Description
Den foreliggende oppfinnelse vedrører en elektrisk kaffemaskin med en under en varmeplate for en kaffekanne anbrakt plateformet gjennomstrømningsvarmer for traktevannet i et åpent filtersystem, hvor gjennomstrømningsvarmeren omfatter en stort sett horisontal vannkanal som har god varmekontakt med et rørvarmelegeme og har i "det minste et parti med kontinuerlig oppadskrånende, øvre avgrensningsflate. The present invention relates to an electric coffee machine with a flow-through heater placed under a heating plate for a coffee pot for the funnel water in an open filter system, where the flow-through heater comprises a largely horizontal water channel which has good thermal contact with a tube heater and has at least a part with continuous upward sloping, upper boundary surface.
En kaffemaskin av denne type er kjent for eksempel fra A coffee machine of this type is known, for example, from
DAS 2.108.541. Denne maskin omfatter en vannbeholder med en oppstillingsplate som er utstyrt med en elektrisk varmeanordning for en opptaksbeholder ved siden av vannbeholderen og en kanal som er koblet til vannbeholderen for transport av vannet til et filter over opptaksbeholderen, idet en del av kanalen er dannet av et vannkanner som løper under oppstillingsplaten. Vannkammeret er ved oversiden utstyrt med et damprom som er avgrenset av skillevegger som løper på tvers av vannets trans-portretning. Avstanden mellom den nedre vegg og den øvre vegg i vannkammeret er derved større enn avstanden mellom sideveggene. Vannkammerets tverrsnitt er imidlertid konstant. DAS 2,108,541. This machine comprises a water container with a stand plate which is equipped with an electric heating device for a receiving container next to the water container and a channel connected to the water container for transporting the water to a filter above the receiving container, part of the channel being formed by a water jug which runs under the mounting plate. The water chamber is equipped on the upper side with a steam room which is delimited by partitions that run across the trans-portation of the water. The distance between the lower wall and the upper wall in the water chamber is thereby greater than the distance between the side walls. However, the cross-section of the water chamber is constant.
Forsøk viser at ved en slik utforming av kaffemaskinen strømmer vannet som en flom ut av vannoverløpet, noe som kan føre til en mer eller mindre sterk støyutvikiing og at vannet spruter ut av vannoverløpet. Tidsrommet mellom utstrømmingen av vannet fra vannbeholderen og utkoblingen av apparatet eller tørrkokingen av gjennomstrømningsvarmeren er også relativt stor hos de kjente apparater. Dette skyldes vannkammerets kapasitet, idet mye vann behøver mye tid for fordampingen. Tests show that with such a design of the coffee machine, the water flows like a flood out of the water overflow, which can lead to a more or less strong noise development and the water splashing out of the water overflow. The time period between the outflow of the water from the water container and the disconnection of the device or the dry boiling of the through-flow heater is also relatively long in the known devices. This is due to the capacity of the water chamber, as a lot of water needs a lot of time for evaporation.
Dersom vannkammeret gjøres mindre må man imidlertid regne med hurtigere kalkdannelse. However, if the water chamber is made smaller, faster scale formation must be expected.
Formålet med oppfinnelsen er å forbedre vannføringen i The purpose of the invention is to improve the flow of water in
en elektrisk kaffemaskin med åpent filtersystem på en slik måte an electric coffee machine with an open filter system in such a way
at støy unngås og en utsprøyting av vannet fra vannoverløpet hindres. Denne oppgave blir ifølge oppfinnelsen løst ved at vannkanalen fra vanninnløp til vannutløp har en horisontal nedre avgrensningsflate og en kontinuerlig oppadskrånende Øvre avgrensningsflate, slik at vannkanalens tverrsnitt stadig øker i vannets strømningsretning. that noise is avoided and a spraying of the water from the water overflow is prevented. According to the invention, this task is solved by the water channel from water inlet to water outlet having a horizontal lower delimiting surface and a continuously upwardly sloping Upper delimiting surface, so that the water channel's cross-section constantly increases in the direction of the water's flow.
lied denne løsning oppnås det en jevn vannstrøm og at det varme vann strømmer jevnt ut. Likeledes kan dampblærer lett unnslippe til utløpet og derved til stigrøret. with this solution, a steady flow of water is achieved and the hot water flows out evenly. Likewise, steam bubbles can easily escape to the outlet and thereby to the riser.
En annen fordel med løsningen ifølge oppfinnelsen oppnås véd at vanninntaket, som i tverrsnitt er vesentlig mindre enn vannutløpet,oppviser en strømningsmotstand overfor vannutløpet Another advantage of the solution according to the invention is achieved by the fact that the water inlet, which in cross-section is significantly smaller than the water outlet, exhibits a flow resistance to the water outlet
-i motstrøm, slik at det unngås en sterkere tilbakekoking. - in countercurrent, so that a stronger back-boiling is avoided.
Et utførelseseksempel av kaffemaskinen ifølge oppfinnelsen vil bli beskrevet i.det Ætterfølgende under henvisning til de medfølgende tegninger, hvori: Fig. 1 viser i et langsgående snitt plasseringen av den plateformete gjennomstrømningsvarmer under en oppstillingsplate for en kaffekanne. Fig. 2 viser et grunnriss av den plateformete gjennom-strømningsvarmer . An embodiment of the coffee machine according to the invention will be described in the following with reference to the accompanying drawings, in which: Fig. 1 shows in a longitudinal section the location of the plate-shaped flow heater under a stand plate for a coffee pot. Fig. 2 shows a plan view of the plate-shaped through-flow heater.
Fig. 3 viser et snitt etter linjen A-B i fig. 2. Fig. 3 shows a section along the line A-B in fig. 2.
En kaffemaskin med en oppstillings- eller varmeplate a for en kaffekanne b er utstyrt med en under oppstillings- eller varmeplaten anbrakt plateformet gjennomstrømningsvarmer c for traktevannet. Gjennomstrømningsvarmeren omfatter en horisontal vannkanal d, langs hvilken det i god varmekontakt løper et rørvarmelegeme e. Ifølge oppfinnelsen skrår vannkanalens d øvre avgrensningsflate f kontinuerlig oppad fra et vanninntak A coffee machine with a stand-up or heating plate a for a coffee pot b is equipped with a flow-through heater c for the tap water placed below the stand-up or heating plate. The through-flow heater comprises a horizontal water channel d, along which a tube heating element e runs in good thermal contact. According to the invention, the upper delimiting surface f of the water channel d slopes continuously upwards from a water intake

Vannkanalens utløp d-, har et vesentlig større tverrsnitt enn vanninntaket d^. Et deksel g danner vannkanalens nedre avgrensningsflate og lukker kanalen. The water channel is also designed asymmetrically in that the mutual distance between its side walls f2, f^ continuously increases in the direction of flow for the hot water. The water channel's outlet d-, has a significantly larger cross-section than the water intake d^. A cover g forms the lower boundary surface of the water channel and closes the channel.
