Description
Brüharmatur mit Brühgloeke für Gegenstand der Erfindung ist eine Brüh armatur mit Brühglocke für Kaffeemaschi nen, welche unter Dampfdruck arbeiten, zum Brühen von Kaffee in Einzeltassen und Portionen.
Beiliegende Zeichnung stellt ein Aus führungsbeispiel des Erfindungsgegenstan des dar.
Fig. 1 stellt den Vertikalschnitt im Auf riss, Fig. 2 die Ansicht der Bohrungen (Stopf büchse herausgenommen), und Fig. 3 die Ansicht im Aufriss dar.
Das Gehäuse 1 hat drei Bohrungen 2, 3 und 4. 2 ist der Wasserkanal, 3 der Dampf kanal, und 4 und 10 bilden die Abführ leitung des Überdruckes nach dem Brühvor gang. Die Blindschraube 6 versperrt den Kanal 4 gegen den Kessel 5. Die Bohrung 9 mündet in den Dampfkessel 3 und hat den Zweck, dass auch, je nach der Verwendung bezw. Anordnung der Brüharmatur, der Dampf von aussen angeschlossen werden kann; im letzteren Fall wird das freie Ende der Bohrung 3 mittelst Schraube verschlos sen. Am Ausführungsbeispiel ist die Boh rung 3 frei und Bohrung 9 aussen ver schlossen (Fig.3).
Der Kolben 7 ist in bekannter Weise mit dem Hebel 11 verbunden. 8 ist eine Dich tungsscheibe mit einer Nut 12, die je nach der Hebelstellung den entsprechenden Kanal frei gibt. Die Stopfbüchse ist so angeordnet, dass durch Lösen der Schraube 13 die ganze Stopfbüchsenpartie bequem und rasch zum Zwecke des Einschleifens oder zum Reinigen ,der Kanäle 2, 3 und 4 herausgenommen Wer den kann.
Am Auge 14 ist die Brühglocke 15, gegen Verdrehung gesichert, mittelst Sahraub- stutzen 16 angeschraubt und abgedichtet. Der .Schraubstutzen 16 hat kleine Bohrun gen 17, welche das Wasser auf das Sieb 18 verteilen, letzteres wird durch den Schrau benkopf 19 gehalten.
In der tief eingedreh ten Ringnut sitzt der Gummiring 20 derart, ,dass der Siebhalter 21 noch in die Ringnut satt eingreift, der Gummiring nicht aus- weichen kann und infolgedessen auch nicht mit dem Kaffee in Berührung kommt.
Die auf dem Markt befindlichen Brüh armaturen dieser Art haben den Nachteil, dass der Kaffee mit dem den Siebhalter an der Glocke abdichtenden Gummiring in Be rührung kommt und den Geschmack des fer tigen Getränkes nachteilig beeinflusst.
Die Blühglocke 15 (Fig. 3) hat zwei ein ander diametral gegenüberliegende Doppel- Bajonettverschlussnuten 22, deren freie Schenkel <B>je</B> eine schiefe Ebene 22a bilden, auf welcher die am Siebhalter 21 einander gegenüberliegenden Rollen 23, welche um Zapfen 24 drehbar sind, beim Drehen am Griff 25 aufliegen und den Siebhalter ab dichten.
Durch die doppelseitige Ausbildung der Bajonettnuten 22 kann die Blüharmatur so wohl durch Rechts-, wie durch Linksdrehen des Siebhalters abgedichtet werden. Der An schlag<B>26</B> dient zum leichteren Einführen des Siebhalters 21 in die Glocke 15. Das Filtersieb 27 ist im Halter 21 eingesprengt. Die Bedienung der Blüharmatur ist sehr einfach und kann mit einer Hand geschehen. Der Blühvorgang ist bekannt und stellt niehts Neues dar.
Brewing fitting with brewing bell for the subject of the invention is a brewing fitting with brewing bell for Kaffeemaschi NEN, which work under steam pressure, for brewing coffee in individual cups and portions.
The accompanying drawing shows an exemplary embodiment of the subject matter of the invention.
Fig. 1 shows the vertical section in elevation, Fig. 2 shows the view of the holes (stuffing box removed), and Fig. 3 shows the view in elevation.
The housing 1 has three bores 2, 3 and 4. 2 is the water channel, 3 is the steam channel, and 4 and 10 form the discharge line of the excess pressure after the Brühvor gang. The blind screw 6 blocks the channel 4 against the boiler 5. The bore 9 opens into the steam boiler 3 and has the purpose that, depending on the use or respectively. Arrangement of the brewing armature, the steam can be connected from the outside; in the latter case the free end of the bore 3 is closed by means of a screw. In the exemplary embodiment, the Boh tion 3 is free and bore 9 outside ver closed (Fig.3).
The piston 7 is connected to the lever 11 in a known manner. 8 is a log processing disk with a groove 12, which releases the corresponding channel depending on the lever position. The stuffing box is arranged so that by loosening the screw 13 the whole stuffing box part can be removed easily and quickly for the purpose of grinding in or for cleaning, the channels 2, 3 and 4 who can.
The brewing bell 15, secured against rotation, is screwed to the eye 14 by means of a Sahraub connector 16 and sealed. The .Schraubstutzen 16 has small holes 17, which distribute the water on the sieve 18, the latter is held by the screw head 19.
The rubber ring 20 sits in the deeply screwed-in annular groove in such a way that the strainer holder 21 still engages fully in the annular groove, the rubber ring cannot escape and consequently does not come into contact with the coffee.
The brewing fittings of this type on the market have the disadvantage that the coffee comes into contact with the rubber ring that seals the strainer holder on the bell and adversely affects the taste of the finished drink.
The flower bell 15 (FIG. 3) has two diametrically opposite double bayonet locking grooves 22, the free legs of which each form an inclined plane 22a on which the rollers 23 on the screen holder 21 opposite one another, which around pegs 24 are rotatable, rest on the handle 25 when turning and seal the screen holder.
Due to the double-sided design of the bayonet grooves 22, the flowering valve can be sealed by turning the screen holder to the right or to the left. The stop <B> 26 </B> serves to facilitate the introduction of the screen holder 21 into the bell 15. The filter screen 27 is snapped into the holder 21. The flowering armature is very easy to operate and can be done with one hand. The flowering process is known and is nothing new.
