Description
Foreliggende ansøkning vedrører en filteranordning for fremstilling av aromauttrekk av kaffe eller te, bestående av en filterbeholder og et filterelement , idet filteranordningens utløp er utformet som en sugehevert og i filterbeholderens indre er anordnet ribber for avstøtting av f ilterelementet . The present application relates to a filter device for the production of aroma extraction from coffee or tea, consisting of a filter container and a filter element, the outlet of the filter device being designed as a suction strainer and in the interior of the filter container ribs are arranged for repelling the filter element.
En filteranordning av denne art er kjent fra US-patent nr. 3.356.010. A filter device of this kind is known from US patent no. 3,356,010.
Den filteranordning som er vist og beskrevet i denne publi-kasjon har en filterbeholder som er utformet som et samle-kammer i det nedre endeområde. På utløpsåpningen til samle-kammeret er det ved hjelp av en tilslutningsdel tilkoblet en sugehevert som består av et rør. The filter device shown and described in this publication has a filter container which is designed as a collecting chamber in the lower end area. A suction strainer consisting of a tube is connected to the outlet opening of the collecting chamber by means of a connecting part.
Sugeheverten befinner seg utenfor filterbeholderen. The suction cup is located outside the filter container.
Fra US-patent nr. 1.922.782 er det kjent en kaffemaskin hvor filtratet strømmer ut fra filterbeholderen ved hjelp av en sugehevert. Sugeheverten utformes der gjennom en U-formet renne i veggen av filterbeholderen, hvorpå et blikk er loddet. Dog filtreres kaffen ikke ved hjelp av et filterelement i kaffemaskinen ifølge US-patent nr. 1.922.782, men ved hjelp av et perforert metallfolie. From US patent no. 1,922,782, a coffee machine is known where the filtrate flows out of the filter container by means of a suction strainer. The suction cup is designed there through a U-shaped channel in the wall of the filter container, on which a sheet is soldered. However, the coffee is not filtered using a filter element in the coffee machine according to US patent no. 1,922,782, but using a perforated metal foil.
Fra tysk Gebrauchsmuster nr. 74 17 342 er det kjent en filteranordning bestående av en filterbeholder og et filterelement hvor støtteribbene danner kanalene for avløpet av filtratet sammen med filterelementet i den nedre del av opp-satsfilteret. From German Gebrauchsmuster No. 74 17 342, a filter device consisting of a filter container and a filter element is known, where the support ribs form the channels for the drain of the filtrate together with the filter element in the lower part of the top filter.
Filteranordningen som er beskrevet i det nevnte Gebrauchsmuster adskiller seg fra vanlige filteranordninger bare ved at det volum som foreligger mellom et filterelement som ligger an mot støtteribbene og filterbeholderens veggparti er betydelig større enn ved filteranordninger av vanlig konstruksjon. Dermed skal tilveiebringes et reservoir for van-net som etterhvert strømmer vekk gjennom en tilsvarende li-ten utløpsåpning som ligger i filterbeholderens bunnområde. The filter device described in the aforementioned Gebrauchsmuster differs from ordinary filter devices only in that the volume that exists between a filter element that rests against the support ribs and the wall portion of the filter container is significantly larger than with filter devices of ordinary construction. Thus, a reservoir must be provided for the water which eventually flows away through a correspondingly small outlet opening located in the bottom area of the filter container.
Oppfinnelsens oppgave ligger i å utforme sugeheverten i en innledningsvis nevnt filteranordning så enkelb som mulig og gjøre den lett rensbar. The task of the invention lies in designing the suction strainer in an initially mentioned filter device as simply as possible and making it easy to clean.
Løsningen av denne oppgave fremgår av hovedkravets karakte-riserende del. The solution to this task appears from the characterizing part of the main requirement.
Den vesentligste fordel ved oppfinnelsen ligger i at en en-da enklere konstruksjon av sugeheverten praktisk talt ikke er tenkelig. Utformingen av de føringsribber som begrenser kanalstykkene, hvilke sammen med det tett tilliggende filterelement danner rørsystemet som virker som sugehevert, betyr i sammenligning med fremstillingen av en filteranordning av vanlig konstruksjon praktisk talt ikke noe mer ar-beide, da det bare dreier seg om å fremstille en tilsvarende form hvori filterbeholderne fremstilles. I den anled-ning er det uten betydning om filterbeholderen fremstilles av plast, slik det idag er vanlig, eller av porselen. Videre er det lett å rense en slik filterbeholder også i det område hvori føringsribbene er formet for å danne kanaler. Ytterligere bygningselementer er ikke nødvendig for dannel-sen av sugeheverten. The most significant advantage of the invention lies in the fact that an even simpler construction of the suction siphon is practically unthinkable. The design of the guide ribs that limit the channel pieces, which together with the close-fitting filter element form the pipe system that acts as a suction strainer, in comparison with the manufacture of a filter device of ordinary construction means practically no more work, as it is only a matter of manufacturing a corresponding form in which the filter containers are manufactured. On that occasion, it is irrelevant whether the filter container is made of plastic, as is common today, or of porcelain. Furthermore, it is easy to clean such a filter container also in the area in which the guide ribs are shaped to form channels. Additional building elements are not necessary for the formation of the suction cup.
Fordelaktige utførelsesformer ved oppfinnelsen er definert gjennom underkravene. Advantageous embodiments of the invention are defined through the subclaims.
Et utførelseseksempel på oppfinnelsen er vist i tegningene og beskrives nærmere i det følgende. Her viser An embodiment of the invention is shown in the drawings and is described in more detail below. Here shows
Fig. 1 et snitt gjennom en filteranordning. Fig. 1 a section through a filter device.
Fig. 2 filterbeholderen sett i retning av pilen II i fig. 1. Fig. 3 et snitt gjennom filterbeholderen langs linjen III - III i fig. 1. Fig. 2 the filter container seen in the direction of arrow II in fig. 1. Fig. 3 a section through the filter container along the line III - III in fig. 1.
I fig. 1 til 3 er vist en f ilterbeholder 1 som eir utført In fig. 1 to 3 shows a filter container 1 that has been made
i ett stykke av plast, i hvilken et filterelement 2 kan innsettes. Filterelementet 2 er i fig. 1 antydet med strek-punkterte linjer. Utløpet 4 fra filterbeholderen 1 dannes av et kanalsystem som består av føringsribber 15 til 17 in one piece of plastic, in which a filter element 2 can be inserted. The filter element 2 is in fig. 1 indicated by dash-dotted lines. The outlet 4 from the filter container 1 is formed by a channel system consisting of guide ribs 15 to 17
som rager innover i filterbeholderen. Ved hjelp av disse føringsribber dannes et fra innsugningsåpningen 6a, som igjen ligger over filterbeholderens 1 laveste del, oppad førende kanalstykke 18 samt et nedad til utløpsåpningen 7a førende ytterligere kanalstykke 19. Føringsribbene 15 til 17 som i form av en runding 20 løper inn i midten av filterbeholderen 1, hvilket meget anskuelig fremgår av fig. 1, er utført litt høyere enn ribbene TO, som tjener til an-legg for filterelementet 2. Følgelig rager føringsribbene 15 til 17 litt mer innover i filterbeholderen 1 enn ribbene which protrudes into the filter container. With the help of these guide ribs, a channel piece 18 leading upwards from the intake opening 6a, which again lies above the lowest part of the filter container 1, as well as a further channel piece 19 leading downwards to the outlet opening 7a is formed. The guide ribs 15 to 17 which in the form of a rounding 20 run into the middle of the filter container 1, which can be clearly seen from fig. 1, is made a little higher than the ribs TO, which serve to support the filter element 2. Consequently, the guide ribs 15 to 17 project a little more inward into the filter container 1 than the ribs
10. Derved oppnås at filterelementet i et hvert tilfelle ligger tett an mot føringsribbene 15 til 17, særlig når fil-treringen innledes, d.v.s. når vann ledes inn i filteranordningen, idet filterelementene da blir mykere enn i tørr tilstand og p.g.a. vanntrykksbelastningen og kaffemelet leg-ger seg praktisk talt avtettende an mot de nevnte førings-ribber 15 til 17. Derved danner kanalstykkene 18 og 19, som avgrenses ved hjelp av føringsribbene 15 til 17, i forbin^ deise med det anliggende filterelement (2) et rørsystem som virker som en sugehevert. Dette utførelseseksemplet ifølge 10. Thereby it is achieved that the filter element in each case lies closely against the guide ribs 15 to 17, especially when the filtering is initiated, i.e. when water is introduced into the filter device, as the filter elements then become softer than in a dry state and due to the water pressure load and the coffee grounds practically seal against the aforementioned guide ribs 15 to 17. Thereby the channel pieces 18 and 19, which are delimited by the guide ribs 15 to 17, in connection with the adjacent filter element (2) form a pipe system that acts as a suction strainer. This embodiment according to
fig. 1 til 3 er særlig fordelaktig av fremstillingstekniske grunner, da denne filterbeholderen, som allerede nevnt, kan fremstilles i et stykke av plast. I praktisk bruk byr denne filterbeholderen ifølge fig. 1 til 3 videre på store forde-ler, da rengjøringen er meget enkel å utføre etter filtre-ringens avslutning. fig. 1 to 3 is particularly advantageous for manufacturing technical reasons, as this filter container, as already mentioned, can be manufactured in one piece of plastic. In practical use, this filter container according to fig. 1 to 3 further on great advantages, as the cleaning is very easy to carry out after the end of the filtration.
