sector-shaped cutouts 10,

svarende til knastene 9, slik at tallerkenen corresponding to the lugs 9, so that the plate

6 kan føres forbi knastene 9. 6 can be passed past the lugs 9.

Etter oppfinnelsen er nå den undre tallerken 6 anordnet fritt hev- og senkbar i . forhold til den øvre tallerken 3. Når derfor væsken koker og danner damp, vil den undre tallerken 6 presses tettende opp under den gjennomhullede, øvre tallerken og tette dennes huller 8. Overkoket som strømmer opp gjennom hetten 4 og ut gjennom dennes huller 5, blir derfor liggende til avkjø-ling på tallerkenen 3, uten å kunne renne tilbake til karet 1, før vekten av overkoket blir så stor at tallerkenen 6 presses nedad. Væsken får derfor bedre tid enn normalt til å avkjøles før den renner tilbake i kokekaret 1. Forsøk viser at ved kokning av melk ved svak varme, vil kokningen i karet periodevis stanse, for så i neste øyeblikk å ta til igjen. Ved fosskokning av melk, vil anordningen effektivt hindre overkokning av kartoppen. Har kokekaret intet sete 2 for tallerken 3 kan denne være forsynt med ben, som når ned til karbunnen. Tallerken 6 kunne også holdes oppe av setet 2 eller på annen måte. Following the invention, the lower plate 6 is arranged to be freely raised and lowered in . relation to the upper plate 3. When the liquid therefore boils and forms steam, the lower plate 6 will be pressed tightly up under the perforated upper plate and seal its holes 8. The boiled water that flows up through the cap 4 and out through its holes 5 becomes therefore lying to cool on the plate 3, without being able to flow back to the vessel 1, before the weight of the overboiled becomes so great that the plate 6 is pressed downwards. The liquid therefore has more time than normal to cool down before it flows back into the cooking vessel 1. Experiments show that when milk is boiled at low heat, the boiling in the vessel will periodically stop, only to resume at the next moment. When boiling milk in a waterfall, the device will effectively prevent the kettle from boiling over. If the cooking vessel has no seat 2 for plate 3, this can be provided with legs, which reach down to the bottom of the vessel. The plate 6 could also be held up by the seat 2 or in some other way.

Claims

1. Device to prevent the overboiling of liquids, especially milk, consisting of a plate placed in the cooker, with a number of holes, and provided with a central, upright and perforated cap, and where under said plate is placed a another plate with a central, larger opening, characterized in that the lower plate (6) is arranged to be freely raised and lowered in relation to the upper perforated plate (3), so that it can be pressed tightly by the steam pressure in the vessel (1) up under the upper plate (3) and prevents it re-

nom the hood (4, 5) the flowing overboil to flow back to the vessel, before the weight of the overboil becomes so great that the lower plate (6) is pressed downwards, thereby achieving better cooling of the overboil before it flows back into the vessel (1).

2. Device according to claim 1, characterized in that the upper plate (3) is provided with legs extending to the vessel bottom.

3. Device according to claim 1 or 2, characterized in that the upper plate (3) is provided with a downward-facing edge flange with support lugs (9) for the lower plate (6).
