Abstract

In a series of electric instant heaters, consisting of a pressure pouring part, a tubular heater recessed in a groove of said pressure pouring part, and a throughflow duct moulded into the pouring part for the medium to be heated, said throughflow duct is formed by a chamber with an inlet and an outlet duct. Said chamber is provided with a lid which is screwed onto the pressure pouring part using a seal. This arrangement causes quite considerable, additional production costs and the object of the present invention is to reduce these additional costs to a great extent. This object is achieved in that the throughflow duct (4) is formed by two bores (7 and 8) in the pressure pouring part (1), said bores being arranged at an acute angle (A) to one another and merging into one another at the apex of the angle. <IMAGE>

Elektrischer DurchlauferhitzerElectric water heater

Die Erfindung betrifft einen elektrischen Durchlauferhitzer zur Erwärmung flüssiger Medien, insbesondere zur Verwendung in Kaffeemaschinen oder ähnlichen Geräten gemäß dem Oberbegriff des Patentanspruchs 1.The invention relates to an electric water heater for heating liquid media, in particular for use in coffee machines or similar devices according to the Preamble of claim 1.

Bekannte Durchlauferhitzer dieser Art bestehen aus einem Druckgußteil aus. Aluminium od. dergl. mit eingepreßtem Rohrheizkörper und einem, im Gußteil eingeformten, aus einer Kammer mit Zu-und Ablauf gebildeten Durchlaufkanal.Known water heaters of this type consist of a die-cast part. Aluminum or the like with pressed-in Tubular heating element and a flow channel formed in the cast part and formed from a chamber with an inlet and outlet.

Derartige Durchlauferhitzer genügen vollauf den gegebenen Anforderungen hinsichtlich der Leistungsfähigkeit und der Betriebssicherheit, doch besteht nach wie vor noch die Aufgabe, die Fertigungskosten zu senken, nachdem solche Durchlauferhitzer immer mehr als. Massenartikel angesprochen wer— den müssen.Such water heaters are fully sufficient for the given Requirements in terms of performance and Operational reliability, but there is still the task of reducing manufacturing costs after such water heaters always more than. Mass articles need to be addressed.

Ein wesentlicher Teil dieser Fertigungskosten entstehen bei der Herstellung der genannten Kammer, die mittels eines Deckels, verschlossen werden muß, was außer dem Deckel noch'wenigstens eine Schraube und eine Dichtung erfordert.A significant part of these manufacturing costs arise in the manufacture of the chamber mentioned, which is by means of a Lid, must be closed, which in addition to the lid still requires at least one screw and a seal.

Properties of the pass-through device It s to detrimentally affect so as to lower the manufacturing costs.

Diese Aufgabe wird durch die im Patentanspruch 1 gekennzeichneten Merkmale gelöst.This object is achieved by the features characterized in claim 1.

Bieser neuartige Durchlauferhitzer hat alle Vorteile einer stabilen Druckgußausführung, ist mit wenigen Arbeitsgängen, ohne wesentliche Nacharbeit und somit sehr preisgünstig herzustellen.'This novel instantaneous water heater has all the advantages of a stable die-cast design, with just a few work steps, without significant rework and therefore very inexpensive to manufacture.

Der Durchlauferhitzer besteht aus einem Druckgußteil 1, einem U-förmig gebogenen, mit zwei Anschlüssen 5 und 6 versehenen Rohrheizkörper 2, der in einer entsprechend geformten Nut 3 des Gußteils 1 eingelegt und mit letzterem verpreßt ist und aus einem Durchlaufkanal 4 zur Führung des zu erwärmenden Mediums·The water heater consists of a die-cast part 1, a U-shaped bent, with two connections 5 and 6 provided Tubular heater 2, which is inserted in a correspondingly shaped groove 3 of the casting 1 and pressed with the latter is and from a flow channel 4 for guiding the to heating medium

Der Durchflußkanal 4 wird gebildet von zwei in einem gewissen Winkel A zueinander verlaufenden Bohrungen 7 und 8, die im Scheitelpunkt des Winkels A ineinander übergehen. Diese Bohrungen 7 und 8 werden beim Gießvorgang mittels zweier, in entsprechendem Winkel im Gießwerkzeug angeordneten Seitenschiebern erzeugt, wobei die beiden Schieber mit einem ge-The flow channel 4 is formed by two in a certain way Angle A mutually extending holes 7 and 8, the merge into each other at the apex of angle A. These holes 7 and 8 are during the casting process by means of two, in generated sideshifts arranged in the casting tool at a corresponding angle, the two slides with a

Die Ausgänge der beiden Bohrungen 7 und 8 münden in zwei Anschlußstutzen 9 und 10, die Verjüngungen aufweisen, so daß ein Schlauch aus Silikon od.dergl· aufgeschoben werden kann·The outputs of the two holes 7 and 8 open into two Connection pieces 9 and 10, which are tapered, so that a hose made of silicone or the like can be pushed on can·

Die beschriebene Druckgußausführung hat den weiteren Vorteil, daß in der Verwendung für Kaffeemaschinen die Warmhalteplatte gleich mitangeformt werden kann· Diese Platte 11 kann außerdem mit einer Beschichtung Λ2. aus Teflon ode dergl· versehen werden, so daß der Durchlauferhitzer schon einen weitgehend kompletten Teil einer Kaffeemaschine oder eines ähnlichen Geräts bilden kann·The die-cast design described has the further advantage that when it is used for coffee machines, the hotplate can be molded on at the same time. This plate 11 can also be coated with a Λ2. Teflon od e · the like are provided, so that the water heater can already form a substantially complete part of a coffee machine or a similar device ·
