Die Erfindung betrifft einen kompakten Durchlauferhitzer mit Pumpsystem für die Zubereitung von heißem Wasser, insbesondere für Kaffeemaschinen und Teemaschinen mit Thermokanne.The invention relates to a compact instantaneous water heater with a pump system for the preparation of hot water, in particular for coffee machines and tea machines with a thermos jug.
Kaffeemaschinen üblicher Bauart bestehen im wesentlichen aus der Kaffekanne, der Filtereinheit und dem Gehäuse, in dem von unten der Durchlauferhitzer, bestehend aus dem elektrischen Heizrohr mit Rückschlagventil, Schlauchanschlüssen, Reglereinheit mit Thermosicherung, elektrische Anschlußleitungen und der Schalter mit Kontrolleuchte eingebaut sind.Coffee machines of the usual design essentially consist of the coffee pot, the filter unit and the housing, in which the flow heater, consisting of the electric heating tube with check valve, hose connections, control unit with thermal fuse, electrical connection cables and the switch with control lamp, are installed from below.
Dieser bekannte Aufbau hat den Nachteil, daß die Montage des kompletten Durchlauferhitzers im Gehäuse der Kaffeemaschine stattfindet. Sowohl die Hand-, als auch die Automatik-Montage sind sehr kostenintensiv, da das große Volumen desThis known design has the disadvantage that the assembly of the entire flow heater takes place in the housing of the coffee machine. Both manual and automatic assembly are very costly, since the large volume of the
-2--2-
Kaffeemaschinengehäuses sich sehr schlecht handhaben läßt und die Gefahr durch Beschädigungen groß ist. Tritt nach längerem Gebrauch der Maschine ein Defekt im Durchlauferhitzer ein, muß die Maschine zur Reparatur in die Kundendienstwerkstatt des Herstellers eingeschickt werden, das meist mit großen Wartezeiten und Kosten verbunden ist. Neuentwicklungen von Kaffeemaschinen erfordern einen hohen Konstruktionsaufwand zur Integration der Durchlauferhitzer - Einzelteile.The coffee machine housing is very difficult to handle and there is a high risk of damage. If a defect occurs in the flow heater after the machine has been in use for a long time, the machine must be sent to the manufacturer's customer service workshop for repair, which usually involves long waiting times and costs. New developments in coffee machines require a high level of design effort to integrate the flow heater's individual parts.
Der im Schutzanspruch 1 angegebenen Erfindung liegt das Problem zugrunde, einen kompakten Durchlauferhitzer zu schaffen, der außerhalb der Kaffeemaschine komplett montiert wird, alle Funktionsteile enthält und als eigenständiges, geprüftes Elektrogerät in das Kaffeemaschinengehäuse eingeschoben und befestigt wird.The invention specified in claim 1 is based on the problem of creating a compact instantaneous water heater that is completely mounted outside the coffee machine, contains all functional parts and is inserted and attached to the coffee machine housing as an independent, tested electrical device.
Dieses Problem wird mit den im Schutzanspruch 1 aufgeführten Merkmalen gelöst.This problem is solved with the features listed in claim 1.
Mit der Erfindung wird erreicht, daß der Kompakt-Durchlauferhitzer als eigenständiges geprüftes Elektrogerät außerhalb der Kaffeemaschine komplett und kostengünstig montiert werden kann. Der Einbau in die Kaffeemaschine erfolgt erst nach Fertigstellung des Gehäuses. Maschinen unterschiedlicher Bauform und Bauart beinhalten den gleichen Durchlauferhitzer, der auch in Heißwasserportionierern für Instantgetränke Verwendung findet.The invention means that the compact instantaneous water heater can be completely and inexpensively installed outside the coffee machine as an independent, tested electrical device. It is only installed in the coffee machine after the housing has been completed. Machines of different shapes and designs contain the same instantaneous water heater that is also used in hot water dispensers for instant drinks.

Im Servicefalle kann der Durchlauferhitzer von Laien selbst ausgetauscht werden. Er kann im Fachhandel als Austauschgerät erhältlich sein. Durch das geschlossene Gehäuse erhalten die mit dem Durchlauferhitzer ausgerüsteten Geräte eine erhöhte elektrische Sicherheit.If servicing is required, the instantaneous water heater can be replaced by laypersons themselves. It can be purchased as a replacement device from specialist retailers. The closed housing gives devices equipped with the instantaneous water heater increased electrical safety.
Eine vorteilhafte Ausgestaltung der Erfindung ist im Schutzanspruch 2 angegeben.An advantageous embodiment of the invention is specified in claim 2.
Die Weiterbildung nach Schutzanspruch 2 für die Anwendung bei Kaffeemaschinen ermöglicht das Anpassen des Schaltereinschubes an die Oberfläche des Gehäuses der Kaffeemaschine.The further development according to protection claim 2 for use in coffee machines enables the switch insert to be adapted to the surface of the housing of the coffee machine.
Ein Ausführungsbeispiel der Erfindung wird anhand der Figur 1 erläutert.An embodiment of the invention is explained with reference to Figure 1.

Das Durchlauferhitzergehäuse 10 ist ein in sich geschlossenes Gehäuse, das von unten mit einer Bodenplatte versehen ist, auf der sich die elektrische Anschlußleitung 12 mit der Zugentlastung befindet. Der Schaltereinschub 11 beinhaltet den Schalter und die Kontrolleuchte und ist entsprechend Farbe, Form und Material dem zugehörigen Kaffeemaschinengehäuse angepaßt.The instantaneous water heater housing 10 is a self-contained housing that is provided with a base plate on the bottom, on which the electrical connection cable 12 with the strain relief is located. The switch insert 11 contains the switch and the indicator light and is adapted to the corresponding coffee machine housing in terms of color, shape and material.

An der Oberseite, in Einschubrichtung, parallel zueinander sind der Wasserzulaufstutzen 7 und der Wasseraustrittsstutzen 8 angebracht. Auf diesen Stutzen befindet sich jeweils eine Schlauchkupplung 9, die eine wasserdichte Verbindung zum Wassertankstutzen 5 und Steigrohrstutzen 3 nach dem Einschieben des Durchlauferhitzers herstellt. Die Außenführungen 13 am Durchlauferhitzergehäuse 10 , in Verbindung mit den Innenführungen 6 im Kaffeemaschinengehäuse 1, gewährleisten ein genaues Erreichen der Fügeposition, in der die Gehäuse miteinander verbunden werden.The water inlet nozzle 7 and the water outlet nozzle 8 are attached parallel to each other on the top side in the direction of insertion. On each of these nozzles there is a hose coupling 9, which creates a watertight connection to the water tank nozzle 5 and riser pipe nozzle 3 after the instantaneous water heater has been inserted. The external guides 13 on the instantaneous water heater housing 10, in conjunction with the internal guides 6 in the coffee machine housing 1, ensure that the joining position in which the housings are connected to each other is reached precisely.
