Description
DK 152077BDK 152077B
Opfindelsen angår et apparat til øjeblikkelig levering af kogende vand til brug ved fremstilling af mad og drikkevarer, og bestående af en varmeisoleret beholder, som er i stand til at modstå et tryk på mindst 6 atm., hvilken beholder er forsynet med et med en 5 tappeventil forsynet vandudløb og ved sin bund er forsynet med et indløb, som er beregnet til at kunne sættes i forbindelse med vandforsyningssystemet, og hvor beholderen er arbejdsmæssigt forbundet med opvarmningsorganer, der er i stand til at opvarme beholderens indhold til en temperatur, der er større end 100°C, hvilke opvarmnings-10 organer er styret af en termostat, der er i stand til at regulere vandets temperatur til et niveau mellem 100°C og 120°C.BACKGROUND OF THE INVENTION 1. Field of the Invention The invention relates to an apparatus for the immediate delivery of boiling water for use in the manufacture of food and beverages, and comprising a heat insulated container capable of withstanding a pressure of at least 6 atm. tap valve provided with water outlet and at its bottom is provided with an inlet which is intended to be connected to the water supply system and wherein the container is operatively connected to heating means capable of heating the contents of the container to a temperature higher than 100 ° C, which heating means is controlled by a thermostat capable of controlling the temperature of the water to a level between 100 ° C and 120 ° C.
Fra de engelske patentbeskrivelser nr. 706.866 og 1.106.031 kendes apparater til levering af kogende vand. Disse apparater har en beholder, der ved sin bund har et indløb til indførsel af koldt vand 15 fra vandforsyningsnettet. Oven over indløbet findes et elektrisk varmelegeme til opvarmning af vandet i beholderen. Opvarmet vand kan aftappes gennem et udløb med en tappehane nær beholderens bund.From British Patent Specifications Nos. 706,866 and 1,106,031, boiling water dispensers are known. These appliances have a container which at its bottom has an inlet for introducing cold water 15 from the water supply network. Above the inlet is an electric heater for heating the water in the container. Heated water can be drained through an outlet with a tapping tap near the bottom of the container.
Ved lukket tappehane kan beholderens indhold af vand på grund af den volumenforøgelse, som vandet får ved opvarmningen og det der-20 af følgende højere tryk i beholderen, uden at koge opvarmes til en temperatur, der er noget højere end vandets kogetemperatur ved atmosfæretrykket. For at forhindre at opvarmet vand på grund af overtrykket i beholderen skal blive trykket tilbage i vandforsyningsnettet, har indløbet fra vandforsyningsnettet til beholderen en sådan 25 størrelse, at det minimerer det tilbagegående tryk ind i vandforsyningsnettet gennem indløbet. Derved skal det desuden sikres, at det fra koldtvandsnettet indstrømmende vand ved aftapning af varmt vand fra beholderen strømmer ind med en tilstrækkelig lav hastighed til at forhindre, at det afkøler indholdet af beholderen så stærkt, at tempe-30 raturen af det vand, der aftappes, sænkes til under den ønskede aftapningstemperatur. Når der er behov for varmt vand, aftappes dette sædvanligvis med en større hastighed end den forholdsvis lille hastighed, hvormed vand fra vandforsyningsnettet kan strømme gennem det af de forannævnte grunde reducerede tværsnit af indløbet og ind i 35 beholderen. På grund af denne drøvlede tilstrømning af vand fra vandforsyningsnettet fås der ved aftapning af vand fra beholderen et trykfald i dennes indre, hvorved vandet i beholderen begynder at koge, når trykket i beholderen underskrider det damptryk, som svarer til 2With closed tap tap, the container's content of water due to the volume increase the water receives upon heating and the resulting higher pressure in the container, without boiling, is heated to a temperature somewhat higher than the boiling temperature of the water at atmospheric pressure. To prevent heated water from being pushed back into the water supply network due to overpressure in the vessel, the inlet from the water supply network to the vessel has a size such that it minimizes the back pressure into the water supply network through the inlet. In addition, it must be ensured that the water flowing from the cold water network, when draining hot water from the container, flows in at a sufficiently low rate to prevent it from cooling the contents of the container so strongly that the temperature of the water being drained , is lowered to below the desired tapping temperature. When hot water is needed, this is usually discharged at a greater rate than the relatively small rate at which water from the water supply network can flow through the reduced cross-section of the inlet for the aforementioned reasons and into the container. Due to this swirling inflow of water from the water supply network, when the water is drained from the vessel, a pressure drop in its interior is obtained, whereby the water in the vessel starts to boil when the pressure in the vessel falls below the vapor pressure corresponding to 2.

den temperatur, hvortil vandet i beholderen er opvarmet. Da vandet er opvarmet til en temperatur, der ligger over 100°C, er damptrykket større end 1 atm. og tjener således som drivtryk for vandet, der skal aftappes. Ved disse kendte apparater er det en ulempe, at både ind-5 løbet og udløbet er anbragt nær bunden, idet koldt vand, der ved aftapning af varmt vand indtræder fra vandforsyningsnettet gennem beholderens indløb, vil søge den korteste vej hen mod aftapningsstedet, d.v.s. udløbet. Med mindre der træffes særlige foranstaltninger, f. eks. i form af komplicerede ledeplader, vil der fås en blanding af 10 varmt og koldt vand ved aftapningsstedet med en deraf følgende uønsket sænkning af vandets aftapningstemperatur. En anden ulempe er, at der, når der opstår kogning i beholderen på grund af det ved aftapning af varmt vand forårsagede trykfald i beholderen, frigøres luft, som altid er indholdt i ledningsvand, og denne luft vil samle sig 15 i toppen af beholderen sammen med den ved kogningen udviklede damp. Der skal derfor sørges for en udblæsning af luften, idet beholderkapaciteten ellers vil blive formindsket på grund af luftakkumulation i beholderens top. Da varmelegemet endvidere såvidt muligt konstant skal være helt dækket af vand, kan selve anbringelsen af var-20 melegemet være forbundet med problemer, idet det skal anbringes neden under beholderens lavest mulige vandstand, d.v.s. neden under den forholdsvis nær beholderens bund anbragte udløbsåbning. Ganske vist viser den engelske patentbeskrivelse nr. 1.106.031 en udførelsesform (fig. 7), ved hvilken der anvendes et varmelegeme, der strækker 25 sig et betydeligt stykke opad gennem beholderen. Varmelegemet er her anbragt i en indvendig, for oven åben, men for neden lukket beholder, i hvis nederste del en ledning fra vandforsyningsnettet indmunder. Denne beholders øverste åbne ende ligger nær toppen af selve vandbeholderen, der ved sin bund er forsynet med aftapnings-30 stedet. Indstrømmende vand fra vandforsyningsnettet vil først fylde den indvendige beholder, indtil vandet løber ud over den øverste kant af denne og fylder resten af vandbeholderen. Dette betyder, at den indvendige beholder, selv når den uden om denne beliggende del af vandbeholderen er tømt helt ned til aftapningsstedet, stadig vil in-35 deholde vand, der når op over varmelegemet. Denne udformning med en indvendig beholder komplicerer imidlertid fremstillingen af selve vandbeholderen og kan desuden virke hæmmende for varmelegemets afgivelse af varme til den mængde vand, der befinder sig mellem denthe temperature to which the water in the container is heated. As the water is heated to a temperature above 100 ° C, the vapor pressure is greater than 1 atm. and thus serves as the driving pressure for the water to be drained. With these known devices, it is a disadvantage that both the inlet and outlet are located near the bottom, as cold water which, when draining hot water, enters from the water supply network through the inlet of the container, will seek the shortest path towards the bottling point, i.e.. expired. Unless special measures are taken, for example in the form of complicated baffles, a mixture of 10 hot and cold water will be obtained at the bottling site with a consequent undesirable lowering of the bottling temperature of the water. Another disadvantage is that when boiling occurs in the container due to the pressure drop caused by hot water in the container, air which is always contained in tap water is released and this air will collect at the top of the container. with the steam developed during boiling. Therefore, the air must be blown out, otherwise the capacity of the container will be reduced due to air accumulation at the top of the container. Furthermore, since the heater must, as far as possible, be constantly completely covered by water, the actual placement of the heater body may be associated with problems, being placed below the lowest possible water level of the container, i.e. below the outlet opening located relatively near the bottom of the container. Admittedly, British Patent Specification No. 1,106,031 shows an embodiment (Fig. 7) using a heater extending a considerable distance upwardly through the container. The heater is located here in an interior, open above, but below closed container, in the lower part of which a line from the water supply network opens. The upper open end of this container is located near the top of the water container itself, which at its bottom is provided with the draining spot. Flowing water from the water supply network will first fill the inner container until the water runs over the upper edge thereof and fills the rest of the water tank. This means that, even when emptied around this portion of the water tank all the way down to the point of drainage, the inner container will still contain water reaching over the heater. However, this design with an inner container complicates the preparation of the water tank itself and can also inhibit the delivery of heat to the amount of water between the heater

3 indvendige beholders yderside og selve vandbeholderens inderside. En yderligere ulempe ved de kendte apparater viser sig ved indledningen af aftapningen af varmt vand. Ved fyldt beholder med opvarmet indhold af vand står beholderen mindst under det i vandforsyningsnet-5 tet herskende tryk, idet dette forplanter sig fra tilførselsledningen til beholderens indre. Så snart tapningen indledes, falder trykket i beholderen på grund af indløbets indsnævrede tværsnit til det damptryk, der svarer til den i beholderen herskende temperatur og betragtet som drivtryk over tappeventilen kun er en lille brøkdel af begyn-10 delsesdrivtrykket. Dette vil medføre, at der ved åbning af tappeventilen først fås en momentan kraftig udstødning af varmt vand efterfulgt af en "doven" strøm.3 outside of the inner container and the inside of the water container itself. A further disadvantage of the known apparatus is apparent at the onset of hot water drainage. For filled containers with heated contents of water, the container is at least under the pressure prevailing in the water supply network as it propagates from the supply line to the interior of the container. As soon as the tapping is started, the pressure in the container, due to the narrow cross section of the inlet, drops to the vapor pressure corresponding to the temperature prevailing in the container and considered as the driving pressure above the tapping valve is only a small fraction of the initial drive pressure. This will result in the instantaneous strong exhaust of hot water being followed by a "lazy" stream.
Formalet med opfindelsen er at tilvejebringe et apparat til øjeblikkelig afgivelse af kogende vand, ved hvilket samtlige af de nævn-15 te ulemper er elimineret.The object of the invention is to provide an apparatus for immediate delivery of boiling water, by which all of the aforementioned disadvantages are eliminated.
Denne opgave løses ifølge opfindelsen ved, at indløbet er udformet til tilnærmelsesvis uindskrænket forbindelse med vandforsyningssystemet, at udløbet er anbragt ved beholderens top, og at tappeventilen er indrettet til rolig afgivelse af det aftappede vand. Da indløbet 20 ved beholderens bund er indrettet til frit indløb af vand fra vandforsyningsnettet, og da den hastighed, hvormed varmt vand aftappes fra beholderen, således ikke overskrider den hastighed, hvormed nyt vand indtræder i beholderen, er det selve vandforsyningsnettets ledningstryk og ikke et damptryk, der tjener til uddrivning af vandet 25 ved aftapning. Dette betyder, at der fra apparatet ifølge den foreliggende opfindelse aftappes på samme måde som der tappes fra en almindelig til vandforsyningsnettet sluttet ventil. Dette medfører, at det kogende vand aftappes ved et stort set konstant drivtryk, nemlig trykket i vandforsyningsnettet. Der dannes ingen damplomme med et 30 indhold af opløste luftarter (luft og carbondioxid) i toppen af beholderen. Der skal således ikke sørges for særlige organer til afblæsning af akkumuleret luft i toppen af beholderen. Afblæsning af de opløste luftarter sker momentant ved aftapningen.This task is solved according to the invention in that the inlet is designed for an almost unrestricted connection with the water supply system, that the outlet is arranged at the top of the container and that the tapping valve is arranged for calm delivery of the drained water. Since the inlet 20 at the bottom of the container is arranged for free flow of water from the water supply network, and since the speed at which hot water is drained from the container does not exceed the speed at which new water enters the container, it is the conduction pressure of the water supply network itself and not a vapor pressure. which serves to expel the water 25 upon tapping. This means that the apparatus according to the present invention is drained in the same way as is drawn from a regular valve connected to the water supply network. This causes the boiling water to be drained at a substantially constant driving pressure, namely the pressure in the water supply network. No vapor plume with a content of dissolved gases (air and carbon dioxide) is formed at the top of the vessel. Thus, no special means is provided for blowing accumulated air at the top of the container. The dissolved gases are blown off instantaneously at the bottling.
For at forhindre at det indstrømmende kolde vand blander 35 sig med det i beholderen værende varme vand, kan der hensigtsmæssigt ud for indløbet være anbragt en fordelerplade. Da beholderens indløb og udløb befinder sig ved hver sin ende af beholderen, kan denne fordelerplade være af ganske enkel udformning. Da det ind-In order to prevent the flowing cold water from mixing with the hot water present in the container, a distributor plate may conveniently be arranged next to the inlet. Since the inlet and outlet of the container are located at each end of the container, this distributor plate can be of a simple design. As it

4 strømmende kolde vand vil samle sig ved bunden, er det fordelagtigt at anbringe varmeelementet ved denne.4 flowing cold water will collect at the bottom, it is advantageous to place the heating element thereon.
Forsøg har vist, at der ved apparatet ifølge opfindelsen ikke forekommer nogen særlig høj sammenblandingsgrad mellem det indstrøm-5 mende vand og det varme indhold i beholderen, hvilket skyldes, at trykfaldet under aftapning primært finder sted over aftapningsventi-len. Forsøg med apparatet ifølge den foreliggende opfindelse har siledes vist, at man fra en beholder med en vandkapacitet pi 3 I kan aftappe 2,5 I kogende vand selv med et varmeelement med si lille en ef-10 fekt som 750 Watt. Til grund for opfindelsen ligger den erkendelse, at sammenblanding af koldt og varmt vand ikke er særlig stor, nir vandet er opvarmet til den meget høje temperatur, idet temperaturforskellen mellem det opvarmede vandindhold i beholderen og det tilstrømmende vand (f.eks. 110°C og 20°C) er si stor, at der fis en væsent-15 lig vægtfyldeforskel, som i høj grad modvirker den cirkulation og dermed sammenblanding, som ellers kunne forventes.Tests have shown that in the apparatus according to the invention there is no particularly high degree of mixing between the flowing water and the hot content of the container, which is due to the fact that the pressure drop during draining takes place primarily over the drain valve. Experiments with the apparatus of the present invention have thus shown that from a container with a water capacity of 3 liters, 2.5 liters of boiling water can be drained even with a heating element having as little an effect as 750 Watt. The invention is based on the recognition that the mixing of cold and hot water is not very great when the water is heated to the very high temperature, since the temperature difference between the heated water content of the container and the flowing water (e.g. 110 ° C and 20 ° C) is so large that there is a significant difference in density which greatly offsets the circulation and thus mixing that might otherwise be expected.
I det følgende forklares opfindelsen nærmere under henvisning til tegningen, der viser et lodret snit gennem en udførelsesform for et apparat ifølge opfindelsen.The invention will now be explained in more detail with reference to the drawing, which shows a vertical section through an embodiment of an apparatus according to the invention.
20 Tegningen viser et apparat 1 ifølge opfindelsen, som er mon teret under en vask 2. Apparatet 1 har en beholder 5 med et i beholderbunden anbragt indløb i form af en sædvanlig kontraventil 4, der er direkte forbundet med et vandforsyningsnet 3. Beholderen 5 er ved sin top over et rør 6 forbundet med en udløbs- eller aftapning s ventil 25 7. Beholderen og udløbsdelene 6 og 7 er omgivet af et isolerende ma teriale 8. Beholderen 5 indeholder desuden et elektrisk varmelegeme 9 med tilslutninger 10. En termostat 11, der styrer en kontakt 12, kan over en varmeleder 13 være forbundet med varmelegemet, siledes at opvarmningen kan afbrydes i tilfælde af, at vandbeholderen kun er del-30 vis fyldt. Nær beholderens bund er der overfor vandindløbet anbragt en fordelerplade 14 for at undgå blanding af det i beholderen værende varme vand med indstrømmende koldt vand. Endvidere indeholder apparatet en afbryder 15 til afbrydelse af opvarmningen, dersom termostaten skulle svigte. Apparatet har desuden en gevindstuds 16 til 35 tilslutning af forskelligt tilbehør.The drawing shows an apparatus 1 according to the invention mounted under a sink 2. The apparatus 1 has a container 5 with an inlet placed in the container bottom in the form of a conventional check valve 4 directly connected to a water supply network 3. The container 5 is at its top over a pipe 6 connected to an outlet or drain valve 25 7. The container and outlet portions 6 and 7 are surrounded by an insulating material 8. The container 5 also contains an electric heater 9 with connections 10. A thermostat 11, controlling a contact 12, over a heater 13 may be connected to the heater, so that the heating can be interrupted in the event that the water tank is only partially filled. Near the bottom of the container, a distributor plate 14 is arranged opposite the water inlet to avoid mixing the hot water present in the container with cold running water. In addition, the apparatus includes a switch 15 for switching off the heating should the thermostat fail. The apparatus additionally has a threaded connector 16 to 35 connecting various accessories.
Pi tegningen er apparatet vist med en elektrisk opvarmning. Naturligvis kan der også anvendes gasopvarmning ved apparatet ifølge opfindelsen. I så tilfælde kan vågeflammen anvendes til at kompensere for størstedelen af varmetabene.In the drawing, the apparatus is shown with an electric heating. Of course, gas heating can also be used in the apparatus of the invention. In this case, the dimmer flame can be used to compensate for the majority of heat losses.
