Claims (2)

<Desc/Clms Page number 1>  <Desc / Clms Page number 1>   Die Erfindung bezieht sich auf einen elektrischen Durchlauferhitzer gemäss dem einleitenden Teil des unabhängigen Patentanspruches.  The invention relates to an electric instantaneous water heater according to the introductory part of the independent claim. Bei bekannten derartigen Durchlauferhitzern ist der Kanal zur Führung des Wassers durch ein Rohr gebildet, das an der Rückwand gehalten und das mäanderförmig verlegt ist. Dabei ist die Heizwendel um die Rohre gewickelt.  In known instantaneous water heaters of this type, the channel for guiding the water is formed by a tube which is held on the rear wall and which is laid in a meandering shape. The heating coil is wrapped around the pipes. Ein solcher Aufbau erfordert einen sehr erheblichen Herstellungsaufwand.  Such a structure requires a very considerable manufacturing effort. Im übrigen ist aus der DE 196 32 459 A1 ein Heizblock für einen Wasserdurchlauferhitzer be- kanntgeworden, der aus zwei Gehäusehälften besteht, die, nachdem Heizdrähte eingelegt worden sind, aneinandergesetzt und vorzugsweise in einem Vibrationsschweissverfahren miteinander verschweisst werden. Damit ist der Heizblock fertiggestellt und kann als Heizblockbaugruppe in einen Durchlauferhitzer-Warmwasserbereiter eingebaut werden, der also mithin dann seinerseits das Gehäuse des elektrischen Durchlauferhitzers bildet. Auch ein solcher Aufbau erfordert einen sehr erheblichen Herstellungsaufwand.  For the rest, from DE 196 32 459 A1 a heating block for a water heater has become known which consists of two housing halves which, after heating wires have been inserted, are placed next to one another and are preferably welded to one another in a vibration welding process. This completes the heating block and can be installed as a heating block assembly in a water heater water heater, which in turn forms the housing of the electrical water heater. Such a structure also requires a very considerable manufacturing effort. Ziel der Erfindung ist es, den eingangs geschilderten Nachteil zu vermeiden und einen elektri- schen Durchlauferhitzer vorzuschlagen, der sich durch einen einfachen Aufbau auszeichnet.  The aim of the invention is to avoid the disadvantage described at the outset and to propose an electric instantaneous water heater which is distinguished by a simple construction. Erfindungsgemäss wird dies bei einem elektrischen Durchlauferhitzer der eingangs erwähnten Art durch die kennzeichnenden Merkmale des unabhängigen Patentanspruches erreicht.  According to the invention, this is achieved in an electric instantaneous water heater of the type mentioned at the outset by the characterizing features of the independent patent claim. Durch die vorgeschlagenen Massnahmen erübngt sich die Herstellung des mäanderförmig ver- formten Rohres. Ausserdem ist auch die Einbettung einer Heizwendel in die Rückwand erheblich einfacher als die Aufbringung der Wendel auf ein Rohr. Dabei kann der Kanal zur Führung des Wassers einfach durch Einarbeiten entsprechender Vertiefungen in den aneinander anliegenden Flächen der Rückwand und der Abdeckung bestimmt werden.  As a result of the proposed measures, the manufacture of the meandering tube is no longer necessary. In addition, embedding a heating coil in the rear wall is considerably easier than applying the coil to a pipe. The channel for guiding the water can be determined simply by incorporating corresponding depressions in the abutting surfaces of the rear wall and the cover. Der wesentliche Effekt durch die Massnahmen der Erfindung liegt allerdings darin, dass die Rückwand des Kanalkörpers zugleich die Rückwand des elektrischen Durchlauferhitzers bildet, so dass also eine Gehäuserückwand entfallen kann.  The essential effect of the measures of the invention, however, is that the rear wall of the channel body also forms the rear wall of the electric instantaneous water heater, so that a rear wall of the housing can therefore be dispensed with. Die Erfindung wird nun anhand der Zeichnungen näher erläutert. Dabei zeigen: Fig. 1 eine Ansicht des erfindungsgemässen Durchlauferhitzers und Fig. 2 einen Schnitt nach der Linie A-A in der Fig. 1.  The invention will now be explained in more detail with reference to the drawings. Show: Fig. 1 is a view of the instantaneous water heater according to the invention and FIG. 2 shows a section along the line A-A in FIG. 1. Der Durchlauferhitzer 1 weist einen Kaltwasseranschluss 2 und einen Warmwasseranschluss 3 auf. Diese sind mit einem durch in die aneinander anliegenden Flächen 14,15 einer Rückwand 4 und einer Abdeckung 5 eingearbeiteten Vertiefungen 6,7 gebildeten Kanal 8 verbunden, der zur Führung des zu erwärmenden Wassers dient.  The instantaneous water heater 1 has a cold water connection 2 and a hot water connection 3. These are connected to a channel 8, which is formed by recesses 6, 7 machined into the abutting surfaces 14, 15 of a rear wall 4 and a cover 5 and which serves to guide the water to be heated. In der Abdeckung 5 ist weiters eine Heizwendel 9 eingebettet, deren Anschlüsse 10 die Abde- ckung durchsetzen.  A heating coil 9 is also embedded in the cover 5, the connections 10 of which pass through the cover. An der Abdeckung 5 sind weiters Befestigungselemente 11, 12 angeformt, die zur Befestigung einer nicht dargestellten Verkleidung und einer Sicherheitseinrichtung dienen.  Fastening elements 11, 12 are also formed on the cover 5 and are used for fastening a cladding (not shown) and a safety device. PATENTANSPRÜCHE : 1. Elektrischer Durchlauferhitzer mit einer Geräterückwand und einem zweiteiligen Kanalkör- per, der einen Kanal (8) zur Führung des Wassers samt Anschlüssen (2,3) für Kalt- und Warmwasser und eine Heizwendel (9) aufweist, wobei in der Rückwand (4) des Kanalkör- pers und einer mit dieser verbundenen Abdeckung (5) an den einander anliegenden Flä- chen einander entsprechende Vertiefungen (6. 7) eingearbeitet sind, die gemeinsam den zur Führung des zu erwärmenden Wassers dienenden Kanal bilden, der mit den Anschlüs- sen (2,3) verbunden ist, wobei die Heizwendel (9) in einem dieser beiden Teile (4,5) ein- gebettet ist, dadurch gekennzeichnet, dass die Rückwand (4) des Kanalkörpers (4') zugleich die Geräterückwand bildet.  PATENT CLAIMS: 1. Electrical instantaneous water heater with a rear panel and a two-part channel body, which has a channel (8) for guiding the water, including connections (2, 3) for cold and Warm water and a heating coil (9), wherein in the rear wall (4) of the channel body and a cover (5) connected to it on the abutting surfaces, corresponding depressions (6. 7) are worked in together to serve to guide the water to be heated, which is connected to the connections (2, 3), the heating coil (9) being embedded in one of these two parts (4, 5), characterized in that the Rear wall (4) of the channel body (4 ') also forms the rear wall of the device. 2. Durchlauferhitzer nach Anspruch 1, dadurch gekennzeichnet, dass an der Abdeckung (5) Befestigungselemente (11,12) zur Halterung einer Verkleidung und von Sicherheitsein- richtungen angeordnet sind. **WARNUNG** Ende CLMS Feld Kannt Anfang DESC uberlappen**.  2. instantaneous water heater according to claim 1, characterized in that on the cover (5) Fastening elements (11, 12) for holding a cladding and safety devices are arranged. ** WARNING ** End of CLMS field knows overlap beginning of DESC **.
